June 6,2003 Mr. James C. Pierce, Jr., P.E. Assistant Public Works Director Town ofAddison 16801 Westgrove Drive Addison, Texas 75001 SUbject: Proposal for Runway Evaluation -Addison
Airport MACTEC Proposal No. PROP03DALL-0295 Dear Mr. Pierce: MACTEC is pleased to provide this proposal for pavement evaluation services at Addison Airport, Texas. OBJECTIVE AND SCOPE
OF WORK We understand that the Town of Addison is currently working with the FAA and Coffman Associates Airport Consultants to develop an updated master plan for the airport. In support
of this planning effort the Town of Addison wishes to undertake an evaluation of the existing RW 15/33. The runway is constructed of asphalt concrete and is approximately 7200 ft long
and 100 ft wide. Thickness ofthe asphalt concrete layer is reported to vary from 7 to 15 inches. The objective of this work is to provide the Town of Addison with an evaluation of the
existing condition of the runway pavement and preliminary design alternatives for rehabilitation or reconstruction, to support the master planning activity. Our effort is proposed in
accordance with FAA Advisory Circular AC 150/5320-60 for pavement evaluations. Detailed design (plans, specifications and estimates) of the selected rehabilitation option is not within
the scope of this proposal. Additional materials sampling and testing beyond that proposed here will be required at a later date to comply with FAA requirements for detailed design.

Town ofAddison Airport June 6,2003 MACTEC Reforence PROP03DALL,0295 To conduct this work, MACTEC will perform the following tasks: Task 1. Pavement Inspeetion and Testing We understand
inspection and testing will be coordinated with airport operations staff, and likely scheduled to occur at night. Any required FAA permits/documents should be obtained for our employees
by the Town of Addison, MACTEC will perform visual condition surveys of the existing asphalt pavement in accordance with procedures adopted by the Federal Aviation Administration and
outlined in ASTM DS340 "Standard Test Method for Airport Pavement Condition Index Surveys," The surveys will be completed on a sample basis at a nominal coverage of SO% ofthe surface
area over a three-day (equivalent) period, We recommend this level of inspection based upon the age and likely condition of the runway. Although PCl inspections can be conducted using
light cart operations, as a minimum we will require some twilight hour access to the runway. We will conduct two days (equivalent) of nondestructive testing using a MACTEC owned and
operated Dynatest Model 8002 Falling Weight Deflectometer. Testing will be conducted along six adjacent lines across the width of the runway separated by a minimum of 10ft, Spacing between
test points will range from 100 to 300 ft in accordance with Advisory Circular AC ISO/5370-11B "Use ofNondestructive Testing in the Evaluation of Airport Pavements." Based upon boring
results previously conducted by Reed Engineering and provided to MACTEC to support this proposal, we note considerable variation in the thickness ofthe existing pavement. We propose
to perform one day (equivalent) of additional pavement coring to determine pavement structure thickness. Locations will be selected based upon pavement variations determined from FWD
test results, Task 2. Data Analysis and Pavement Design Based upon information obtained in Task 1 and other information that the Town of Addison may provide to us, we will evaluate the
existing pavement structural and functional condition, and develop alternative preliminary designs, We will require summary aircraft traffic information from the Town of Addison or Coffman
Associates, and we will rely on this information in our analysis. Any drawings or documentation that the Town of Addison is able to provide pertaining to original construction and subsequent
maintenance and rehabilitation will aid in the evaluation process. Design alternatives will include rehabilitation options based upon 8 and IS-year design lives (or substitute analysis
periods specified by the Town of Addison), and reconstruction, 􀁉􀀣􀁐􀁾􀀠leW 7/), 􀁦􀁾􀀠 16"0 􀁊􀁾􀁰􀁾􀀠 3ttO

