摘　　要：通过两种沥青混合料的劈裂试验、冻融劈裂试验,浸水马歇尔、低温弯曲及车辙试验,以及在新农至西中岛公路(交流岛至通水沟)工程试验路的观测情况,分析了奥米无机纤维沥青混合料在季节性冻土及多年冻土地区的适应性。研究得出,在相同沥青含量下,掺入奥米无机纤维的沥青混合料的水稳定性、低温稳定性和高温稳定性均有明显提高。结果表明,奥米无机纤维沥青混合料在冻土地区公路建设中有良好的使用价值。According to the slitting test,freeze-thaw splitting test,immersion Marshall test,low-temperature bending and rutting test of two asphalt mixtures,and the viewing result of engineering test road of Xinnong – Xizhongdao Highway(Jiaoliudao – Tongshuigou),the article analyzes the adaptability of Naomi inorganic fiber asphalt mixture in the seasonal frozen soil and permafrost regions.The study gives that the water stability,low-temperature stability and high-temperature stability of asphalt mixtures added with Naomi inorganic fiber are all obviously improved under the same asphalt contents.The result shows that the Naomi inorganic fiber asphalt mixture has the good using value in the highway construction of the frozen soil regions.
