Source: Kansas Department of Transportation Asphalt Adjustment Price Index, PG 64-22, non-modified. ksdot.gov. March 2026 is the last published data point and does not yet reflect post-Feb. 28 market conditions. State DOT indexes typically lag spot market by 30–90 days during rapid price movements.
Source: Georgia Department of Transportation Asphalt Cement Price Index, monthly prevailing price. dot.ga.gov. Prices had softened from the 2024 peak before the Iran war disruption began. April 2026 index will be the first data point to potentially reflect post-war market conditions.
Russia-Ukraine war began Feb. 24, 2022. Removed ~10% of global oil supply. Kansas binder peaked at $774/ton in Aug.–Sep. 2022, a 56.1% rise from the Jan. 2022 baseline of $496/ton. The 2026 Iran war removed ~20% of global supply (IEA) with no spare capacity available to offset it. Sources: Kansas DOT; Rapidan Energy Group; International Energy Agency.
Per short ton, PG 64-22 equivalent, unmodified. Polymer-modified binders (PMA) will track higher. Methodology: proportional scaling of verified Kansas DOT 2022 response (+56.1% for ~10% supply loss) against current ~20% supply disruption, adjusted for IEA strategic reserve deployment. March 2026 baseline: $496/ton (Kansas DOT index).
A monthly survey of actual supplier selling prices to state DOT contractors within a given state. Sets the baseline for price escalation clauses on eligible contracts. The Kansas and Georgia indexes used here are among the most reliable and consistently updated public data sources available for liquid asphalt pricing.
It is not a spot market price and it is not real-time. It does not capture what an unprotected buyer pays today. During rapid market movements, the index typically lags the spot market by 30 to 90 days. The March 2026 figures shown here do not yet reflect post-Feb. 28 market conditions.
Contractors operating under multi-year DOT contracts with escalation clauses absorbed approximately 60% of crude’s 2022 price surge. Spot market buyers absorbed approximately 85%. That 25-point gap represents real protection for DOT-contract work — and real exposure for private and municipal work without escalation provisions.

The conservative, moderate, and aggressive price scenarios on the Price Scenarios tab are the editors’ estimates. They are derived by proportional scaling of the verified 2022 Kansas DOT index response against the current disruption magnitude and are intended as a planning range, not a prediction. No proprietary commodity pricing data was used.
