Problems solved by technology

[0007] When laying the cement concrete layer, the traditional ordinary cement concrete is a brittle material with small deformation capacity, easy to crack, sensitive to the support condition, and prone to disease on the road surface. In addition, the large shrinkage of the concrete during construction will also lead to concrete cracking
[0008] When overlaying asphalt concrete, due t

Embodiment Construction

[0028] An example below:

[0029] Its structure is: cement concrete bottom layer 3, adhesive layer 2, porous cement concrete overlay 1, cement concrete bottom layer 3 is laid with adhesive layer 2, and the upper surface of adhesive layer 2 is paved with porous cement concrete overlay 1.

[0030] The specific implementation mode of the present invention is: at first cleaning the cement concrete bottom 3 that formed earlier, then polymer material elastic acrylic emulsion, cement, according to the weight mixing ratio——polymer material elastic acrylic emulsion (containing auxiliary agent defoamer 0.05, Water 0.5): cement=1: 3, adopt artificial stirring evenly, then artificially brush the polymer cement slurry that forms on the asphalt concrete road surface, will form adhesive layer 2 after the polymer cement slurry is solidified, in the acrylic cement slurry When it is completely solidified, use a cement concrete mixer to prepare porous cement concrete with a certain dry consisten...

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 overlay with a bonding layer on the cement concrete and a construction method thereof. 2. Background technology [0002] 1. Cement concrete pavement overlay and overlay method [0003] Cement concrete pavement is one of the main pavement forms commonly used in highways and urban roads. When the cement concrete pavement needs to be overlaid or overlaid, the following two methods are currently used: [0004] One, paving cement concrete on the cement concrete pavement. In this case, the overlay material is still cement concrete, and the overlay cement concrete belongs to a dense structure, which is formed by pouring and vibrating processes. According to the stress state of the overlay, it can be divided into combined overlay and separated overlay. The combined overlay means that the overlay and the cement...
