Abstract

The invention relates to a pavement snow melting and ice condensation resisting material of a sand-containing fog seal and a preparation method of the material. The material is mainly prepared from the following raw materials in parts by weight: 40-60 parts of matrix asphalt, 3-10 parts of a modifying agent, 5-15 parts of tackifying resin, 5-10 parts of a snow-melting agent, 2-5 parts of a hydrophobic agent, 20-30 parts of a diluent and 15-25 parts of fine sand. After being prepared by the preparation method, the material is sprayed onto various pavements, so that under the condition of lower temperature, no matter how thick the snow is, an unfrozen water layer is always formed between each pavement and the snow and people can quickly and conveniently clean the snow on the pavements and airport runways mechanically or artificially. The material not only has the characteristics of the sand-containing fog seal but also has the functions of melting snow and resisting ice condensation, hardly corrodes iron and steel, does not have adverse effects on concrete, has the function of waterproofing the pavements and also has the effects of effectively protecting the pavements, effectively preventing losses and reduction of pavement materials and prolonging the service lives of the pavements.

Description

(1) Technical field [0001] The invention belongs to a novel pavement maintenance material, in particular to a snow-melting anti-condensation ice-containing sand mist sealing layer material and a preparation method thereof. (2) Background technology [0002] In the cold winter, many highways and urban roads often suffer from ice and snow hazards, and when the snowfall is heavy, the road surface is basically in the state of ice and snow. Ice and snow greatly reduce the adhesion coefficient of the road surface, causing the car to skid, the braking distance is significantly extended, and even the brakes fail, and the direction is out of control, resulting in serious traffic accidents. Generally, the method of spraying deicing agent is used to reduce icing on the road surface and facilitate snow removal. The method of spreading deicing agent is a disposal measure after snow falls and freezes. It is not preventive and affects traffic. At the same time, most deicing agents are har...
