摘　　要：通过车辙试验和单轴压缩蠕变试验对比,分析了高聚物化学网构改性沥青混合料的高温稳定性能。试验结果表明,高聚物化学网构改性沥青工艺极大地提高了沥青的高温稳定性能,且比用同一基质沥青改性的SBS、PE改性沥青和国外某品牌改性沥青高温性能优越。Comparing rutting test and compression creep test, high temperature stabilization of polymer chemical network forming modified asphalt mixture is analyzed. Test results indicate that high temperature per formance of the asphalt, which is modified by the technology of asphalt in this paper, is improved obviously. Furthermore, it is superior to SBS and PE modified asphalt modified with the same base asphalt and a certain imported modified asphalt.
