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.

Battling Segregation in Asphalt Paving Roads Bridges

Dec 28, 2000  Segregation of hot-mix asphalt (HMA) is a. problem facing road builders. When the aggregate becomes. segregated prior to laydown, weak spots can form in the road. This will eventually lead to a quicker deterioration of the. road. Segregation can first occur at the plant, when the mix. material is loaded into the HMA storage silos.
