Research on Basalt Fiber Asphalt Concrete's Low Temperature Performance
Conduct experimental study on low temperature performance about asphalt concrete with 6 mm basalt fiber and without basalt, 6 mm fibers whose dosage is 0.12%0.15% and 0.17%, test method is the indirect tensile test, test temperature is -10±0.5 °C. The results show that basalt fiber improved the strength and failure strain of asphalt concrete in low temperature damage, reduced the failure stiffness, in which the maximum increased value of breaking strength is 3.41%, the maximum increased value of failure strain is 38.83%, and the maximum reduced value of failure stiffness is 25.52%, obviously improved low temperature cracking resistance of asphalt concrete;for low temperature performance, the optimum amount of value about 6 mm basalt fiber is 0.15%.
