sections at the Addison Airport. Task 9.1 -Pavement Strength Analysis Description: This task consists ofcoring and evaluating several pavement sections at the Addison Airport. The pavement
corings will be tested and evaluated in accordance with applicable ASTM and FAA standards. Up to 32 corings will be obtained. Seven (7) on the Runway, eight (8) on the parallel taxiway,
and seventeen (17) at other apron and taxilane locations. The 32 cores will be tested for compressive strength and eight (8) companion cores will be tested for tensile strength. B-22
"FINAL" (November 7, 2001) 
Results of both the compressive and tensile strength tests will be used tc evaluate the flexural strength ofthe pavement at each location. The flexural strength for single wheel loads
(SWL, dual wheel loads (DWL), and dual tandem wheel loads (DTWL) will be calculated for each location. A letter style report will be prepared and included in an appendix to the master
plan report which will address 1.) Thickness and brief visual description ofeach core; 2.) Compressive and tensile strength test results; and 3.) Pavement strength for SWL, DWL, and
DTWL at each location. Responsibilities: Consultant: Conduct pavement corings, evaluate corings, and prepare a pavement strength analysis report. Sponsor: Review. Coordinate with Consultant
as necessary. Provide airport access to the pavement testing firm and coordinate runway closures for testing. Product: Pavement strength analysis report for inclusion as an appendix
