Segregation in Hot-Mix Asphalt Pavements

摘要

This report presents recommended methods and specifications to detect and measure segregation of hot-mix asphalt (HMA) using infrared thermography or ROSAN, laser surface texture measurements. It will be of particular interest to materials and construction engineers in state highway agencies, as well as contractor personnel responsible for construction of HMA paving projects. Further, the report contains criteria for classifying segregation to rutting potential, loss of fatigue life, permeability, and several other performance-related HMA properties.
