Green high-viscosity and high-toughness asphalt modifier, modified asphalt, preparation method and concrete
The invention discloses a green high-viscosity and high-toughness asphalt modifier, modified asphalt, a preparation method and concrete, and relates to the technical field of asphalt concrete for road engineering. Wherein the asphalt modifier comprises 70-232 parts of a waste rubber and plastic mixture; 4 to 10 parts of a nano clay material; and 15-50 parts of a compatilizer. According to the invention, a secondary melt blending extrusion method is creatively adopted to prepare the asphalt modifier, the modified asphalt and the concrete, so that the layered nano clay material can be better stripped, and the problem that the nano clay material is difficult to disperse in a waste rubber-plastic-based material is solved; meanwhile, the compatibility between the waste rubber and plastic material and the asphalt is improved through the nano effect of the nano clay material, so that the comprehensive performance of the asphalt and the concrete thereof is improved. The asphalt modifier, the modified asphalt and the concrete provided by the invention have the characteristics of low cost, greenness, low carbon, good stability, wide application range, high comprehensive performance and the like, and the preparation process is simple and suitable for industrial production.
本发明公开一种绿色高黏韧沥青改性剂、改性沥青及制备方法与混凝土，涉及道路工程用沥青混凝土技术领域。其中沥青改性剂包括：废旧橡塑胶混合物70～232份；纳米黏土材料4～10份；相容剂15～50份。本发明创造性提出采用二次熔融共混挤出法制备所述沥青改性剂及改性沥青与混凝土，能更好地实现层状纳米黏土材料的剥离，解决纳米黏土材料在废旧橡塑基材料中难以分散的难题，同时通过纳米粘土材料的纳米效应改善废旧橡塑材料与沥青间相容性，从而提升沥青及其混凝土的综合性能。本发明提供的沥青改性剂及改性沥青与混凝土具有低成本、绿色低碳、稳定性好、应用范围广、综合性能高等特点，且制备工艺简单，适用于产业化生产。
