Steel slag powder modified ardealite-based filler, preparation method thereof, asphalt mixture and preparation method thereof
According to the invention, the chemical composition of the industrial waste residue phosphogypsum is utilized, and a certain amount of steel slag powder and limestone mineral powder are added synergistically, so that the steel slag powder modified phosphogypsum-based filler for replacing mineral powder to be doped into an asphalt mixture is obtained, and the mechanical properties of the asphalt mixture are effectively ensured; the steel slag powder modified ardealite-based filler prepared by the invention is used as a filler, so that the overall strength of an asphalt mixture prepared from the steel slag powder modified ardealite-based filler can be ensured, the structural stability of an asphalt pavement is ensured, the residual stability and the freeze-thaw splitting strength ratio of the asphalt mixture are improved, the water damage resistance of the asphalt pavement can be effectively improved, and the service life of the asphalt pavement is prolonged. Moreover, the stability and dynamic stability of the asphalt mixture are improved, and the high-temperature deformation resistance of an asphalt pavement can be effectively improved.
本发明利用工业废渣磷石膏自身的化学组成，协同加入一定量的钢渣粉和石灰石矿粉，得到用来替代矿粉掺入沥青混合料中的钢渣粉改性磷石膏基填料，有效保证了沥青混合料的力学性能；采用本发明制备的钢渣粉改性磷石膏基填料作为填料，可以保证由其制备的沥青混合料的整体强度，从而保证沥青路面的结构稳定性，并且提高了所述沥青混合料的残留稳定度和冻融劈裂强度比，可以有效改善沥青路面的抗水损坏能力，而且提高了所述沥青混合料的稳定度和动稳定度，可以有效改善沥青路面的抗高温变形能力。
