Ice condensation resistant ultra-thin wearing course pavement and preparation method thereof

Abstract

The invention discloses an ice condensation resistant ultra-thin wearing course pavement and a preparation method thereof. The ice condensation resistant ultra-thin wearing course pavement is prepared from the following raw materials in parts by weight: 15-17 parts of 10-15 mm gravels, 14-16 parts of 5-10 mm gravels, 11-13 parts of stone chips of which the particle size is smaller than 3 mm, 3-5 parts of ice condensation resistant agents, 2.2-2.6 parts of modified asphalt, and 1.1-1.4 parts of polymer modified emulsified asphalt, wherein the content of sodium chloride in the ice condensation resistant agents is 50-60%, and the solid content of the polymer modified emulsified asphalt is greater than or equal to 65%. According to the invention, ice condensation resistant ultra-thin wearing courses are paved on the pavement, so that the ice point of water in the surface of the pavement is reduced, snow accumulation and icing on the pavement are delayed, a new solution is put forward for solving the problem of the congelation of the pavement in winter is restrained, and safe running on the pavement is ensured.

Description

technical field [0001] The invention relates to the technical field of pavement pavement, in particular to an anti-icing ultra-thin wear layer pavement and a preparation method thereof. Background technique [0002] Snow and icing on the road affects the skid resistance of the road surface, hindering the smooth flow of the road and driving safety, which has become a difficult problem for the road management department. Therefore, the research and development of scientific and effective road surface ice and snow suppression technology has become the focus of road workers in various countries. [0003] At present, pavement deicing can be roughly divided into two categories: passive suppression of road icing technology and active suppression of road icing technology. [0004] One is the passive suppression of road icing technology. According to the specific measures adopted, the passive suppression of road icing technology is divided into manual removal method, mechanical remov...

AI Technical Summary

Problems solved by technology

After the preliminary evaluation after the disaster, it is believed that the ice and snow disaster caused huge economic losses to road transportation, and the snowmelt agent seriously polluted the surrounding environment of the route. Chemical snow removal is likely to cause structural corrosion and reduce the service life of the structure. High repair costs, frequent traffic accidents, imperfect traffic emergency system, etc.
