Abstract

The invention discloses an anti-freezing asphalt pavement material which is characterized by being prepared from the following raw materials in parts by weight: 60-80 parts of asphalt, 10-20 parts ofvinyl-terminated fluorosilicone oil, 3-6 parts of 2-naphthylamine-3, 6, 8-trisulfonic acid, 2-3 parts of epoxy modified bis (2-hydroxyethyl) amino (trimethylol) methane, 5-10 parts of carboxylated butyl rubber, 4-8 parts of amino-terminated hyperbranched polybenzimidazole, 3-5 parts of pig hair fibers, 0.5-1.5 parts of graphene nanosheets and 2-4 parts of phosphorus pentoxide. The invention also provides a preparation method of the anti-freezing asphalt pavement material. The anti-freezing asphalt pavement material provided by the invention is better in comprehensive performance and performance stability, better in anti-freezing effect, excellent in anti-rutting performance, not easy to deform, long in service life and capable of effectively improving the transportation efficiency and traffic safety of roads.

Description

technical field [0001] The invention relates to the technical field of pavement materials, in particular to an antifreeze asphalt pavement material and a preparation method thereof. Background technique [0002] In recent years, with the advancement of science and technology and the integration of urban and rural areas, the scale of cities has continued to increase. Urban road construction has become an important link between cities and towns, and industry and agriculture. It is also the normative, scientific and sustainable development of urban planning. important manifestation. The road is the artery of the national economy and plays an inestimable role in the development of the entire national economy. It has very important strategic significance in improving people's living standards and consumption. However, snow and ice in winter seriously affect the transport efficiency and traffic safety of the road, and sometimes even lead to closed traffic. Therefore, it is imper...
