The Federal Highway Administration (FHWA) recently released a new video series titled, "Asphalt Pavement Principles". This series focuses on key aspects of asphalt pavement design and construction. Listed below is additional information on each as a well as links to view the videos.
Density and Durability
Density is an important factor in making asphalt pavements more durable. This video presents several keys to achieving proper asphalt pavement density, as well as new technologies that are moving the industry forward.

Long-Life Pavements, traditionally referred to as Perpetual Pavements, are multi-layer designs built from the bottom up, with each layer engineered to maximize pavement life. With this approach, asphalt roads can be built with a structure that lasts many decades with only routine surface renewal and maintenance required, making it an ideal choice.
