Road Performance of Brucite Fiber Asphalt Concrete
As a new type of pavement material, brucite fiber asphalt concrete has been never studied at home and abroad. Laboratory experiments are made on the brucite fiber asphalt concrete. Effects of the dosage of the brucite fiber on the physical properties such as the bulk density, volume of air voids, voids filled with asphalt, voids in mineral aggregates, optimum asphalt content and the strength are also studied by the Marshall test. The contrast tests on road performance are made between the brucite fiber asphalt concrete and the ordinary asphalt concrete by low temperature bending test, wheel rutting test and water stability test. Test results show that addition of brucite fibers in asphalt concrete can change the physical properties significantly, especially the volume indexes and the strength. According to the Marshall test results, the optimum quantity of brucite fiber is about 0.4 wt.% of asphalt concrete. Based on the contrast test, the brucite fiber asphalt concrete is better than the ordinary asphalt concrete on the anti-crack properties in low temperature, the stability properties in high temperature and the stability properties in water.
