Segregation: causes and cures | Asphalt magazine

Segregation in a hot mix asphalt (HMA) mixture can be defined as the separation of the coarse aggregate particles in the mix from the rest of the mass. The segregation can take one of three forms—random, side-to-side or longitudinal, and truckload to truckload. Each type of segregation is caused by a different problem or problems.
