Abstract

The invention discloses an environment-friendly anti-freezing material and a method for preparing the same. The material mainly consists of formate, carbonate, citrate and binary carboxylate. The method for preparing the environment-friendly anti-freezing material includes steps: mixing the formate, the carbonate, the citrate and the binary carboxylate according to proportion, and stirring the formate, the carbonate, the citrate and the binary carboxylate for 10 to 30 minutes so that the formate, the carbonate, the citrate and the binary carboxylate are mixed uniformly to form mixture; spraying starch solution or sodium silicate solution with the mass ranging from 1% to 10% of that of the mixture into the mixture, simultaneously continuously stirring the solution and the mixture for 15 to 60 minutes, and leading generated particles out of a container; and drying and sieving the particles to obtain particles with the sizes ranging from 0.1mm to 5mm, and bagging and sealing the particles to obtain the environment-friendly anti-freezing material, wherein the concentration of the starch solution or the sodium silicate solution used as adhesive ranges from 1wt% to 2wt%. The anti-freezing material is added into an asphalt mixture to be laid on an upper surface layer of a pavement, various index performances of the pavement are stable, freezing of the pavement at the temperature ranging from 0 DEG C to minus 18 DEG C can be effectively prevented, the applicable temperature range is wide, sustainable time is long, a long-term benefit can be realized by means of one-step investment, winter pavement management and maintenance cost can be greatly reduced, and the material is environment-friendly and energy-saving.

Description

Technical field: [0001] The invention relates to a road construction material, in particular to an environment-friendly anti-freezing material for the upper layer of an expressway asphalt pavement and a preparation method thereof. Background technique: [0002] In most parts of my country, the climate is extremely cold in winter. When there is continuous low temperature or rain followed by snow, it is difficult to melt the snow and it is very difficult to remove it. What's more serious is that thick snow and slippery ice have caused serious consequences such as traffic jams, highway shutdowns, and airport closures. It can be seen that the problems caused by snow not only bring difficulties to people's lives, but also hinder the development of the economy and affect the normal operation of people's lives and the national economy. Although the traditional method of passively spreading chlorine-containing deicing agent for deicing and deicing can temporarily relieve traffic an...
