钢渣薄层罩面沥青混合料试验研究与工程应用

摘要:

研究了钢渣薄层罩面沥青混合料的路用性能并在实体道路工程中进行了应用。结果表明,钢渣强度和磨光值高,与沥青粘附性强,各项性能指标满足道路集料规范要求。以钢渣代替玄武岩集料制备的薄层罩面沥青混合料SMA-10和OGFC-5的马歇尔稳定度、水稳定性能及动稳定度等路用性能均满足规范要求,并表现出良好的抗变形、抗水损和耐久性能。钢渣薄层罩实体工程施工应用顺利,路面质量和应用效果良好。

Abstract:

The road performance of steel slag thin overlay asphalt mixture is studied and applied in road construction. The results show that the steel slag has high strength and polishing value, strong adhesion with asphalt, and all performances meet the requirements of road aggregate specification. The Marshall stability, water stability and dynamic stability of thin-layer asphalt mixture SMA-10 and OGFC-5 prepared with steel slag instead of basalt aggregate meet the specification requirements. The mixture shows good deformation resistance, water damage resistance and durability. The surface of construction use steel slag thin layer cover is smooth, and the pavement quality and application effect are good.
