Once the design aggregate structure <br /> and asphalt binder content have been determined, the Contractor shall submit <br /> the HMA mix design on DOT form 350-042 demonstrating the design meets <br /> ' the requirements of Sections 9-03.8(2) and 9-03.8(6). HMA accepted by <br /> nonstatistical evaluation requires a mix design verification. For HMA <br /> accepted by commercial evaluation only the first page of DOT form 350-042 <br /> and the percent of asphalt binder is required. In no case shall the paving <br /> begin before the determination of anti-strip requirements has been made. <br /> Anti-strip requirements will be determined by: <br /> a. Testing by WSDOT in accordance with TM 718. <br /> b. Testing by Contractor in accordance with WSDOT TM 718. <br /> c. Historical aggregate source ant-strip use provided by WDOT. <br /> ' The mix design will be the initial Job Mix Formula (JMF) for the HMA being <br /> produced. Any additional adjustments to the JMF will require the approval of <br /> the Project Engineer and may be made per Section 9-03.8(7). <br /> 5-04.3(7)A2 Nonstatistical and Commercial Evaluation <br /> Delete this section and replace it with the following; <br /> 5-04.3(7)A2 Nonstatistical and Commercial Evaluation <br /> Mix designs for HMA accepted by Nonstatistical or Commercial <br /> evaluation shall; <br /> 1. Be submitted to the Project Engineer on WSDOT Form 350-042 <br /> ' 2. Have the aggregate structure and asphalt binder content <br /> determined in accordance with WSDOT Standard Operating <br /> Procedure 732 and meet the requirements of Sections 9-03.8(2) <br /> and 9-03.8(6). <br /> 3. Have anti-strip requirements, if any, for the proposed mix design <br /> determined in accordance with WSDOT Test Method T 718 or <br /> based on historic anti-strip and aggregate source compatibility <br /> from WSDOT lab testing.
