Problems solved by technology

[0002] The northern part of my country belongs to the low-temperature alpine region, and the temperature difference between seasons is large. In this environment, the ordinary cement pavement will cause dislocation and bulge of the pavement expansion joints due to long-term thermal expansion and contraction. If the asphalt pavement is used, cracks will appear in winter. Phenomenon, softening and overturning will occur in summer, and the problem of road surface will greatly increase the cost of urban maintenance, and also seriously affect traffic and city appearance

Embodiment Construction

[0007] The invention is a slurry used for building low-temperature roads, which is formed by mixing water, fly ash, lime, gravel, cement and loess, wherein the mass ratio of fly ash, lime, gravel, cement and loess is 4 : 1.6: 0.3: 14: 7.7. The slurry also includes sodium hydroxide, sodium silicate or sodium carbonate.

[0008] The invention provides a slurry used for building low-temperature roads. The proportion of materials is reasonable, which not only improves the quality of the road surface, prolongs the service life of the road surface, but also has good low-temperature cracking resistance, and the use of fly ash makes waste Fully utilized, it is both environmentally friendly and affordable, and brings great convenience to the maintenance of the city.

Abstract

The invention relates to a slurry for building low-temperature roads. The invention is characterized in that the slurry is mixed from water, fly ash, lime, macadam, cement and loess, wherein the mass ratio of fly ash, lime, macadam, cement and loess is 4:1.6:0.3:14:7.7. The slurry has the advantages of reasonable proportioning and favorable low-temperature cracking resistance, enhances the road quality and prolongs the service life of the road. By using the fly ash, the slurry sufficiently utilizes the waste, and thus, is environment-friendly and economical, thereby bringing in great convenience for urban maintenance.

Description

technical field [0001] The invention relates to a slurry used for building low-temperature roads. Background technique [0002] The northern part of my country belongs to the low-temperature alpine region, and the temperature difference between seasons is large. In this environment, the ordinary cement pavement will cause dislocation and bulge of the pavement expansion joints due to long-term thermal expansion and contraction. If the asphalt pavement is used, cracks will appear in winter. Phenomenon, there will be softening and overturning phenomenon in summer, the problem of road surface has greatly increased the cost of urban maintenance, and also seriously affected traffic and city appearance. Contents of the invention [0003] The purpose of the invention is to overcome the defects in the prior art and provide a slurry used for building low-temperature roads. [0004] The technical solution for realizing the purpose of the present invention is: a slurry used for buildi...
