摘要
为对比分析不同混合料类型的钢渣沥青混凝土高温性能,选取AC-13C与SMA-13两种钢渣沥青混合料为研究对象,进行车辙试验,与几种普通沥青混合料的车辙试验进行对比研究,并对钢渣使用时应注意事项进行了研究。结果表明:两种类型的钢渣集料沥青混合料的动稳定度均高于玄武岩及石灰岩配制的沥青混合料,因此,钢渣对动稳定度的增加有明显的促进作用;钢渣应用于道路工程时,应对钢渣原料的膨胀性能进行准确测试,并控制4号细钢渣集料的用量。
In order to analyze the high temperature performance of steel slag mixture in different asphalt types,steel slag AC-13 C and SMA-13 asphalt mixture were selected as the research subjects.The wheel tracking test was performed and the test results of steel slag asphalt mixture were compared with those of normal asphalt mixture.The notes for steel slag use were studied as well.The test result shows that the dynamic stability of both types of steel slag asphalt mixture are higher than that of basalt and limestone asphalt mixture.As a result,steel slag will spark a boon in improving the dynamic stability.It is important to get accurate results of the expansion performance of steel slag when it is applied in road engineering.The amount of 4# fine steel slag aggregates should also be controlled.
