Embodiment Construction

[0032] An example below:

[0033] The structure is as follows: a bottom layer of roller compacted cement concrete 3, an adhesive layer 2, a surface layer of porous cement concrete 1, a layer of adhesive layer 2 is laid on the bottom layer of roller compacted cement concrete 3, and a surface layer of porous cement concrete is laid on the upper surface of the adhesive layer 2. 1.

[0034] The specific embodiment of the present invention is as follows: firstly clean the roller compacted cement concrete bottom layer 3 formed in advance, and then mix the polymer material elastic acrylic emulsion and cement according to the weight mixing ratio - the polymer material elastic acrylic emulsion (containing auxiliary defoaming agent) 0.05, water 0.5): cement = 1:6, stir evenly by hand, and then manually paint the formed polymer cement slurry on the asphalt concrete pavement. When the slurry is not completely solidified, use a cement concrete mixer to prepare porous cement concrete with ...

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, brokenstone, 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...
