When appropriate, the special provisions for certain projects will contain a provision for
adjustment of the cost of bituminous material. This will be shown in Section 109 of the special
provisions.

The “initial cost” (IC), as the term is used in the special provisions, for bituminous material
used on projects on which bids are opened during the month of DECEMBER 2023 is $559.00 per ton and this value will also be deemed to be the “current price” (CP) for the month of DECEMBER 2023 for projects in construction.

Also, when included in the special provisions for certain projects, an adjustment to the
contractor’s monthly progress payment may be made when fluctuations in the price of diesel fuel exceed ± 15 percent of the “initial cost”. An adjustment, if applicable, will be made as specified in Section 109 of the special provisions.

The “initial cost” (IC), as the term is used in the special provisions, for diesel fuel for
projects on which bids are opened during the month of DECEMBER 2023 is $3.31 per gallon. This
value will also be deemed to be the “current price” (CP) for the month of NOVEMBER 2023 for projects in construction.
