Properties of SBS Modified Asphalt Containing Phase Change Materials
Publication: International Conference on Road and Airfield Pavement Technology 2023
ABSTRACT
Road temperature-regulating phase change materials (PCM) can reduce the impact of high temperatures on asphalt pavements in summer. In this study, a PCM/SBS-modified composite asphalt was produced by melt blending of paraffin/expanded graphite/high-density polyethylene composite-shaped phase change materials (PHDP) and SBS-modified asphalt. Then the physical property tests and rheological property tests were conducted. The result showed that compared to SBS-modified asphalt without PHDP, PHDP/SBS-modified composite asphalt had decreased consistency and temperature sensitivity, but increased low-temperature performance. The rotary viscosity, zero shear viscosity, and complex modulus of PHDP/SBS modified composite asphalt decreased with the increase of the content, but the phase angle was improved. Therefore, the deformation resistance of PHDP/SBS-modified composite asphalt was reduced but the fatigue performance was improved. Due to it containing polymeric structures, PHDP/SBS-modified composite asphalt still has good rutting resistance and elastic recovery ability at 64°C. This study can provide some reference value for the application of PCMs in high-performance pavement.
