Edgewater Creek Bridge Replacement November 2023 111 1 If a constituent is not measured in accordance with these Specifications, its individual 2 pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 3 4 5-04.3(10) HMA Compaction Acceptance 5 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 6 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 7 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 8 specified level of relative density. The specified level of relative density shall be a 9 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with 10 Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). 11 The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The 12 specified level of density attained will be determined by the evaluation of the density of 13 the pavement. The density of the pavement shall be determined in accordance with 14 WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of 15 the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using 16 cores to determine density. 17 18 Tests for the determination of the pavement density will be taken in accordance with the 19 required procedures for measurement by a nuclear density gauge or roadway cores after 20 completion of the finish rolling. 21 22 If the Contracting Agency uses a nuclear density gauge to determine density the test 23 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the 24 mix is placed and prior to opening to traffic. 25 26 Roadway cores for density may be obtained by either the Contracting Agency or the 27 Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches 28 minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by 29 the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. 30 31 If the Contract includes the Bid item “Roadway Core” the cores shall be obtained by the 32 Contractor in the presence of the Engineer on the same day the mix is placed and at 33 locations designated by the Engineer. If the Contract does not include the Bid item 34 “Roadway Core” the Contracting Agency will obtain the cores. 35 36 For a lot in progress with a CPF less than 0.75, a new lot will begin at the Contractor’s 37 request after the Engineer is satisfied that material conforming to the Specifications can 38 be produced. 39 40 HMA mixture accepted by commercial evaluation and HMA constructed under conditions 41 other than those listed above shall be compacted on the basis of a test point evaluation 42 of the compaction train. The test point evaluation shall be performed in accordance with 43 instructions from the Engineer. The number of passes with an approved compaction 44 train, required to attain the maximum test point density, shall be used on all subsequent 45 paving. 46 47
