HMA will be accepted based on its confortnance to the project job mix fortnula (JMF). For <br />the determination of a project JMF, the Contrac!c� shali submit to the Engineer, <br />representative samples of the various aggregates an� ;��and sand to be used along with the <br />gradation data showing the various aggregate stockpile averages and the proposed <br />combining ratios and the average gradation oi the completed mix. Based on this submittal <br />from the Contractor, the Engineer will detertnine the asphall binder content, anti-strip <br />reyuirement, and ignition fumace cortection factor in the mix design process. Using the <br />represenlative samples submitted and proposed proportion of each, trial mix tests will be <br />run to determine the percentage of asphalt binder, by weight, to be added. The JMF thus <br />established shall be changed only upon order of the Engineer. <br />The intermingling of HMA mixtures produced from more than one JMF is prohibited. Each <br />strip oi HMA pavement placed during a working shift shall confoRn to a single job mix <br />formula established for the class of HMA specified unless there is a need to make an <br />adjustment in the JMF. <br />No HMA shall be produced for use on the project until the amount of asphalt binder and <br />anti-strip additive to be added has been established. <br />2. Job Mix Formula — Statistical Acceptance <br />The average gradation of the completed HMA mix submitted by the Contractor in the mix <br />design proposal, as required in Gradation and the resulting Mix Design Recommendations, <br />shall be the JMF. Any change or adjustment of percentages in any constituent of the JMF <br />creates a new JMF. <br />3. Job Mix Formula Tolerances and Adjustments <br />Page 16 of 50 <br />
