Abstract
"Current research examined the feasibility and efficiency of employing phase change materials (PCMs) in asphalt pavement materials to result in thermo-adaptive asphalt pavement. The PCM was introduced to the asphalt materials in three different scales, including asphalt binder, asphalt mastic, and asphalt mixture. After investigating asphalt at different scales, mix blending method was found as the easiest method without any complexity to mix asphalt binder with PCM. The testing results could reveal an improvement in the high temperature performance of asphalt binder without sacrificing the low temperature performance with the presence of PCM and Gilsonite. Also, introducing PCM to asphalt binder increased the specific heat capacity of asphalt binder which resulted in improving the thermal regulation of asphalt binder. In the next incorporation method, among eight types of composite phase change materials (CPCMs) developed in the lab, the composite of polyethylene glycol and diatomite was found as the efficient one regarding some defined criteria and rheological and thermal tests on mastic. In the mixture scale, it was found that CPCM incorporation increases the thermal regulation of asphalt mixture. The temperature of asphalt mixture was about 3.7 ֯C cooler than the control mixture, thanks to higher specific heat capacity of PCM-incorporated mixtures. The incorporation of PCM had a non-significant negative impact on the mechanical performance of the mixtures. Of course, based on the criteria defined for the Hamburg wheel tracking test (HWTT), it could pass the essential requirement. IDEAL shear rutting test (RT) and asphalt mixture performance tester (AMPT) verified HWTT results. Cracking resistance was also found slightly lower than control mixture"-- Abstract, p. iv
