I 1 1 If sampled and tested, HMA produced under Commercial Evaluation and having all 2 constituents falling within the tolerance limits of the job mix formula shall be accepted at 3 the unit Contract price with no further evaluation. When one or more constituents fall I 4 outside the commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the 5 lot shall be evaluated in accordance with Section 1-06.2 to determine the appropriate 6 CPF. The commercial tolerance limits will be used in the calculation of the CPF and the 7 maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 8 existing sublots or samples from the street shall be tested to provide a minimum of three 9 sets of results for evaluation. 1 10 11 For each lot of HMA mix produced and tested under Commercial Evaluation when the 12 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be 13 determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 14 60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product 15 of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of I 16 mix. 17 18 If a constituent is not measured in accordance with these Specifications, its individual I19 pay factor will be considered 1.00 in calculating the Composite Pay Factor(CPF). 20 I 21 5-04.3(10) HMA Compaction Acceptance 22 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 23 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a I 24 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 25 specified level of relative density. The specified level of relative density shall be a 26 Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with I 27 Section 1-06.2, using a LSL of 92.0 (minimum of 92 percent of the maximum density). 28 The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The 29 specified level of density attained will be determined by the evaluation of the density of 30 the pavement. The density of the pavement shall be determined in accordance with I 31 WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of 32 the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using 33 cores to determine density. 1 34 35 Tests for the determination of the pavement density will be taken in accordance with the I 36 required procedures for measurement by a nuclear density gauge or roadway cores after 37 completion of the finish rolling. 38 111 39 If the Contracting Agency uses a nuclear density gauge to determine density the test 40 procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the 41 mix is placed and prior to opening to traffic. I 42 43 Roadway cores for density may be obtained by either the Contracting Agency or the 44 Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4-inches I 45 minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by 46 the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. 47 i N. BROADWAY TRANSIT IMPROVEMENT PROJECT ISTATE FUND#GCB2316;COE WO#3644 87 August 8, 2018
