Asphalt Pavement History

Asphalt Pavement History

Hot mix asphalt (HMA) pavements have existed in their present form, as a mixture of angular aggregates and asphalt binder,  since the beginning of the 20th century.  However, HMA pavement can trace its roots back to ancient Roman roads and beyond.

The first recorded use of asphalt by humans was by the Sumerians around 3,000 B.C.  Statues from that time period used asphalt as a binding substance for inlaying various shells, precious stones and pearls.  Other common ancient asphalt uses were preservation (for mummies), waterproofing (pitch on ship hulls), and cementing (used to join together bricks in Babylonia).  Around 1500 A.D., the Incas of Peru were using a composition similar to modern bituminous macadam to pave parts of their highway system.  In fact, asphalt is mentioned several times in the Book of Genesis (Baird 2002).
