Photodegradation of hot-mix asphalt - ScienceDirect

Nov 01, 2008  Thermal analysis. The result of the thermal analysis of the hot-mix asphalt showed that the hot-mix asphalt had an initial increase in mass and then a mass loss of 1.29% at 380 °C. The mass loss was more significant at 400 °C and higher temperatures. Two exothermic events were identified at 361.6 °C, and 499.5 °C.
