钢渣玻璃纤维沥青混凝土性能研究

Performance of steel slag glass fiber asphalt concrete

将钢渣和玻璃纤维两种材料加入到沥青混凝土中,通过马歇尔试验法确定钢渣沥青混凝土最佳油石比,并采用对比试验,分析了钢渣沥青混凝土路用性能,再添加不同含量的玻璃纤维,分析其对钢渣混凝土的影响。结果表明,在沥青混凝土中掺入钢渣,沥青混凝土低温抗裂性能有所下降,掺入适量的玻璃纤维可以弥补该性能的下降,其最佳玻璃纤维掺量为0.2%。

Glass fibers and waste steel slag are added into asphalt concrete so thatasphalt aggregate ratio of steel slag as. phalt concrete is obained by doing Marshall test and the road performance of steel slag asphalt concrete is analyzed. Then different content of glass fiber is added again into the steel slag asphalt concrete to study the effect of glass fiber on steel slag asphalt concrete. It is found that low temperature crack resistance of asphalt concrete decreases with the addi. tion of steel slag,and proper glass fiber can compensate for the decrease, and the best glass fiber content is 0.2%.
