The Asphalt Pavement Alliance (APA) and its Core Partners are experts in design, construction, and maintenance of asphalt pavements. To help ensure that the highest quality asphalt pavements are built across the United States’ 2.2 million miles of paved roads, the Alliance provides many free tools that have been developed for engineers and owners and are focused on proper pavement design, latest asphalt paving specifications, best practices, and news.
The APA also shares its Core Partner’s education and training opportunities, exhibits at tradeshows, and serves as a resource to engineers and owners on behalf of the asphalt industry. Learn more about our upcoming events.

This document defines thin asphalt overlays as dense graded mixtures placed less than 1 1/2 in. in thickness. Thin asphalt overlays placed for pavement preservation are functional overlays to extend the service life of the pavement and are not intended to add structural capacity.
To understand the performance, safety, health,
the environment, and economics when designing and building an asphalt pavement, engineers need lawmakers to fund research that evaluates the reuse of plastic waste in our nation’s pavement structures.
Asphalt pavements are quick to construct and easy to maintain, which means safe, smooth surfaces with fewer delays for drivers.
