Wear-resistant noise-reduction micro-surfacing mixture doped with reinforced waste aggregate and preparation method of wear-resistant noise-reduction micro-surfacing mixture
The invention belongs to the technical field of asphalt pavement maintenance materials, and relates to a reinforced waste aggregate-doped wear-resistant noise-reduction micro-surfacing mixture and a preparation method thereof. The modified steel slag concrete is prepared from 46-72 parts of modified steel slag aggregate, 34-45 parts of finely treated mineral aggregate, 1-5 parts of a regenerant, 1-3 parts of rubber, 0.1-0.3 part of polypropylene fiber, 8-12 parts of SBR (Styrene Butadiene Rubber) modified emulsified asphalt or SBS (Styrene Butadiene Styrene) modified emulsified asphalt, 6-9 parts of water and 1-3 parts of cement. The modified steel slag aggregate is formed by carrying out aging treatment on 43-65 parts of steel slag and then spraying 3-7 parts of polysiloxane hydrophobic coating; the finely treated mineral aggregate is aggregate which is separated from the waste asphalt mixture and has the firmness of not more than 12% and the stone crushing value of not more than 26%. According to the invention, the wear resistance and the skid resistance of the micro-surfacing can be improved, and the water absorption and the asphalt doping amount of the micro-surfacing can be reduced while the aging treatment time is shortened, so that the cost of the micro-surfacing is reduced.
本发明属于沥青路面养护材料技术领域，涉及一种掺加固废集料耐磨降噪型微表处混合料及其制备方法。改性钢渣集料46～72份，精细化处置矿料34～45份，再生剂1～5份，橡胶1～3份，聚丙烯纤维0.1～0.3份，SBR改性乳化沥青或SBS改性乳化沥青8～12份，水6～9份，水泥1～3份；改性钢渣集料由43～65份钢渣经过陈化处理后再喷涂3～7份聚硅氧烷疏水涂层形成；精细化处置矿料是由废旧沥青混合料分离的坚固性不大于12％的、石料压碎值不大于26％的集料。本发明不仅能够能够增加微表处的耐磨耗性能和抗滑性能，而且能够陈化处理的时间的同时降低其吸水率和沥青掺加量，从而降低微表处的成本。
