Asphalt Pavement Principles: Density and Durability

More than 18 billion tons of asphalt pavement are in place on U.S. roads. Long-lasting asphalt pavements are the result of collaborative partnerships between researchers, manufacturers, paving contractors, and agencies. When striving to make asphalt pavements more durable, research and lessons learned show that density is an important factor. This video talks about several keys to achieving proper asphalt pavement density, as well as new technologies that are moving the asphalt industry forward.
