| 摘 要： | Phase change material modified asphalt is prepared by using PEG/activated carbon composite solid-solid phase change materials for asphalt modification. Phase change materials modified asphalt with different ratios are aged and treaded alterably at high or low temperature, and then its appearance is observed. The properties of the modified asphalt, such as ductility, softening point, etc., are tested by using electronic tensile testing machine and thermal mechanical analyzer. Experiments show that when the content of PEG/activated carbon phase change material is 20%, the ductility of modified asphalt is the best; when the content of phase change material is 15% to 20%, the softening point of modified asphalt is obviously improved.