Works Director Proposal for Pavement Evaluation and Overlay Design of Runway at Addison Airport, Addison, Texas Fugro South, Inc. is pleased to submit this proposal for the pavement
evaluation and design of a runway pavement section at Addison Airport in Addison, Texas. To accomplish this objective the following tasks are anticipated: Project Level Deflection Testing.
Geotechnical Sampling and Testing Design, Analysis and Reporting. The following sections of this proposal describe the scope of our services, a cost estimate for the engineering services
to be provided, an estimated schedule, and proposed terms and conditions. Project Description The Town of Addison is planning to evaluate the existing pavement section of the existing
7200foot runway at Addison Airport located near 8elt Line Road and Addison Road. The firm of Coffman Associates is performing a master plan and 7 soil borings have been taken through
the existing HMAC pavement section. Project Level Deflection Testing Nondestructive deflection testing will be performed at a spacing of approximately 100 feet along the center (keel
section) and edge (wing section) of the 7,200 foot of runway (approximately 154 test points). The purpose of the deflection test program is to determine the structural response characteristics
of the pavement structure to whee! loads as well as variability of the structural 
properties along the pavement sections. The deflection testing program will be performed in accordance with ASTM Test Standard 04694 (Standard Test Method for Deflections With a Falling
Weight-Type Impulse Load Device) and 04695 (Standard Guide for General Pavement Deflection Measurements). The type of testing to be conducted will be a Level 3 program, for a detailed
evaluation of pavement condition. Pavement Materials Sampling The material sampling operations may require additional cores and borings to a minimum of 5 feet in depth along the runway
at specified locations by the pavement engineer. The additional amount of borings (if any) will be determined after the deflection testing and review of the 7 bOrings provided by the
City of Addison. If additional borings are required, the sampling personnel will identify or note any seepage of water in the underlying pavement and soil layers during the materials
sampling program. Thicknesses of each pavement layer will be measured to an accuracy of Y.i in and provided to the pavement engineer. These core holes will be patched using equivalent
quality materials. This work will be coordinated by Fugro-South. Fugro-South can provide a proposal for these services if requested. Design, Analysis and Backcalculation Using the non-destructive
deflection testing data, and borings (which will be provided and will contain pavement layer descriptions and thickness), the roadway will be analyzed to identify those areas that respond
differently to loads. Layer moduli will be calculated using the Army Corps of Engineers backcalculation procedures (WESDEF). Additional information from the City of Addison will be required
by Fugro to determine the required thickness of the overlay or other rehabilitation alternatives. This includes the type of aircraft and the anticipated arrivals and departures over
the 20-year design period. If changes in aircraft type are expected in the design period, the City of Addison should provide this information as it will have significant impact on the
amount of material required to increase the structural capacity of the pavement structure. Report of Results An engineering report will be prepared that will document all field work
and engineering analyses. All data, test results and pertinent information will be provided in the engineering report. This will include, as a minimum, the following; 1. A general description
of the pavement condition based on the deflection testing including deflection profile plots. 2. The results of the backcalculated moduli. 
3. The recommended rehabilitation including overlay thickness with construction recommendations. Cost Estimate Based on the scope of work outlined above and Fee Schedule P-2002, the

Design of Runway at Addison Airport, Addison, Texas Fugro South, Inc. is pleased to submit this proposal for the pavement evaluation and design of a runway pavement section at Addison
Airport in Addison, Texas. To accomplish this objective the following tasks are anticipated: Project Level Deflection Testing. Geotechnical Sampling and Testing Design, Analysis and
Reporting. The followi ng sections of this proposal describe the scope of our services, a cost estimate for the engineering services to be provided, an estimated schedule, and proposed
terms and conditions. Project Description The Town of Addison is planning to evaluate the existing pavement section of the existing 7200foot runway at Addison Airport located near Belt
Line Road and Addison Road. The firm of Coffman Associates is performing a master plan and 7 soil borings have been taken through the existing HMAC pavement section. Project Level Deflection
Testing Nondestructive deflection testing will be performed at a spacing of approximately 100 feet along the center (keel section) and edge (wing section) of the 7,200 foot of runway
(approximately 154 test points). The purpose of the deflection test program is to determine the structural response characteristics of the pavement structure to wheel loads as well as
variability of the structural A member of the Fugro group 01 companies with offices throughout the WOrld.-@---------_.....................

