Infrared system detects thermal segregation Asphalt

Thermal segregation is defined as temperature differences in the hot mix asphalt (HMA) mat as it is placed and is a potential cause of premature failure in asphalt roads. It can cause a significant reduction in pavement life due to low density from cold spots in the HMA mat. In the past, problems related to thermal segregation only became ...
