春风塔河沥青与克拉玛依沥青及其混合料路用性能对比分析
|
摘要
根据国家"十三五"交通投资建设计划,新疆正处于公路大建设期,对沥青需求量大。但优质重交道路沥青产量不足,严重制约了新疆高速公路沥青路面建设。经研究发现,春风稠油减渣与塔河稠油减渣具有性能互补性,将2种减渣调和复配后,其性能优于现有的重交沥青性能指标。通过对比分析同标号下春风塔河沥青与克拉玛依沥青性能指标,得出春风塔河70A沥青高温性能优于克拉玛依70A沥青;通过对比分析同等条件下的沥青混合料技术性能指标,得出春风塔河沥青同样具有较好的高温抗车辙、低温抗裂性能,并将春风塔河沥青首次应用于新疆沥青路面高温抗车辙区重载交通道路,且通过检测试验段铺筑情况,验证了春风塔河沥青及其混合料具有良好的路用性能,能延长沥青路面使用寿命,同时也解决了新疆优质沥青供不应求的现状。
According to the Thirteen Five-Year Plan for traffic construction investment,Xinjiang is in the highway construction period,the demand for asphalt is high.However,the production of high quality heavy traffic asphalt is insufficient,which seriously restricts the construction of asphalt pavement of expressway in Xinjiang.It is found that Chunfeng heavy oil slag reduction and Tahe heavy oil slag reduction are complementary in performance,and the performance of the two slag reduction blending is better than that of the existing heavy traffic asphalt.In this paper,the performance indexes of Chunfeng Tahe asphalt and Karamay asphalt under the same grade are compared and analyzed,and it is concluded that the high temperature performance of Chunfeng 70A asphaltis better than that of Karamay 70A asphalt.Secondly,the technical performance indexes asphalt mixture under the same conditions are compared and analyzed,and it is concluded that Chunfeng Tahe asphalt also has good high temperature rut-resistance performanceand low temperature anti-cracking performance.Chunfeng Tahe asphalt was first applied to the heavy traffic road in the high temperature anti-rutting zone of asphalt pavement in Xinjiang.Through the detection of the test section,it is proved that Chunfeng Tahe asphalt and its mixture have good pavement performance,which makes the service life of asphalt pavement longer,and also can solve the present situation that the high quality asphalt in Xinjiang is in short supply.
