Research on Basalt Fiber Asphalt Concrete's High Temperature Performance

Abstract:

Conduct experimental study on high temperature performance about asphalt concrete with 6mm basalt fiber and ordinary asphalt concrete, 6mm fibers whose dosage is 0.12%0.15% and 0.17%, test method is high temperature rut test, test temperature is 60°C. The results show that basalt fiber can improve the high temperature properties of asphalt concrete substrate, in which basalt fiber asphalt concrete maximum dynamic stability value is almost 1.27 times that of ordinary asphalt concrete, permanent deformation is 34.02% lower than that of the ordinary asphalt concrete, improved the shear performance of asphalt concrete;for high temperature performance, the optimum amount of value about 6mm basalt fiber is 0.15% .
