160.03 Procedure
160.03.01 Fuel Price Adjustment
The Department will make monthly price adjustments for fuel usage for Items listed in Table 160.03.01-1. The Department will calculate fuel price adjustments based on the monthly pay quantities of listed Items using the fuel usage factors listed in Table 160.03.01-1. 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. If the as-built quantity of an Item listed in Table 160.03.01-1 differs from the sum of the quantities in the monthly Estimates and the as -built quantity cannot be readily distributed among the months that the Item liste d in Table 160.03.01-1 was constructed, then the Department will determine fuel price adjustment by distributing the difference in the same proportion as the Item’s monthly Estimate quantity is to the total of the Item’s monthly estimates.

The Department will calculate fuel price adjustment on a monthly basis using the following formula: F = (MF − BF) G Where: F = Fuel Price Adjustment MF = Monthly Fuel Price Index for work performed from the first day of the month to the last day of the month for the month prior to the estimate cutoff date. BF = Basic Fuel Price Index G = Gallons of Fuel for Price Adjustment The Department will post the monthly fuel price index every month on the Department’s website: http://www.state.nj.us/transportation/business/trnsport/PriceIndex.shtm. The basic fuel price index is the previous month’s fuel price index before receipt of bids. The Department will use the fuel price index for the month before the regular monthly estimate cutoff date as the Monthly Fuel Price Index for work performed in the previous calendar month. If the Monthly Fuel Price Index increases by 50 percent or more over the Basic Fuel Price Index, do not perform any work involving Items listed in Table 160.03.01-1 without written approval from the RE.
160.03.02 Asphalt Price Adjustment
The Department will make monthly price adjustments for asphalt binder usage. Th e Department will calculate asphalt price adjustments based on the quantities of Items containing asphalt binder constructed during a given month. 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 = Monthly Asphalt Price Index for work performed from the first day of the month to the last day of the month for the month prior to 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 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 suppliers serving the area in which the Project is located, and will be determined by the Department each month. The Department will post the monthly asphalt price index every month on the Department’s website
