| 摘 要： | 通过对掺H18的聚合物沥青和基质沥青分别进行热力学试验，并对试验结果进行对比分析，认为改性沥青在高温下表现出优良的性能；基质沥青在加入聚合物后，其低温性能出现退化；掺加10%热解油H18后得到的改性沥青，其低温抗裂性能得到提高；掺加聚合物后，会使沥青在低温下变得更脆，但是RPE-H18可以缓解聚合物改性沥青低温性能的下降。

| Abstract: | Through thermodynamic tests on polymer asphalt mixing with H18 and base the asphalt, the test results are compared and analyzed. The result shows that the modified asphalt exhibits superior perfor-mance under high temperature; after adding polymer, the low performance of matrix asphalt degraded;mixing with 10%pyrolysis oil H18, the low temperature cracking performance of modified asphalt is im-proved; after mixing the polymer, asphalt will become more brittle at low temperatures, but RPE-H18 can ease the low performance degradation of polymer modified asphalt. |
