Porous cement concrete cement pavement having bond coat on rolled cement concrete and construction method therefor

Abstract

The invention relates to a porous cement concrete road which has an adhesive layer above the concrete, wherein above a cement concrete bottom layer 3, the invention mixes polymer and stuff uniformly, to form polymer mixture, then lays uniform the mixture mechanically or hand-operated on the bottom layer 3 to form an adhesive layer 2, then uses cement concrete mixer to mix uniformly cement, broken stone, sand and water to form porous cement concrete, mechanically lays porous cement concrete, flattens and presses the concrete mechanically or hand-operated to form a porous cement concrete face layer 1 to be adhered on the adhesive layer 2. The inventive cover structure has high strength, better anti-crack property, noise-reduction property or the like.

Description

1. Technical field [0001] The invention relates to pavement engineering such as road engineering and a construction method thereof, in particular to a porous cement concrete pavement with an adhesive layer on roller compacted cement concrete and a construction method thereof. 2. Background technology [0002] 1. Roller compacted cement concrete [0003] Roller compacted cement concrete is a new type of concrete developed in the past thirty years. It has unique properties. The properties of RCC before solidification are completely different from conventional concrete. The consistency of uncured RCC is very dry, even drier than that of industrial and civil construction dry hard concrete. It is a kind of concrete with zero slump. Super dry and hard concrete, it can make bulldozers and road rollers work on it without sinking, and it is very close to the performance of conventional concrete after solidification. Through the action of vibration force, the roller compacted concre...

AI Technical Summary

Problems solved by technology

Although the sticky layer and permeable layer are commonly used, due to the large difference in elastic modulus and temperature deformation coefficient between asphalt materials and cement concrete materials, it is generally difficult to achieve good bonding, which is why "white plus black" is commonly used The root cause of the shorter tenure

[0009] In addition, due to the poor durability of asphalt materials, the service life is short and the overall cost is expensive
