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.

Embodiment Construction

[0029] The present application will be further elaborated below in conjunction with the examples.

[0030] The specific technical requirements and preparation methods are as follows:

[0031] 1. Raw material requirements

[0032] The composition of the raw materials of the anti-icing ultra-thin wearing layer pavement is as follows:

[0033]

[0034] Among them, 10-15mm crushed stone, 5-10mm crushed stone are used as coarse aggregate, stone chips with particle size less than 3mm are used as fine aggregate, anti-icing agent is used as filler, modified asphalt is used as cementing material, and polymer modified emulsified asphalt is used as layer For inter-bonding materials, the open-graded asphalt mixture design method is used, and the specific grading and material index requirements are as follows:

[0035] 1. Grading range

[0036] The gradation type of the anti-icing ultra-thin wear layer pavement has a large void ratio, and the surface is rough, so the pavement perform...

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...
