How Asphalt Is Produced

Asphalt is a material made from dried crushed rock and petroleum compounds. It’s a natural and 100-percent recyclable material that is useful in a vast range of applications, from paving roadways and basketball courts to lining reservoirs and fish hatcheries.

Asphalt plants mix and heat the petroleum compounds and crushed rock. The asphalt is then loaded immediately onto trucks for delivery to construction sites or kept in storage silos.
