改性沥青对OGFC混合料性能的影响研究

摘要

Based on the three types of modified asphalt mixture rutting test in high temperature,low temperature bending test,permeability test and performance test sliding,the paper analyzes mixed with agent types on mixture properties of impact.The results showed that： mixed agent types,mixture showed a greater difference in performance,proposed OGFC paved road in the future,the choice should be mixed with specific agent types.%通过对三种类型的改性沥青混合料进行高温车辙试验、低温弯曲试验、透水性试验以及抗滑性能试验,分析了外掺剂类型对混合料路用性能产生的影响。结果表明：外掺剂类型不同,混合料的路用性能表现出较大差异;建议在铺筑OGFC路面时,要有针对性的选择外掺剂类型。
