Controlled preparation and low-temperature performance of solid-solid phase change materials for asphalt pavements
Source abstract
Abstract
Solid-solid phase change materials (SSPCMs) exhibit great potential for improving the low-temperature performance (LTP) of asphalt pavements. In this study, a series of SSPCMs suitable for low-temperature environments were synthesized and optimized. Then, the SSPCMs were incorporated into asphalt, and their effects on the road performance, temperature regulation performance (TRP), and LTP of asphalt were investigated. The results indicate that the thermal storage properties of SSPCMs can be precisely controlled by adjusting the soft segment mass fraction. The freezing temperature index based on dynamic mechanical analysis (DMA) is recommended to evaluate the LTP of SSPCMs modified asphalt (SPMA), and SSPCMs with a soft segment mass fraction of 75% can reduce the freezing temperature by 10.13°C. SSPCMs improve the LTP of asphalt through their superior mechanical properties and thermal storage properties.
