摘要
利用PEG/活性炭固-固相变材料对沥青进行改性,制备出相变材料改性沥青,用热机械分析(TMA)测定改性沥青的熔点。结果表明,PEG/活性炭固-固相变材料可以有效地改善沥青的熔点,随着相变材料的加入量的增大。
Asphalt was modified by using PEG/activated carbon solid - solid phase change materials, and phase change materials modified asphalt was prepared, and the melting point of the modified asphalt was determined with thermo - mechanical analysis （TMA）. The results showed the melting point of asphalt can be improved by PEG/activated carbon phase change materials, and with the increase of the addition amount of the phase change material, the mehing point of the modified asphalt was increased.
