Asphalt Product Manufacturers

The 567 Asphalt product manufacturers in the US produce asphalt and tar paving mixtures and blocks, asphalt shingles, roofing cements, and coatings. Asphalt paving mixtures and block account for more than half of industry revenue. Other key product categories include prepared asphalt and tar roofing and siding products and roofing asphalts and pitches, coatings, and cements.

Seasonality of Demand

The industry is subject to seasonal factors because road paving and roof installation activity occurs exclusively outdoors.

Material Cost Variability

The cost of asphalt, the primary material input to production for pavement and roofing products, is volatile and influenced by the trends in the global crude oil market.

Aug 6, 2026 - DOT Awards Funding for Highway, Bridge Projects

• According to Construction Dive, the US Department of Transportation awarded $1.73 billion in 2026 BUILD grants for 127 transportation projects, with $1.3 billion, or 77%, directed to roads and bridges. The funding, provided through the Infrastructure Investment and Jobs Act, also supports transit, ports, freight and passenger rail, truck parking, and aviation infrastructure. Demand far exceeded available funding, with nearly 1,200 applications requesting more than $14.5 billion. The emphasis on road and bridge improvements, including pavement upgrades and safety enhancements, could create additional bidding opportunities and strengthen project backlogs for the highway, street, and bridge construction industry.
• The total value of US construction put in place fell 0.1% in June 2026 compared to the prior month, according to the US Census Bureau. Economists polled by Reuters had expected US construction spending in June to rise by 0.2%. Residential construction spending dropped 0.3%, and nonresidential spending increased 0.1%. In the nonresidential buildings segment, growth was led by office projects (including data centers), which grew 2.7%. Transportation spending rose 0.7%, and amusement and recreation increased 0.6%. Communication and lodging spending each rose 0.5%. Healthcare spending rose 0.2%, while commercial and educational spending declined 1.2% and 0.3%, respectively. Construction spending related to manufacturing declined by 1.2% in June, while highway and street spending declined by 0.1%. Construction spending drives demand for asphalt products, including paving mixes and roofing materials.
• The third-quarter 2026 North American Engineering and Construction Outlook by FMI forecasts mixed performance in US building construction in 2026. Residential spending is essentially flat, as a 5% increase in improvements is offset by a 4% drop in single-family construction and a 1% decline in multifamily work. Nonresidential building spending contracts 5%, led by a 17% plunge in manufacturing, a 10% decline in warehouse construction, a 9% drop in lodging, and a 5% decrease in commercial work. Educational, public safety, and health care also edge lower, while office rises 2% because data center construction surges 21%. Amusement and recreation, transportation, and communication construction also notch modest gains. Highway and street construction expands 2% to $149 billion, supported by committed IIJA funds and project backlogs, although elevated costs limit the amount of work those funds can buy.
• According to Engineering News-Record, leaders of the House Transportation and Infrastructure Committee released a roughly $580 billion proposal, the BUILD America 250 Act, to guide federal transportation investment through fiscal 2031 after the 2021 Infrastructure Investment and Jobs Act (IIJA) expires. The bill emphasizes formula funding, with more than 90% of highway funds distributed that way, aiming to speed project delivery and give states greater flexibility. Industry groups support the predictability but question whether it preserves IIJA-era funding certainty. About $474.4 billion would come from the Highway Trust Fund authority, while $106 billion would rely on future appropriations, according to analysis by law firm Holland & Knight. The proposal would also eliminate some climate programs, add fees on electric vehicles, and raise review thresholds to streamline approvals, while economists caution that private financing cannot replace sustained federal spending.
