Study on the pavement performance test of SMA-13 bituminous mixture containing basalt fibers

For the mix proportion design of bituminous mixture, gap graded SMA-13 is selected and 4‰ of basalt fiber is added to it. Moreover, its pavement performance is compared with that of the ordinary SMA-13 bituminous mixture with the same amount of lignin fiber, so as to study the effect of the basalt fiber on the pavement performance of the SMA-13 bituminous mixture. The test results show that compared with the ordinary SMA-13 asphalt mixture, the bitumen aggregate ratio of the SMA-13 bituminous mixture with basalt fiber is reduced, and the high-temperature stability and low-temperature crack resistance are improved, while the water stability is improved to a limited extent.
