Architect for approval. 2.5 Strength Requirements The unconfined compressive strengths required for the CTB material will be as follows: 2.5.1 Class A CTB; 400 psi -seven days 3.0 EQUIPMENT 3.1 Description Cement Treated Base may be constructed with any combination of machines or equipment that will produce the results meeting these specifications. CTB-2 03/94 4.0 CONSTRUCTION METHODS 4.1 Preparation Before olber construction OpetliliODS are begun. !be area to be paved shall be gnuIed and shaped as required to receive !be Cement Treated Base in conformance with the grades, lines. thicknesses and typical cross-section shown on !be plans. UDSIlitable subgmde soil or mlllerial shall be removed and replaced with acceptable soil. The subgrade shall be firm and able to support without displacement of !be construction equipment and the compaction hereinafter specified. Soft or yielding subgmde shall be corrected and made stable berore construction proceeds. 4.2 Central Mixing Plant The aggregate, cement and water shall be mixed in a pug mill as approved by !be Engineer/Architect. The plant shall be equipped with feed and metering devices !hat will add !be aggregate, cement and water into !be mixer in the specified quantities to produce a mixture . that will meet or exceed the mix design criteria as stated above. The aggregate and cement shall be ruixed sufficiently to prevent cement bans from forming when the mix water is added. The ruixing time shall be sufficient to assure an intimate. uniform mixture of aggregate, cement and water. The percentage of moisture in the aggregate, at the time of cement application shall be the amount !hat assures a uniform and intimate mixture of aggregate and cement during mixing opetlilions. It shall not exceed !be specified moisture content required for adequate compaction. Free """""" to !be plant shan be provided to the Engineer/Architect, his inspector and his designated Commeroial Testing Laboratory for CODStruction quality control. The mixture shall be hauled to !be paving area in trucks baving beds cleaned of deleterious material. 4.3 Placement and Compaction The mixture shall be placed on a moistened subgrade in a uniform layer by any approved method of spreading !hat will deposit the required quantity per lineal foot, without segregation, to produce a uniformly compacted base conforming to the grade and cross-section. Not more !han 30 minutes shall elapse between placement of CTB in adjacent lanes at any location except at longitudinal and transverse construction joints. No CTB mixture shall be placed when the subgmde is frozen or when the air temperature is less !han 40° F in the shade. The Engineer/Architect may allow placement when the temperature is 35° F and clearly rising. Compaction shall start as soon as possible after spreading. The elapsed time between !be addition of water to the CTB mixture and the start of compaction shall not exceed 60 minutes under normal conditions. The Engineer/Architect may alter this time if environmental conditions, such as temperature, huruidity or wind conditions would justify such a change. Laboratory tests may be required to verify changes in compaction time liruits. 152251940233 CTB-3 03194 At the start of compaction. the percentage of moisture in the mixture shall not be more than one percentage point below or two percentage points above the specified optimum moisture content. and shall be less than that quantity which will cause the Cement Treated Base mixture to become unstable during compaction and finishing. The specified optimum moisture content and density shall be determined in the field by a Moisture-Density Test. AASHTO T 134 or ASTM D 558. on representative samples of Cement Treated Base mixture obtained from the area prior to compaction. Prior to compaction, the mixture shall be in a loose condition for its fuIt depth. The loose mixture shall then be compacted uniformly to the specified density. During compaction operations. initial shaping may be required to obtain uniform compaction and required grade and cross-section. 4.4 Finishing When initial compaction is completed. the surface of the Cement Treated Base shall be shaped to the required lines, grades and cross-section. The moiature content of the surface material shaU be maintained at not less than its specified optimum moisture content during finishing operations. If any reshaping of the surface i. necessary. it shaU be lightly scarified to remove any compaction planes, scales or smooth surfaces left by equipment. Final compaction shall then be contioued until uniform and adequate density is obtained. The ern shall be uniformly compacted to a minimum of 96% of maximum density. Compaction and finishing shaU be done in such a manner as to produce. in not longer than two hours, a smooth, dense surface free of compaction planes, cracks, ridges, or loose material. 