Asphalt pavement is everywhere – it accounts for roughly 93% (or 2.5 million miles) of America's paved roadways and interstates, but how much do we really know about it? Where does it come from? How is it made? This article gives you a small glimpse into the production process of asphalt pavement.
When you hear the word “asphalt”, you probably picture a smooth black concrete surface, but that is not the case. In its purest form, asphalt is a hydrocarbon mixture which is a byproduct derived from the waste material of oil refinement. During the production of asphalt cement, this hydrocarbon byproduct is heated to about 300° F, or until it has the consistency of tar. At this point, other elements such as crushed stone, sand, and gravel are mixed in to provide a solid, durable surface. When mixing is complete, the resulting product only contains about 5% asphalt and 95% crushed stone.
From there, the hot asphalt concrete is poured, flattened, and steamrolled to make the roads, parking lots, and highways that you drive on every day. Other common uses for asphalt include roofing shingles, waterproofing underground storage tanks, and improving the durability of certain dark paints and finishes.
