| 摘 要： | 通过对SEAM改性沥青及其混合料进行一系列室内试验研究，包括不同掺量的SEAM改性沥青的技术性能试验及不同SEAM与沥青比例条件下的混合料车辙试验、低温和常温劈裂试验、冻融劈裂试验以及磨耗飞散试验，得出的试验结果表明：在超过一定掺量条件下，SEAM能改善沥青及混合料的高温性能，但对其低温性能和水稳定性改变不明显，说明SEAM沥青混合料的抗车辙能力强，是高温稳定性好的沥青路面材料。

| Abstract: | Through a series of laboratory tests of SEAM modified asphalt and its mixture including different content SEAM modified asphalt technical property tests, and asphalt mixture rutting test, low temperature and room temperature splitting test, freeze-thaw splitting test and abrasion test under different proportional relations between SEAM and asphalt, the results show that adding a certain amount of SEAM can increase the high temperature property of asphalt mixture, but its influence on low temperature property and water stability is unconspicuous. Therefore, SEAM asphalt mixture is an asphalt pavement material of strong anti-rutting property and good temperature stability. |
