<br />Fulton Street Pedestrian Bicycle Corridor PAGE 89 OF 114 CONTRACT <br />FEDERAL AID # TAP-0420(026) <br />WO #3785 September 6, 2024 <br /> <br />lot shall be evaluated in accordance with Section 1 -06.2 to determine the appropriate 1 <br />CPF. The commercial tolerance limits will be used in the calculation of the CPF and the 2 <br />maximum CPF shall be 1.00. When less than three sublots exist, backup samples of the 3 <br />existing sublots or samples from the street shall be tested to provide a minimum of three 4 <br />sets of results for evaluation. 5 <br /> 6 <br />For each lot of HMA mix produced and tested under Commercial Evaluation when the 7 <br />calculated CPF is less than 1.00, a Nonconforming Mix Factor (NCMF) will be 8 <br />determined. The NCMF equals the algebraic difference of CPF minus 1.00 multiplied by 9 <br />60 percent. The Job Mix Compliance Price Adjustment will be calculated as the product 10 <br />of the NCMF, the quantity of HMA in the lot in tons, and the unit Contract price per ton of 11 <br />mix. 12 <br /> 13 <br />If a constituent is not measured in accordance with these Specifications, its individual 14 <br />pay factor will be considered 1.00 in calculating the Composite Pay Factor (CPF). 15 <br /> 16 <br />5-04.3(10) HMA Compaction Acceptance 17 <br />HMA mixture accepted by nonstatistical evaluation that is used in traffic lanes, including 18 <br />lanes for intersections, ramps, truck climbing, weaving, and speed change, and having a 19 <br />specified compacted course thickness greater than 0.10 -foot, shall be compacted to a 20 <br />specified level of relative density. The specified level of relative density shall be a 21 <br />Composite Pay Factor (CPF) of not less than 0.75 when evaluated in accordance with 22 <br />Section 1-06.2, using a LSL of 91.0 (minimum of 91 percent of the maximum density). 23 <br />The maximum density shall be determined by WSDOT FOP for AASHTO T 729. The 24 <br />specified level of density attained will be determined by the evaluation of the density of 25 <br />the pavement. The density of the pavement shall be determined in accordance with 26 <br />WSDOT FOP for WAQTC TM 8, except that gauge correlation will be at the discretion of 27 <br />the Engineer, when using the nuclear density gauge and WSDOT SOP 736 when using 28 <br />cores to determine density. 29 <br /> 30 <br />Tests for the determination of the pavement density will be taken in accordance with the 31 <br />required procedures for measurement by a nuclear density gauge or roadway cores after 32 <br />completion of the finish rolling. 33 <br /> 34 <br />If the Contracting Agency uses a nuclear density gauge to determine density the test 35 <br />procedures FOP for WAQTC TM 8 and WSDOT SOP T 729 will be used on the day the 36 <br />mix is placed and prior to opening to traffic. 37 <br /> 38 <br />Roadway cores for density may be obtained by either the Contracting Agency or the 39 <br />Contractor in accordance with WSDOT SOP 734. The core diameter shall be 4 -inches 40 <br />minimum, unless otherwise approved by the Engineer. Roadway cores will be tested by 41 <br />the Contracting Agency in accordance with WSDOT FOP for AASHTO T 166. 42 <br /> 43 <br />If the Contract includes the Bid item “Roadway Core” the cores shall be obtained by the 44 <br />Contractor in the presence of the Engineer on the same day the mix is placed and at 45 <br />locations designated by the Engineer. If the Contract does not include the Bid item 46 <br />“Roadway Core” the Contracting Agency will obtain the cores. 47 <br /> 48
