Asphalt modifier for roads as well as preparation method and application of asphalt modifier
The invention belongs to the field of road pavement materials, and particularly relates to an asphalt modifier for roads as well as a preparation method and application thereof, and the asphalt modifier for the roads is prepared from a methyl styrene block copolymer, epoxy resin, alkyl polyoxyethylene ether, a toughening agent, high-density polyethylene and kerosene. Compared with the prior art, the invention has the following beneficial effects: by adding alkyl polyoxyethylene ether, high density polyethylene and mixing with the methyl styrene block copolymer, the epoxy resin and the flexibilizer, a plurality of components cooperate with each other, and the wet aggregate, the asphalt modifier for roads and sodium carboxymethyl cellulose cooperate with each other, the porosity of the material is finally reduced, and the wear resistance of the material is improved. The stability (including soaking stability) and the low-temperature splitting tensile strength are improved, so that the asphalt modifier for the road and the asphalt mixture have better application prospects in road construction.
本发明属于道路路面材料领域，具体涉及一种道路用沥青改性剂及其制备方法和应用，该道路用沥青改性剂，由甲基苯乙烯类嵌段共聚物、环氧树脂、烷基聚氧乙烯醚、增韧剂、高密度聚乙烯和煤油组成。相对于现有技术，本发明的有益效果为：通过加入烷基聚氧乙烯醚、高密度聚乙烯，与甲基苯乙烯类嵌段共聚物、环氧树脂、增韧剂混合，多种成分相互配合，而湿集料、道路用沥青改性剂、钠羧甲基纤维素相互协同，最终降低了材料的孔隙率，提高了稳定度(包括浸水稳定度)以及低温劈裂抗拉强度，使该道路用沥青改性剂以及沥青混合料在道路施工中具有更好的应用前景。
