Steel slag permeable asphalt mixture and preparation method thereof
The invention belongs to the technical field of road construction materials, and particularly relates to a steel slag permeable asphalt mixture and a preparation method thereof. Comprising aggregate, filler and asphalt, the aggregate is single-grain graded steel slag, and the grain size of the single-grain graded steel slag is 4.75-9.5 mm. In the steel slag permeable asphalt mixture, the adhesion grade of steel slag aggregate-asphalt can reach 5, the stability is high, and the flow value is small, so that the compressive strength of the mixture with the grain composition is maximum, and the deformation quantity is minimum. According to a water stability test, the residual stability can reach 90.68%, the Marshall stability can reach 9.12 kN, the dynamic stability value can reach 6350 times/mm, the volume expansion rate can reach 0.49%, and the permeability coefficient can reach 60.61 ml/s.
本发明属于公路建设材料技术领域，具体涉及一种钢渣透水沥青混料及其制备方法。包括集料、填料和沥青，所述集料为单颗粒级配钢渣，单颗粒级配钢渣的粒径为4.75mm‑9.5mm。该钢渣透水沥青混合料中，钢渣集料‑沥青粘附等级可以达到5，稳定度大且流值小，说明该颗粒级配的混合料的抗压强度最大并且形变量最小。其中，水稳定性试验其残留稳定度可以达到90.68％，马歇尔稳定度可以达到9.12kN和动稳定度值可以达到6350次/mm，体积膨胀率可以达到0.49％，透水系数可以达到60.61ml/s。
