Preliminary Study on Asphalt Mortar Containing Shaped-Stabled Phase Change Material

Abstract:

The objective of this study is to investigate the preliminary feasibility on the utilization of shaped-stabled phase change materials (SSPCM) in asphalt concrete to control pavement high-temperature. A comparative study has been conducted on the properties of asphalt with and without SSPCM. The properties investigated include basic and rheological performance along with temperature-controlling effect of asphalt mortars. The results show that there exist stiffening and “temperature lag” effect for asphalt mortar containing SSPCM, which indicates that it may be promising to use SSPCM to reduce high-temperature of asphalt pavement.