4.5 Cultiog After the ern bas been finished as specified herein, it shaJI be protected against drying for seven days by the application of a bituminous prime coat, or other acceptable methods. The finished ern shaU be kept continually moist until the curing material has been placed. The curing material shaU be applied as soon as possible, but not later than at the end of each day'. construction. If the bituminous cure is used: 4.5.1 Curing, Bituminous Prime Coat At the time the bituminous prime coat is applied. the Cement Treated Base surface shall be dense, shaJI be free of all loose and extraneous material and shaJI contain sufficient moisture to prevent excessive penetration of the bituminous material. The bituminous prime coat specified shaU be uniformly applied to the surface of the completed Cement Treated Base'at the rate of approximately 0.1 gallons per square yard with approved heating and distributing equipment. The exact rate and temperature of application for complete coverage without excess.ive runoff will be approved by the Engineerl Architect. ern4 03/94 Sbould it be oecessary for construction equipment or other tmffic to use the bitumioous-oovered surface before the bituminous prime coat has cured sufficiently to prevent 'pick-ups', sufficient graoular cover sball be applied before such use. The curing material shall be maintained by the Contractor during the seven day protection period so that all of the Cement Treated Base will be covered effectively during this period. Finisbed portions of Cement Treated Base that are tmveled 00 by equipment used in constructing an adjoining section shall be protected in such a manner as to prevent equipment from marring or damaging completed work. Cement Treated Base sball be protected for three days after its construction and until it has hardened. 4.5.2 Curing, Other Methods If curing i. achieved by methods other than Bituminous Prime Coat, the Eogineerl Architect must approve and curing must be performed in accordance with manufaclorer'. recommendations. 4.6 Construction Joints At the end of each day's construction a transverse construction joint sbaU be formed by cutting back into the completed work to form a fuJI depth vertical face. Cement Treated Base for large, wide areas shall be built in a series of parallel lanes of convenient length and width meeting the approval of the Eogineerl Architect. Longitudinal joints shall be formed at the edge ofeach day', construction by cutting back into the completed work to form a fuD depth vertical face free of loose or shattered materials. 4.7 Traffic Completed portions of Cement Treated Base may be opened immediately to ligbt traffic and to construction equipment provided the curing material or surface is ont impaired as specified in 4.5. The section may be opened to all tmffic after the three day curing period provided the Cement Treated Base has hardened sufficiently to prevent marring nr distorting of the surface by equipment or traffic. 4.8 Maintenance Tbe contractor shall be required within the limits of his contract to maintain the Cement Treated Base in good condition uotiI all work has been completed and accepted. Maintenance shall include immediate repairs of any defects that may occur. This work shall be done by the contractor at his own expense and repeated as often as may be necessary to keep the area continuously intact. Faulty work sbaD be corrected. Any low areas shall be remedied by replacing the material for the fuJI depth of treatment rather than by adding a thin layer of Cement Treated Base to the completed work. CfB-S 03194 5.0 CONSTRUCTION QUAUTY CONTROL PROGRAM To insure that the coosUuction phase of the Cement Treated Base is in accordance with the provisions of these specifications. the following quality control testiog program will be performed by a testing laboratory retained by the Contractor aod approved by the Engineerl Architect. 5.1 Establish the field moisture density curve in accordance with ASTM D 558 or AASHTO T 134 (Standard Compactive Effort). The results of this test performed on representative samples of CTB obtained from the area being processed at a time of about midway through the initial compaction phase will establish the optimum moisture content to be incorporated at the central mixing plant aod the maximum density will serve as a basis for establishing the density for acceptance. 5.2 The Field-Density of the compacted CTB mixture sbaIJ be determined by aoy of the foUowing: (1) Nuclear Method ASTM D 2922. (2) Saod Cone Method ASTM D 1556, (3) Water BaUoon Method ASTM D 2167. 5.3 Where strength of Cement Treated Base material is specified. compliaoce sbaIJ be determined by testing a set of three unconfined cylinders molded from a representative sample of uncompacted Cement Treated Base material taken within one boor from the addition of mixlng water to the Cement Treated Base material. Strengths of Cement Treated Base material sbaIJ be determined by compressive tests at seven (7) days in accordance with ASTM D 1833. Paragraph 5. "Test Specimens."