Test Method for Deflections With a Falling Weight-Type Impulse Load Device) and D4695 (Standard Guide for General Pavement Deflection Measurements). The type of testing to be conducted
will be a Level 3 program, for a detailed evaluation of pavement condition. Pavement Materials Sampling The material sampling operations may require additional cores and borings to a
minimum of 5 feet in depth along the runway at specified locations by the pavement engineer. The additional amount of bOrings (if any) will be determined after the deflection testing
and review of the 7 borings provided by the City of Addison. If additional borings are required, the sampling personnel will identify or note any seepage of water in the underlying pavement
and soil layers during the materials sampling program. Thicknesses of each pavement layer will be measured to an accuracy of Y.i in and provided to the pavement engineer. These core
holes will be patched using equivalent quality materials. This work will be coordinated by Fugro-South. Fugro-South can provide a proposal for these services if requested. Design, Analysis
and Backcalculation Using the non-destructive deflection testing data, and borings (which will be provided and will contain pavement layer desCriptions and thickness), the roadway will
be analyzed to identify those areas that respond differently to loads. Layer moduli will be calculated using the Army Corps of Engineers backcalculation procedures (WESDEF). Additional
information from the City of Addison will be required by Fugro to determine the required thickness of the overlay or other rehabilitation altematives. This includes the type of aircraft
and the anticipated arrivals and departures over the 20-year design period. If changes in aircraft type are expected in the design period, the City of Addison should provide this information
as it will have significant impact on the amount of material required to increase the structural capacity of the pavement structure. Report of Results An engineering report will be prepared
that will document all field work and engineering analyses. All data, test results and pertinent information will be provided in the engineering report. This will include, as a minimum,
the following: 1. A general description of the pavement condition based on the deflection testing including deflection profile plots. 2. The results of the backcalculated moduli. -@
3. The recommended rehabilitation including overlay thickness with construction recommendations. Cost Estimate Based on the scope of work outlined above and Fee Schedule P-2002, the

andAnalysisfor Addison Airport Runway Dear Mr, Pierce: I appreciate your allowing us to provide this proposal for nondestructive testing and analysis on the above mentioned airport,
We look forward to working with you on this project, Dynatest proposes to utilize its Heavy Weight Deflectomber to collect pavement surface deflection data on this runway, The deflections
will be used along with traffic data and pavement thickness information obtained from pavement corings and Ground Penetration Radar (GPR) testing to detennine the overall structural
condition of the runway, Specifically, Dynatest will utilize this data to calculate the approximate remaining life at each point tested, Ifthe remaining life is found to be deficient,
the asphalt overlay thickness required to achieve the desired service life (20 years) will be calculated as well, We propose to test at 50 ft. intervals along three lines, one along
the runway centerline and the other two on either side of the centerline. Each series of test points will be staggered by roughly 16 ft. (in the longitudinal direction) with respect
to the previous series to improve coverage, The total number of test points is estimated at 432 which will require 16 hours to complete assuming we have continuous access to the runway
at 8 hour shifts. Thus we can anticipate 2 workdays to complete the testing portion of the job. If the testing is extended more than 16 hours due to accessibility limitations, additional
testing time will be charged at $240 per hour. We can work either during daylight hours or at night, whichever is most productive or convenient for the airport, DYNATEST CONSULTING.

-Addison Airport MACTEC Proposal No. PROP03DALL-0295 Dear Mr. Pierce: MACTEC is pleased to provide this proposal for pavement evaluation services at Addison Airport, Texas. OBJECTIVE
AND SCOPE OF WORK We understand that the Town of Addison is currently working with the FAA and Coffinan Associates Airport Consultants to develop an updated master plan for the airport.
In support of this planning effort the Town of Addison wishes to undertake an evaluation of the existing RW 15133. The runway is constructed of asphalt concrete and is approximately
7200 ft long and 100 ft wide. Thickness ofthe asphalt concrete layer is reported to vary from 7 to 15 inches. The objective of this work is to provide the Town of Addison with an evaluation
of the existing condition of the runway pavement and preliminary design alternatives for rehabilitation or reconstruction, to support the master planning activity. Our effort is proposed
in accordance with FAA Advisory Circular AC 15015320-6D for pavement evaluations. Detailed design (plans, specifications and estimates) of the selected rehabilitation option is not within
the scope of this proposal. Additional materials sampling and testing beyond that proposed here will be required at a later date to comply with FAA requirements for detailed design.

