摘要
论文研究钢渣粗集料取代玄武岩集料制备SMA-13玄武岩纤维沥青混合料的路用性能。结果表明:利用钢渣粗集料取代玄武岩集料制备的SMA-13沥青混合料,在最佳油石比下降0.4%的情况下,虽然空隙率增大,但其马歇尔强度、水稳定性能和高温稳定性能优于玄武岩集料SMA-13沥青混合料对应的性能。
The pavement performances of the SMA-13 basalt fibers asphalt concrete with the coarse aggregate replaced by the steel slag were studied.The results show that the SMA-13 basalt fibers asphalt concrete with the coarse aggregate replaced by the steel slag possess less asphalt-aggregate ratio which decreases 0.4%.Although the void ratio has increased,the Marshall stability,water stability and the high temperature stability of the SMA-13 basalt fibers asphalt concrete with the coarse aggregate replaced by the steel slag are all better than that of the asphalt concrete prepared by basalt.
