Key Takeaways
- In the United States, asphalt pavement accounts for about 94% of all roads by surface type (asphalt is the most common highway surface).
- In the United States, there are about 2.7 million centerline miles of highways (with 2.2 million miles of paved roads).
- U.S. Department of Transportation reported that, in 2020, there were 4.3 million miles of public roads in the United States (including 2.6 million miles of paved roads).
- The U.S. EPA reported that asphalt shingles make up about 5% by weight of municipal solid waste (as a major asphalt-related roofing waste stream).
- The U.S. EPA reported that asphalt shingles contain about 20% of the asphalt binder used in roofing (composition context).
- The U.S. EPA’s “Beneficial Use of Asphalt Shingles” program notes that shingles diverted from landfill can reduce emissions associated with disposal and new material production. (quantitative diversion noted in document).
- The United States OSHA reported that the asphalt roofing/cooking sector includes heat-related hazards; OSHA heat illness guidance targets temperatures above 80°F with increased risk (not asphalt paving-specific but asphalt-related).
- NIOSH reported that construction workers face risks including exposure to asphalt fume, and recommended controls for hot-mix asphalt workers. (quantified exposure limits in NIOSH docs).
- OSHA established the permissible exposure limit for asphalt fumes at 5 mg/m3 as an 8-hour TWA (historical OSHA limit for asphalt fume).
- Typical asphalt binder penetration grade is specified in units of 0.1 mm; for example, PG 64-22 indicates performance grade parameters (temperature and rutting).
- AASHTO M 320 defines “Performance-Graded Asphalt Binder” for PG 64-22 and similar.
- AASHTO R 35 provides practice for determining the stiffness of asphalt binders using dynamic shear rheometer (multiple values).
- U.S. asphalt plants and paving activity are regulated in part by air permits; many states regulate asphalt mixing facilities under PM and VOC emission limits (varies).
- In the U.S., the Asphalt Concrete Pavement is a major item in federal highway construction spending; federal-aid highway construction spending was about $60B in 2022 (varies).
- The U.S. Federal Highway Administration’s FAST Act (2016-2020) provided $305 billion for highways, and the IIJA provided additional funding.
Asphalt dominates US roads, producing billions tons, while recycling cuts emissions.
