Abstract
In order to evaluate the effects of fiber type,content and asphalt content on the road performance of fiber-reinforced asphalt mixtures,the low-temperature bending test,high-temperature rutting test and freeze-thaw splitting test were used to study the AC-16 asphalt mixture without fiber and the three different types of fibers(basalt fiber,polyester fiber and carbon fiber)reinforced modified asphalt mixtures were tested.The fiber content in the asphalt mixture is 0.2%,0.3%,0.4%and 0.5%(based on the total weight of the asphalt mixture).The optimal asphalt content is selected and its value plus or minus 0.1%is used.The research results show that the asphalt mixture with 0.3%basalt fiber content has the best high-temperature rutting resistance and low-temperature crack resistance;the asphalt mixture with 0.4%carbon fiber content has the best water stability;reducing the amount of asphalt will not improve the performance of the mixture;when the amount of asphalt is increased,the road performance of carbon fiber reinforced asphalt mixture will be significantly improved.关键词
