After all, correctly identifying pavement problems and their causes is at the heart of our business. Below we have identified and pictured 13 specific distresses/failures any pavement Pavement Types | Washington Asphalt Pavement Association The most common type of flexible pavement surfacing in the U.S. is hot mix asphalt (HMA). Hot mix asphalt is known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen. For clarity, this Guide makes a conscious effort to consistently refer to this material as HMA.
The Class 1/2 inch HMA is the most commonly used design but the Class 3/8 inch mixes are gaining popularity since the advent of the Hamburg Wheel-Track Testing device (AASHTO Test Method T 324) as a reliable predictive test for pavement stability and stripping susceptibility.