Town ofAddison Airport June 6. 2003 MACTEC Reference PROP03DALL.0295 To conduct this work, MACTEC will perfonn the following tasks: Task 1. Pavement Inspection and Testing We understand
inspection and testing will be coordinated with airport operations staff, and likely scheduled to occur at night. Any required FAA pennitsldocuments should be obtained for our employees
by the Town ofAddison. MACTEC will perfonn visual condition surveys of the existing asphalt pavement in accordance with procedures adopted by the Federal Aviation Administration and
outlined in ASTM D5340 "Standard Test Method for Airport Pavement Condition Index Surveys." The surveys will be completed on a sample basis at a nominal coverage of SO% ofthe surface
area over a three-day (equivalent) period. We recommend this level of inspection based upon the age and likely condition of the runway. Although PCl inspections can be conducted using
light cart operations, as a minimum we will require some twilight hour access to the runway. We will conduct two days (equivalent) of nondestructive testing using a MACTEC owned and
operated Dynatest Model 8002 Falling Weight Deflectometer. Testing will be conducted along six adjacent lines across the width of the runway separated by a minimum of lOft. Spacing between
test points will range from 100 to 300 ft in accordance with Advisory Circular AC IS0/5370-IIB "Use ofNondestructive Testing in the Evaluation of Airport Pavements." Based upon boring
results previously conducted by Reed Engineering and provided to MACTEC to support this proposal, we note considerable variation in the thickness of the existing pavement. We propose
to perfonn one day (equivalent) of additional pavement coring to detennine pavement structure thickness. Locations will be selected based upon pavement variations detennined from FWD
test results. Task 2. Data Analysis and Pavement Design Based upon infonnation obtained in Task I and other infonnation that the Town of Addison may provide to us, we will evaluate the
existing pavement structural and functional condition, and develop alternative preliminary designs. We will require summary aircraft traffic infonnation from the Town of Addison or Coffinan
Associates, and we will rely on this infonnation in our analysis. Any drawings or documentation that the Town of Addison is able to provide pertaining to original construction and subsequent
maintenance and rehabilitation will aid in the evaluation process. Design alternatives will include rehabilitation options based upon 8 and IS-year design lives (or substitute analysis

Jim; My plans are to talk to the folks in the pavement testing section of TxOOT to see jfwe can develop a better, more timely method of accomplishing non-destructive field testing (
NOT) with the TxOOT falling weight defiectometer, ground penetrating radar, and profilometer. These are the types of data that should be collected at Addison, and in theory, could be
collected by TxDOT. In addition to the NOT, additional coring and lab testing should be performed, and TxDOT typically does not do this work on airports. Therefore, even if we are able
to get TxOOT to perform the NOT da1a collection, they will still need a consultant to do coring, lab work, and data analysis. There are two consultants that I know of that have the equipment
and experience to do that type of work. They are: HVJ Engineering Austin Unda Barlow 512-447-9081 Fugro Oallas 972-484-8301 That's alii have for now. Ed >>> Bruce Ehly 06/02103 10:44AM

