Rheology has been applied in wide study area, including in asphalt material. Many researchers utilize Dynamic Shear Rheometer (DSR) to evaluate the effect of additional material in asphalt or asphalt mastic. However, there is limited study on the rheology of Phase Change Material (PCM) in asphalt mastic. This study prepared conventional mastic and PCM mastic to be tested in DSR. The purpose of this study is to evaluate the effect of PCM in asphalt mastic. The result showed that PCM increases the elastic properties but decreases the modulus except at 12 PCM. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
