摘要
通过沥青常规试验、延时老化试验及红外光谱分析等试验对春风塔河90A(CHTH90A)沥青及克拉玛依90A(KL90A)沥青进行性能评价,并对其沥青混合料性能进行对比分析。结果表明:CHTH90A高温稳定性较好、感温性能小,其抵抗低温变形能力较弱;随着老化时间的增加,CHTH90A低温性能趋于稳定,高温性能变化较为显著。CHTH90A的高温性能优于KL90A,建议在新疆地区大力推广应用CHTH90A。
The performance of Chunfeng-tahe 90A(CHTH90A)asphalt and Karamay 90A(KL90A)asphalt are evaluated through asphalt routine test,delayed aging test and infrared spectroscopic analysis and other tests,and their asphalt mixture performance is compared and analyzed.The results show that:CHTH90A has good high temperature stability,low temperature sensitivity and weak resistance to low temperature deformation;with the increase of aging time,the low-temperature performance of CHTH90A tends to be stable,and the high-temperature performance changes significantly.The high temperature performance of CHTH90A is better than that of KL90A.It is suggested that CHTH90A can be widely popularized and applied in Xinjiang area.