tasks facing the Nation's transportation community is 􀁲􀁮􀁡􀁩􀁮􀁾􀀠taining existing assets in a sound condition. This readiness is essential to support the level ofoperations and provide
the degree of serviceability the transportation infrastructure was designed to handle. In the ongoing quest to create better data collection and assessment tools. the Federal Highway
Administration (FHWA), through the Small Business Administration, contracted ARA to develop the Rolling Wheel Dellectometer (RWD). This device is suitable for 􀁮􀁥􀁴􀁷􀁯􀁲􀁫􀁾􀁬􀁥􀁶􀁥􀁬􀀠analysis
(Le., pavement management-type applications) ofthe pavement's structural capacity. Currently, the data collected for use in a pavement management system (PMS) include assessment of the
surface distress condition of pavements and generally ignore the structural support and integrity. However, a pavement that exhibits little or no distress may not be structurally adequate
to support anticipated traffic. Conversely, a pavement with a highly distressed surface may be structurally sound, requiring only surface maintenance and 􀁲􀁥􀁮􀁯􀁾􀀠vatton. Therefore,
it is advantageous for an agency to collect information on both the functional and structural condition ofits pavement network to provide a complete analysis of pavement maintenance/rehabilitation
and funding needs. Progressing from a Static to a Moving Load Unlike the Falling Weight Dellectomoter (FWD), which takes data while stopped at designated test points, the RWD collects
data while traveling at normal highway speeds. This allows a significant increase in the Ali I!.Xilmple graph showing the strae/lIm! /J,dex/mm lite Rolling Ut'eiglst Deflcclometcr. -----""...T..."w,•

and lane closures. A number offactors can influence the measurement of pavement deflection under a moving wheel load, including: • Wheel load and geometry. • Tire pressure. • Vehicle
speed. • Temperature of the pavement surface. The RWD takes into account all of these factors, except for one. Currently, the RWD does not monitor wheel load variations, but future improvements
to the device will add this capability. Also, because the deflection basin under rolling wheels is not symmetrical, the research team had to detennine the best location to collect deflection
data. Historically, most data have been collected using the basin behind (trailing) the wheel. However, the RWD uses the basin ahead of (leading) the wheel because it can more easily
be compared to the undeflected pavement ahead of the load wheel. Additionally, the leading part ofthe basin may be less influenced by hysteresis effects. The ARA RWD uses a scanning
laser system (SLS) developed by Phoenix Scientific, Inc. The SLS scans a 14-ft length of pavement in 1 millisecond from a single reference point. This is a significant difference from
other rolling wheel deflection systems, both operational and prototype, in which a single sensor only measures the point on the pavement dircctly beneath the sensor. Advantages of the
scanning laser include the following: • More powerful laser. • Larger laser footprint. • High sampling rate. • Longer standoff distance. • No limitations on measurement distance. • No
concern for reference beam alignment. • Measures full deflection basin. • Collects both deflected and undeflected surface data in one sweep. Data Processing The RWD data processing unit
includes software that was developed to provide two methods of statistical treatment: low resolution and high resolution. The lowresolution method avcrages the deflection basin from
a specified length ofroadway (say, 500 ft or 0.25 miles) and averages the results into a single representative deflection basin. The high-resolution method produces deflection basins
at more closely spaced increments. The deflection basin can then be converted to a structural index that rates the pavement structural capability on a numerical scale from 1 to 10. Status
of RWD Development ARA has completed the first generation RWD, and initial testing on roadways near our Vicksburg, Mississippi, office have demonstrated that the RWD can measure deflection
basins under the moving wheel load at speeds up to 55 mph. However, tests at the Ohio Test Road failed to validate the RWD deflection measurements when compared to linear variable differential
transfonners (LVDTs) in the Test Road pavements. Based on these results, further work on the SLS was deemed necessary. A second round of validation tests will be made at the Ohio Test
Road once this work has been completed. The ROiling Weight Deflectometer travels at highway speeds while collecting deflection response data to be used in computation of the Pavement
Structural Index. F Page 2

