What Is Asphalt?

Asphalt is one of the most widely used paving materials in the United States, surfacing approximately 94% of U.S. roads and highways. Composed of roughly 95% aggregates, such as stone, sand, and gravel, and 5% asphalt cement binder, asphalt pavement delivers a durable, flexible, and cost-effective solution for a wide range of paving applications.
Asphalt is also the most recycled material in America, with more than 70 million tons of asphalt pavement recycled annually. This recyclability, combined with rapid construction timelines, makes asphalt a critical component of modern infrastructure.
