As the spring paving season gets underway across the United States, asphalt contractors are facing an unprecedented market environment. The conflict between the United States and Iran that began on February 28, 2026, has triggered what the International Energy Agency (IEA) calls the largest oil supply disruption in recorded history. For asphalt contractors, this is not an abstract geopolitical event. It is a direct threat to material pricing, project margins, and the viability of bids submitted weeks or months ago. The closure of the Strait of Hormuz, through which roughly 20 percent of the world’s daily oil supply passes, has sent crude prices surging and created a chain reaction that will inevitably reach liquid asphalt binder pricing. Understanding how this disruption differs from past oil shocks, and what it means for the months ahead, is essential for every contractor preparing to pave this season. Everything You Need to Know About What You should consider before committing to material-intensive projects this year.
The Scale of the Supply Disruption
The numbers coming out of this conflict are staggering by any historical measure. Before the conflict began, Brent crude was trading at roughly $60 per barrel. Within weeks, it crossed the $100 mark and has already touched $120 during peak volatility. While September 2026 futures are currently stabilizing around $75 to $80, suggesting markets anticipate a relatively contained timeline, the present reality is that the industry is operating in a market that has already experienced a massive structural shock.
What Makes This Disruption Different
The 2022 Russia-Ukraine war removed roughly 10 percent of global oil supply from the market through sanctions. The current disruption is twice that size by every available measure. The IEA activated an emergency stockpile release of 400 million barrels, but the core problem is that the Strait of Hormuz closure physically blocks the supply from reaching the market rather than rerouting it through financial mechanisms.
The February 28 start date is eerily close to the February 24 start of the Russia-Ukraine war, and the parallels are worth examining closely because they provide the only reliable historical benchmark for what asphalt contractors can expect.
The 2022 Playbook
The Kansas Department of Transportation Asphalt Adjustment Price Index offers the clearest record of what happened last time. In January 2022, the index showed PG 64-22 binder at $496 per short ton. By August 2022, at the peak of summer paving activity, it had reached $774 per short ton. That represents a 56.1 percent increase over eight months. Many contractors will recall that prices remained above $600 per ton throughout most of 2023 before gradually declining.
The current March 2026 Kansas DOT index stands at $496 per short ton. The Georgia DOT index stands at $559 per short ton. Both figures reflect the pre-war marketplace and will almost certainly rise sharply when the April and May indexes are published. Contractors should not mistake the current published figures for the prices they will actually pay this summer.
Why This Shock Is Structurally Worse Than 2022
The magnitude of the disruption is only half the story. The 2026 crisis differs from 2022 in a critical structural way that removes the safety valve that helped absorb the earlier shock.
No Swing Producer Available
During the Russia-Ukraine crisis, the global oil market was able to reroute supply, draw down strategic reserves, and lean on spare production capacity held primarily by Saudi Arabia and the United Arab Emirates. That spare capacity absorbed a crucial portion of the market shock. Binder prices still rose dramatically, but the cushion existed.
In 2026, the Strait of Hormuz closure blocks those same producers from participating in the global market. The consulting firm Rapidan Energy described the situation bluntly: the conflict has simultaneously taken offline a historically high share of global supply and disrupted the primary holders of spare capacity. There is no swing producer positioned to step in. The market has no meaningful cushion.
Refinery Behavior Compounds the Problem
When crude prices spike, refineries face a strong financial incentive to shift their production configuration away from heavy residual fractions, which is where asphalt binder comes from, and toward higher-margin light fuels like gasoline and diesel. This is not theoretical. Marathon Petroleum executed this exact maneuver at its Martinez, California facility in 2022, cutting asphalt output by 40 percent after upgrading for light crude processing.
The same behavior could occur again, especially as the general public feels acute pain at the pump and political pressure mounts to prioritize fuel production. The result would be a squeeze on binder supply that operates independently of crude price movements, adding a second layer of upward pressure on asphalt material costs.
Price Scenarios for the 2026 Paving Season
Any projection of where binder prices might go requires transparency about what is known and what is not. The following scenarios are derived by scaling the verified 2022 Kansas DOT index price movements proportionally against the current magnitude of disruption. These are editorial estimates, not market forecasts. Actual prices will depend heavily on the duration of the conflict, reserve deployments, domestic production response, and refinery behavior.
