fourteenth day of the month and continuing past midnight into the fifteenth day of the month will be included in period one for any price adjustments. Work continuing through midnight of the last day of the month into the first day of the next month will be included in period two. The Asphalt Price Adjustment will be separated between ashpalt binder grades PG 64S-22 and PG 64E-22. The price used for both the Basic and Monthly Price Indexes will be determined based on the performance grade of asphalt binder in the approved mix design for the asphalt mixture. Price adjustments may result in an increased payment to the Contractor for increases in the price index and may result in a reduction in payment for decreases in the price index. The Department will calculate the asphalt price adjustment by the following formula: A = (MA − BA)  T Where: A= Asphalt Price Adjustment MA = Asphalt Price Index for work performed in the time period immediately before the estimate cutoff date. BA = Basic Asphalt Price Index T= Tons of New Asphalt Binder1 1. The Department will determine the weight of asphalt binder for price adjustment by multiplying the percentage of new asphalt binder in the approved job mix formula by the weight of the item containing asphalt binder. If a Hot Mix Asphalt Item has a payment unit other than ton, the Department will apply an appropriate conversion factor to determine the number of tons of asphalt binder used. For Tack Coat, Prime Coat, MICRO SURFACING EMULSION, SLURRY SEAL EMULSION, and FOG SEAL SURFACE TREATMENT, the Department will calculate the weight of asphalt as follows: T= G  C  0.00428 C= Petroleum content of the product Use 100% for Tack Coat 64-22 and Tack Coat 64E-22 Use 60% for Polymer Modified Tack Coat, and all other emulsified asphalts G= Gallons furnished The constant 0.00428 is derived from the conversion factor of tons per gallon using 8.345 lbs/gallon for water and a factor of 1.025 for the specific gravity of asphalt binder. The Department will not calculate an asphalt price adjustment for FOG SEAL STRIP. The monthly asphalt price index, as determined by the Department, will be the average of quotations from

lt binder. The Department will not calculate an asphalt price adjustment for FOG SEAL STRIP. The monthly asphalt price index, as determined by the Department, will be the average of quotations from suppliers serving the area in which the Project is located, and will be determined by the Department. The Department will post the asphalt price index every month on the Department’s website: https://www.state.nj.us/transportation/business/aashtoware/PriceIndex.shtm. The Basic Asphalt Price Index will be the Index which is listed for the month prior to the receipt of bids. If the month prior to the receipt of bids has two Indexes, the Index in effect for the first day of the month will govern for the Basic Asphalt Price Index. The Monthly Asphalt Price Index will be that for the month that the work is constructed in. If work is constructed over the course of two or more months for a particular pay estimate, then multiple Monthly Indexes will be used corresponding to the date that the work was performed. If the Asphalt Price Index increases 50 percent or more over the basic asphalt price index, do not perform work on Items containing asphalt binder without written approval from the RE.
