Aggregate | Washington Asphalt Pavement Association

In HMA, aggregates are combined with a asphalt binding medium to form a compound material. By weight, aggregate generally accounts for between 92 and 96 percent of HMA and makes up about 25 percent of the cost of an HMA pavement structure. Aggregate is also used by itself or with a stabilizer for base and subbase courses.
