HMA will be accepted based on its conformance to the project job mix 41 formula (JMF). For the determination of a project JMF, the Contractor shall 42 submit to the Engineer, representative samples of the various aggregates � 43 and blend sand to be used along with the gradation data showing the 44 various aggregate stockpile averages and the proposed combining ratios 45 and the average gradation of the compieted mix. Based on this submittat 46 from the Contractor, the Engineer will determine the asphalt binder I47 content, arti-strip requirement, and ignition furnace correction factor in the 48 mix design process. Using the representative samples submitted and 49 proposed proportion of each, trial mix tests will be run to determine the I POA of Everelt FAWAT-03-039 Satelllle RaillBarge Transfcr Facility Final Port Revfew Droft , Phase 7:Pier Construct�on 58 75 March 2005
