I 1 I 2 If a constituent is not measured in accordance with these Specifications, its individual pay 3 factor will be considered 1.00 in calculating the Composite Pay Factor(CPF). 4 5 5-04.3(9)C7 Mixture Nonstatistical Evaluation - Retests 6 The Contractor may request a sublot be retested. To request a retest, the Contractor shall 7 submit a written request within 7 calendar days after the specific test results have been 8 received. A split of the original acceptance sample will be retested. The split of the sample 9 will not be tested with the same tester that ran the original acceptance test. The sample will 10 be tested for a complete gradation analysis, asphalt binder content, and, at the option of the 11 agency, Va. The results of the retest will be used for the acceptance of the HMA in place of 12 the original sublot sample test results. The cost of testing will be deducted from any monies 13 due or that may come due the Contractor under the Contract at the rate of$500 per sample. , 14 15 5-04.3(9)D Mixture Acceptance—Commercial Evaluation 16 If sampled and tested, HMA produced under Commercial Evaluation and having all I 17 constituents falling within the tolerance limits of the job mix formula shall be accepted at the 18 unit Contract price with no further evaluation. When one or more constituents fall outside the 19 commercial tolerance limits in the Job Mix Formula shown in 5-04.3(9), the lot shall be 1 20 evaluated in accordance with Section 1-06.2 to determine the appropriate CPF. The 21 commercial tolerance limits will be used in the calculation of the CPF and the maximum CPF 22 shall be 1.00. When less than three sublots exist, backup samples of the existing sublots or 23 samples from the street shall be tested to provide a minimum of three sets of results for 24 evaluation. 25 I 26 For each lot of HMA mix produced and tested under Commercial Evaluation when the 27 calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be determined. 28 The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 60 percent. The 29 Job Mix Compliance Price Adjustment will be calculated as the product of the NCMF, the 30 quantity of HMA in the lot in tons, and the unit Contract price per ton of mix. 31 I 32 If a constituent is not measured in accordance with these Specifications, its individual pay 33 factor will be considered 1.00 in calculating the Composite Pay Factor(CPF). 34 I 35 5-04.3(10) HMA Compaction Acceptance 36 HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 37 lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 38 specified compacted course thickness greater than 0.10-foot, shall be compacted to a 39 specified level of relative density. The specified level of relative density shall be a Composite 40 Pay Factor(CPF) of not less than 0.75 when evaluated in accordance with Section 1-06.2, I 41 using a LSL of 91.0 (minimum of 91 percent of the maximum density). The maximum density 42 shall be determined by WSDOT FOP for AASHTO T 729. The specified level of density 43 attained will be determined by the evaluation of the density of the pavement. The density of 44 the pavement shall be determined in accordance with WSDOT FOP for WAQTC TM 8, 45 except that gauge correlation will be at the discretion of the Engineer, when using the 46 nuclear density gauge and WSDOT SOP 736 when using cores to determine density. 47 48 Tests for the determination of the pavement density will be taken in accordance with the 49 required procedures for measurement by a nuclear density gauge or roadway cores after I 50 completion of the finish rolling. 2020 PAVEMENT MAINTENANCE OVERLAY PAGE 56 OF 79 SPECIAL PROVISIONS WORK ORDER 3727 FEBRUARY 20,2020
