Resources

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 Design

The Alliance offers many free tools and resources to help you design innovative, long-lasting asphalt pavements of the highest quality.

PAVEXpress

PAVExpress is a free web-based pavement design tool available for use by local agencies, engineers, and architects who need a reliable way to quickly determine the necessary pavement thickness for a given section of roadway or project. PAVEXpress creates technically sound pavement structural designs for both asphalt and concrete pavements based on widely accepted industry standards from the American Association of State Highway Transportation Officials (AASHTO).

PAVEInstruct

The PAVEInstruct learning module is a web-based pavement design education system with video instruction by leading industry experts. PAVEInstruct accompanies PAVEXpress, a web-based software created to design flexible and rigid pavements using AASHTO 93/98. The education modules within PAVEInstruct correlate with the design modules in PAVEXpress and provide technically sound pavement design and instruction.

Perpetual Pavement

"Perpetual Pavement" is the name coined to describe a 3-layer, flexible pavement design and construction concept. Application of the concept produces a deep-strength asphalt pavement that can resist structural fatigue distress for a long time (at least 50 years) and, thus, results in a long-lived pavement.

Commercial Applications

Commercial pavement applications commonly use asphalt. Asphalt pavements are versatile, long-lasting, and sustainable. Owners find that asphalt pavements are smooth, aesthetically pleasing, and are easily maintained.

Private Market Applications

Parking lots are the gateway to which all employees, customers, and visitors view upon arrival. As a first impression, it's important to welcome pedestrians with a well-maintained, smooth parking lot. Asphalt parking lots are the superior material of choice for parking lots due to their speed of construction, sustainability, and cost. When designing an asphalt parking lot important considerations are: traffic, subgrade, and drainage.
