It is an important research field to restrict the extreme temperature of pavement by using the robust thermal performance of phase change materials. In this study, diatomite, expanded perlite, and stearic acid were chosen to prepare compound phase change materials (CPCMs) for the fabrication of novel cooling asphalt pavement. The microtopography and characteristics of CPCMs were described by scanning electronic micro-scopy, Fourier transform infrared spectroscopy and X-ray diffraction. The thermal performance and stability were confirmed by thermogravimetric analysis and differential scanning ...
