Abstract
Asphalt pavement is repeatedly functioned by vehicle load and temperature after it′s opening to traffic. When reaching a certain degree, it will produce fatigue cracking. In order to analyze the anti-fa⁃tigue performance of asphalt concrete reinforced with different volume of basalt fiber, the dynamic shear rheological test and DSR scanning test of asphalt mortar with different volume of basalt fiber are imple⁃mented, and the bending fatigue test of asphalt mixture with different volume of fiber is implemented. The results show that basalt fiber can enhance the anti-fatigue performance of asphalt mortar and asphalt mix⁃ture, which increases with increasing fiber volume. It exists the optimal dosage influenced by mixing dis⁃persion. Strain and anti-fatigue life of asphalt mixture has good relation of double logarithm linear.关键词