Scenario Estimates for PG 64-22 Binder
| Scenario | Price Range Per Short Ton | Increase From March 2026 Baseline | Key Assumptions |
|---|---|---|---|
| Conservative | $750 to $800 | +51% to +61% | Short conflict resolving by Q2 2026. Strategic reserve releases hold the spike near 2022 peak levels. |
| Moderate (Most Likely) | $850 to $950 | +71% to +91% | Conflict extends into Q3 2026. No swing producer fills the gap. DOT index lags spot market by 60 to 90 days. |
| Aggressive | $1,000 to $1,100 | +100% to +121% | Conflict extends beyond Q3. Refinery conversion amplifies binder shortage independent of crude movement. |
For context, September crude futures trading around $80 per barrel suggest that financial markets anticipate a relatively short disruption. If that timeline holds, the conservative scenario becomes the most likely outcome, and the financial impact for contractors would closely resemble 2022. However, even that best-case scenario brings painful memories of a 56 percent price increase in a single paving season. If the conflict extends beyond Q2, the math will change dramatically.
Practical Steps for Asphalt Contractors
While no one can control the price of crude oil or the duration of geopolitical conflicts, contractors can take specific actions to protect their businesses during this period of extreme uncertainty. The following steps are based on lessons learned from the 2022 disruption and the structural differences of the current crisis.
Review Escalation Clause Protections
Contractors bidding work that will be completed later this summer or early fall are effectively bidding into an uncertain material cost environment. Any escalation clause protections, wherever available, have substantial real value in this market. During the 2022 Russia-Ukraine disruption, contractors operating under multi-year DOT contracts with escalation clauses absorbed approximately 60 percent of crude’s price surge. Spot market buyers absorbed approximately 85 percent. That 25-point gap represents real financial protection for DOT-contract work, and real exposure for everyone else.
Watch the April DOT Indexes
The March 2026 DOT indexes represent the last clean pre-war data point. The April indexes, due in approximately four to six weeks from the time of the conflict’s start, will be the first to signal how the disruptions are transmitting into actual supplier pricing. Contractors should monitor these indexes closely and adjust their bidding strategies accordingly.
Key indexes to watch include:
- Kansas DOT Asphalt Adjustment Price Index for Midwestern regional trends
- Georgia DOT Asphalt Cement Price Index for Southeastern market signals
- State-specific indexes in your operating region, as regional variations can be significant
Maximize Recycled Asphalt Pavement Usage
Recycled asphalt pavement (RAP) becomes a more compelling financial option when virgin binder prices rise. Currently, only 23 states permit RAP content above 25 percent in surface mixes. Contractors operating in states with more flexible RAP specifications have an immediate competitive advantage. Even in states with stricter limits, evaluating maximum allowable RAP content for each mix design is a low-cost strategy that can reduce exposure to rising binder prices.
Understand the Supply Chain Transmission Lag
During the 2022 disruption, the Bureau of Labor Statistics Producer Price Index data showed that asphalt at the refinery gate jumped 43.5 percent. However, by the time that shock reached paving contractors as processed mix, the PPI for paving mixtures registered a 16.7 percent increase for the same year. The supply chain absorbed roughly two-thirds of the raw price movement before it reached the jobsite.
However, that buffer held the way it did in 2022 because it was a largely sanctions-driven market event rather than a physical supply blockade. The current situation involves actual physical disruption of supply through the Strait of Hormuz, which may reduce the supply chain’s ability to absorb price shocks. The BLS PPI data for asphalt paving cement was most recently updated in January 2026 at an index value of 326.6, a significant jump from the December 2025 figure of 269.5. This suggests that refinery-gate prices were already moving upward before the conflict began.

The coming months will test the resilience of the asphalt contracting industry. The combination of a 20 percent supply disruption, the absence of a swing producer, and the potential for refinery conversion away from binder production creates a market environment unlike anything the industry has faced. Contractors who prepare now by reviewing contracts, monitoring indexes, maximizing RAP usage, and understanding the true lag between crude movements and binder prices will be in the strongest position to navigate what lies ahead.
