High temperature stability low-temperature crack resistance water stability and anti-fatigue performance were analyzed by rutting test low temperature bending test soggy Marshall test freezing-thawing cyclic split test and four-point blending fatigue test.The test results indicated that basalt fiber can improve the high temperature stability the low temperature crack resistance and anti-fatigue performance obviously but its influence to the water stability need to be studied deeply.Basalt fiber can improve the pavement performance of AC-13C asphalt mixture effectively and has better effectiveness in SBS modified asphal...
