Color pavement formed by spraying on porous cement concrete facing and construction method therefor

Abstract

The colored pavement formed by spraying on the porous cement concrete surface layer and the construction method relate to pavement projects such as pavement. The present invention first uniformly mixes crushed stone, sand, cement, water, paves to form the porous cement concrete surface layer (1), then evenly mixes the colored surface material, sprays the colored surface material on the surface of the porous cement concrete surface layer (1), A colored surface layer (2) is formed, and the colored surface layer (2) and the porous cement concrete surface layer (1) are firmly bonded together to form a colored pavement. The pavement of the present invention has strong wear resistance, good skid resistance, water permeability, noise reduction, color can be set and adjusted according to the needs of different occasions, strong identification, low pavement cost, and convenient and quick construction.

Description

[0001] 1. Field [0002] The invention relates to pavement engineering such as road engineering and a construction method thereof, in particular to a colored pavement formed by spraying on a porous cement concrete surface layer and a construction method thereof. 2. Background technology [0003] Colored pavement can play the role of traffic warning and beautify the city, and to a certain extent, it can relieve the driver's visual fatigue and better provide safe driving guarantee. [0004] (1) At present, there are the following types of colored pavement at home and abroad: [0005] 1. Colored concrete pavement: [0006] It is made by adding a layer of colored concrete (decorative concrete) on the wet cement floor, and then pressing it on the cement floor with a special mold. Colored concrete can make the cement floor present various colors, patterns and textures, simulate natural materials and textures, and outline various patterns. [0007] According to the construction te...

AI Technical Summary

Problems solved by technology

[0020] ①Colored concrete pavement: Since the colored concrete pavement is formed by treating the surface of cement concrete, its anti-skid ability is poor and it is not suitable for high-speed driving, which restricts the application of this pavement structure in high-grade highways and urban roads; another On the one hand, there are often some problems in the bonding between the surface treatment material and the concrete, which will cause the treatment layer to fall off, thereby affecting the appearance; in addition, the durability of the surface material often cannot meet the requirements, and the service life is short

[0024] In particular, it needs to be pointed out that none of the above colored pavements has water permeability function, and there is no obvious improvement in noise pollution.
