摘　　要：利用风淬钢渣替代沥青混合料中玄武岩细集料,制备沥青混合料研究其对沥青混合料的高温稳定性、低温抗裂性、水稳定性等性能的影响,并通过SEM及X-CT等材料检测技术对试验结果进行分析。试验结果表明风淬钢渣替代细集料极大地降低了油石比,显著改善了低温性能及水稳性能,从而表明风淬钢渣可以替代细集料生产沥青混合料,为钢渣的处理提供了一条有效的途径,同时极大地降低了沥青混合料的生产成本。The air quench steel slag is selected as fine aggregate to prepare hituminous mixture in order to study its impact on the high temperature performance, the low temperature performance and the stability in the water, and the test results are analyzed by means of SEM and X--CT. The results show that air queneh steel slag being the fine--aggregate has significantly reduced the oil/gravel ratio and improve the low temperature performance and water thermal performance, which can indicate that it can be applied as a replacement of fine aggregate when producing the bituminous mixture. It provides a way of reusing of the steel slag and reducing the production cost of bituminous mixture.
