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.

Pavement engineers have been producing long-lasting asphalt pavements since the 1930s. Research has shown that well-constructed and adequately designed flexible pavements can perform well for extended periods of time (Mahoney, 2001). Many of these pavements in the were the products of full-depth or deep strength asphalt pavement designs, and both design philosophies have been shown to provide adequate strength over extended life cycles (Newcomb et al, 2010).
Used for three decades to enhance asphalt pavement performance, polymer modified asphalt binder (PMA) offers superior performance benefits that every pavement owner desires.
Asphalt pavements are quick to construct and easy to maintain, which means safe, smooth surfaces with fewer delays for drivers.
