Plant Ops — Binder Price Index Adjustment
Binder Price Index Adjustment for asphalt plant management.
Asphalt-cement price adjustment clauses keep oil-price risk out of unit bids — both directions. The deadband is the contractor's retained risk; everything beyond it settles monthly against the index. Estimators who skip this clause price phantom risk into every tonne.
Formula
Note: Paving estimates only — the project mix design, agency specification and the plant's QC data govern. Temperature models are simplified; verify with an infrared gun and density gauge on the mat.
