Abstract
In order to discuss the effect of the basalt fiber on reinforcing pavement performance of asphalt mixtures, the optimum dosage of asphalt and fibers were studied by the method of Marshall test and rut test firstly. Then pavement performances of basalt fiber-modified asphalt mixtures were investigated through tests of high temperature stability, water stability and low temperature crack resistance, and compared with that of polyester fiber, xylogen fiber and control mixture. The testing results showed that the pavement performance of fiber-modified asphalt mixture are improved and optimized comparing with control asphalt mixture, and the performance of basalt fiber-modified asphalt mixture with best composition were excelled than those of polyester fiber and xylogen fiber.
