Abstract

The invention provides an anti-freezing pavement sealing layer material and a preparation method thereof. The anti-freezing pavement sealing layer material is prepared from the following raw materials: emulsified asphalt, a filler, a mixed solution and organic silicon polyacrylic resin; the filler is prepared from the following raw materials: zinc oxide, zirconium dioxide and ferric chloride; andthe mixed solution is prepared from the following raw materials: acetylacetone, butyl acetate and cyclohexane. Through a large number of researches and tests, the results show that the anti-freezing emulsified asphalt sealing material produced by the invention can achieve the effects of melting snow and removing ice when being applied to pavement of asphalt pavements, and can significantly improveanti-icing performance and anti-skid performance of the pavements. Besides, the material can also form a compact waterproof layer on an asphalt pavement, so that water damage to the pavement is effectively prevented, an effect of sealing cracks of the pavement can be achieved, and a preventive maintenance effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of road materials, in particular to an anti-icing pavement, in particular to an anti-icing pavement sealing material and a preparation method thereof. Background technique [0002] Due to the advantages of convenient construction and maintenance and good driving stability, asphalt pavement has been widely popularized and applied in various grades of highways, and has gradually developed into the main structural form of highways in our country. However, under the influence of freezing rain and snowfall in winter, the asphalt pavement is prone to icing and other phenomena. The icing on the road surface not only has an adverse effect on driving, but also brings serious damage to the asphalt pavement, especially the "black ice" problem. Seriously endanger driving safety. Therefore, in view of the freezing problem of asphalt pavement in winter, the development of asphalt pavement sealing material with excellent ...