deflection gage data and the RWD measurements. 2D and 3D Finite Element Analysis The performance of rigid pavements depends on the stresses and deflections imposed by repeated traffic
and environmental loadings. For example. transverse cracking in jointed plain concrete pavement (JPCP) is governed by the maximum tensile stresses at the bottom (ort as recently discovered,
at the top) ofthe concrete slab. In eonlrast, crack deterioration in jointed reinforecd concrete pavements (JRCP) and continuously reinforced concrete pavements (CRCP) can be related
to the shear stresses at the crack surface. Therefore, reliable predictions of pavement responses are essential for a mechanistic-empirical design procedure. The structural model used
for those predictions must satislY the following requirements: • Adequately describe the pavement Structure (constructed layers and subgrade). • Model discontinuities (cracks and joints)
in the pavement structure. • Analyze multi-wheelloadiog with nonuniform tire print distribution, III Analyze environmental loading such as temperature curling and moisture warping. Finite
element methods pennit development of structural models that satisfy all these requirements. A variety of finite element programs are available to pavement engineers today. These programs
may be broadly oategorized as general-purpose finite element programs and 􀁳􀁰􀁥􀁣􀁩􀁡􀁬􀁾􀁰􀁵􀁲􀁰􀁯􀁳􀁥􀀠codes developed for the analYff sis of pavement systems. The general-purpose
programs have much broader applieation and are of interest to many disciplines of science and engineering, and many sophisticated commercial products can conduct three·dimensional nonlinear
dynamic analysis, These programs have been used successfully for pavement analysis in several researeh studies, and a number of finite clement models built using these products are available
today. However, these programs usually demand considerable computational resources, as well as time for developing a structural model for each problem. Most of the programs developed
especially for analysis of concrete pavement systems, including ILU-SLAB (Tabatabaie and Barenberg 1980), can analyze multi-wheel loading of one-or two-layered medium thick plates resting
on a Winkler foundation or an elastic solid. The latest enhancements to ILU-SLAB include ILSL2, developed at tbe University of Illinois, and a revised version oflLSL2 developed by ERES
Consultants (Khazanovich 1994, Khazanovich and Yu 1998). These two programs contain many advanced features that distinguish them from other pavement programs that are based on plate
theory. =􀁾Page3

purposes, let us look at a couple of representative general-purpose and specialized finite element programs, ABAQUS and ILSL2 ABAQUS is a very powerful and reliable generalpurpose) production-oriente
d, finite-3D, dynamic, nonlinear finite element code designed to address structural and heat transfer problems, ABAQUS inCOrPorates implicit and explicit dynamic soJvers to aHow analysis
of a wide range of linear and nonlinear applications, The ABAQUS solvers are well integrated, allowing a single analysis to switch between solvet'll as needed, ABAQUS is the most powerful
general-purPose code available, and most 3D finite element models, including NCHRP 1-30 (Darter ct .1. 1995) were developed using it. TLSL2 (Khazanovich 1994) is the latest publie domain
revision of the finite element program ILLI-SLAB. The features that distinguish It from all other programs are as follows (Khazanovlch 1994, KJummovich and Yu 1998): • A wide selection
of subgrade models, including Winklerf elastic solid. Pasternak, 􀁋􀁥􀁲􀁲􀁾Vlasov, and Zhemochkln-Sinitsyn-Shtaerman. • An ability to analyze the effect of the independent actions of
two pavement layers. • An abmty to analyze the effect of linear and nonlinear temperature distribution throughout the pavement 􀁴􀁨􀁩􀁣􀁫􀁾􀁮􀁥􀁳􀁳􀀮􀀠• An ability to analyze partial-depth
cracks. Comparison of ABAQUS and ILLI-SLAB Hammons (1997) conducted a comprehensive comparison of ABAQUS and ILLI-SLAB, He eonsidered several cases of a single slab resting on a Winkler
foundation and loaded by a single load at its interior or at the edge. The following conclusions were made: l. A very good eorreJation was found between ILLISLAB and ABAQUS for the maximum
bending stresses when an interior loading condition was considered, 2, The maximum deflections predicted by lLLI-SLAB were consistently 1to 2 percent lower than those predicted by ABAQUS
(when an acceptable level of accuracy is achieved in ABAQUS). 3. The greatest discrepancy was found for maximum bending edge stresses. Whereas ILLI-SLAB predicts the ioeation of the
maximum edge stresses right at the slab edge, results ftom comprehensive 3D ABAQUS Stresses in X-Direction Deflections .. GrapiIical outpllt from ISLAB2(J(J(J depictillg slab analpsis.

