Effect of Solid-Solid Phase Change Material’s Direct Interaction on Physical and Rheological Properties of Asphalt

Asphalt pavement is a temperature−sensitive structure that prone to temperature-related diseases. Phase change material (PCM) an excellent candidate for mitigating these This paper looked into the effects of indirect composite shape-stabilized PCM incorporation on characteristics asphalt. The compatibility, physical properties, and rheological properties asphalt with various content before after aging were thoroughly investigated. No phase separation no chemical reaction occurred between improved addition PCM, high−temperature performance indexes while low−temperature decreased as process progressed. matrix SBS−modified was distinct. added improve when temperature higher than 52 °C, reduced has impact rutting factor high content. creep behavior PG grade both improved. implication it cannot increase thermoregulation without cost scarifying or mixture.
