About

Asphalt is one of the world’s most-used yet least-understood substances. It’s been used continuously for at least a couple thousand years. And in spite of improvements through modern technology, we still haven’t found anything that can replace asphalt paving for day-to-day applications. The asphalt used for road paving contains gravel, sand, oil-based liquid asphalt, along with some other constituents. Asphalt paving is flexible and durable, which are its most important qualities. Day after day, year after year, asphalt expands and contracts along with hot and cold weather, and it provides a smooth, safe, high-traction surface for vehicles’ tires and pedestrians’ shoes alike.