and is approximately 10 percent less than predicted by ILLI-SLAB. However, this difference is consistent and should not affect performance prediction, since a consistent 􀁤􀁩􀁳􀁣􀁲􀁥􀁰􀁾􀀠aney
can be accounted for in the fatigue model calibration. Hammons also examined the joint model used in ILLl-SLAB, Based on analysis of field test data and on comparison with the ABAQUS
model, he concluded that although the ILL!SLAB model is dramatically less computationally demanding than the ABAQUS model, it provides sufficient accuracy for a gross analysis of pa
vement systems. Although explicit modeling oflhe dowel in the 3D model is perhaps useful for research purposes, it is unnecessarily complicated for practical purposes. New Program Development
The newest finite-element program dedicated to pavement analysis is currently under development. ERES, in cooperation with the Michigan and Minnesota Departments of Transportation, Michigan
Technical University, the UniverSity of 􀁍􀁩􀁣􀁨􀁪􀁧􀁡􀁮􀁾􀀠Michigan State University. and the University of Minnesota> is developing a new finite element code, ISLAB2000. The new program
will retain all the positive features of ILLI-SLAB but will be more computationally efficient,. contain many improved capabilities, and provide a user· friendly interface. Like ILSL2,
Ihe first version of ISLAB2000 will support only plate elemenls, but the system was designed for the future addition of other elements, ISLAB2000 will be a significant improvement over
all existing finite-element programs for pavement analysis-even the first version will enable users to analyze a wide range of problems that are not possible with the existing programs.
For example, ISLAB2000 will be able to analyze mismat<;hed joints, parlially bonded layers, and the effect of widened base, A detailed description of ISLAB2000 is scheduled to appear
in a future issue of Aye on ERES, Conclusion Although general-purpose 3D finite element programs are powerful tools for sophisticated research studies. specialized pavement programs-Uke
ILSL2 and ISLAB2000-are better suited for routine pavement analysis. They are much easier to use and are able to model aH of the important features of the pavement systems, ILSL2 and
ISLAB2000 are also much less computationally demanding than general-purpose programs. .. For more informatioll aboutjillife elemelll analysis, COlllact Dr. Lev Kilazanovich at (217)

Division can now provide new engineering services to its clients. That is, ERES Consultants, Inc. provided some services that ARA did not, and vice versa. The merger has also allowed
us wider coverage in some services in which both companies excelled. One of the areas in which both ERES and ARA have enjoyed tremendous success is in pavement condition surveys. For
the past 3 years, ARA has been conducting pavement condition surveys for the U.S. Air Force. This work is funded by various Air Force Commands through contracts administered by the Air
Force Civil Engineering Support Agency (AFCESA) at Tyndall Air Force Base (AFB), Our 1999 work includes 12 Air Force bases under three commands. The work consists of using the pavement
condition index (PCI) method to survey the airfield pavements at specified Air Force bases. Visual distress data are an excellent source of pavement condition infonnation and are used
in many ways by airfield pavement engineers, planners, and maintenance personnel. Pavement distress data are Severely cracked airJield pavemellt. The PCI Sllrvey reqllires measurement
ofdistress types, sC!Verity 1(!I'el, ami extent. used to evaluate pavement perfonnance and are a basic input to pavement management systems. The key to a useful pavement condition evaluation
lies in the objectivity and reliability of the survey procedures, The PCI procedure, outlined in AFR 93-5 and further refined in ASTM Standard D5340, is used by the aviation industry
to visually assess current airfield pavement condition. Dr. Michael Darter, a Principal Engineer in the ERES Division, was onc of thc co-dcvelopers of this procedure. The current Air
Force project involves entering the measured distress data into a computerized pavement management system (MicroPAVER). The condition infonnation is then analyzed, along with local maintenance
and materials costs and other data, to develop a 5-year work plan for the maintenance of each base's pavements. ARA is also providing a variety of reports and documents, CAD drawings,
and color-coded maps that show the PCI results for the surveyed pavements. Upon submittal of the draft report to each base, Dr. Jim Hall conducts a 2-day training session to base personnel
on the use and applicalions of the pavement management system. For more illformation about tltis project, contact Dr. Jim Hall at (601) 638-5401 (e-mail: jllQlI@ftra.com). Jim is tile
