Problems solved by technology

This kind of road surface is rough and anti-slip, which is more suitable for deceleration roads, but it is inappropriate to apply it to urban landscape roads: ⑴The scattered gravel is easy to fall off, ⑵The surface is rough, which may cause safety to pedestrians, ⑶It is also easy to deform due to insufficient deformation Cracking; therefore, there are also problems with its durability, and it is urgent to develop my country's own color landscape advanced pavement technology

Embodiment 1

[0040] The pavement structure is the ECC colored bus lane paved on the asphalt pavement:

[0041] The pavement structure includes: an EC constrained base layer paved on the asphalt pavement 1 and a concrete surface course laid on the EC constrained base layer with epoxy resin as the cementing material, and the EC constrained base layer includes a cemented base layer made of epoxy resin The material layer and the color aggregate layer sprinkled on the bonding material layer; the thickness of the EC constraining bottom layer is 5mm, and the thickness of the concrete surface layer is 20mm.

[0042] Colored pavement design requirements: red bus lanes, design thickness 25mm, pavement must be flat, rough and free of water, pavement strength should meet the needs of the bus load operation.

[0043] The specific implementation steps are as follows:

[0044] ⑴ The elevation of the asphalt pavement should reserve the pavement thickness of the colored pavement, and the surface of the as...

Embodiment 2

[0058] The pavement structure of the present embodiment is paved on the reinforced concrete bridge deck ECC color landscape sidewalk, which includes paving on the reinforced concrete bridge deck EC constrained bottom layer and laying on the EC constrained bottom layer by epoxy resin as cementing material concrete The surface layer, the EC constrained bottom layer includes a cementitious material layer made of epoxy resin and a color aggregate layer sprinkled on the cemented material layer, the thickness of the EC constrained bottom layer is 3mm, and the thickness of the concrete surface layer is 7mm

[0059] Design requirements: The colored landscape pavement is directly paved on the sidewalk of the reinforced concrete bridge deck. The pavement thickness is 10mm.

[0060] The specific implementation steps are as follows:

[0061] ⑴Shot blasting is performed on the surface of the reinforced concrete bridge deck to make the surface cleanliness reach Sa2.0 level;

[0062] ⑵Prepa...

Abstract

The invention discloses an ECC (engineered cementitious composite) durable type colored road pavement structure and a paving method thereof. The structure comprises an EC (expansive concrete) constraint bottom layer paved on the original road surface and a concrete surface layer which is paved on the EC constraint bottom layer and adopts epoxy resin as a cementing material, wherein the EC constraint bottom layer comprises a cementing material layer made of the epoxy resin and a colorful aggregate layer scattered on the cementing material layer. Compared with the prior art, the pavement structure has high stability and durability, good track resistance and water damage resistance at high and low temperature and low probability of aggregate falling condition, and the pavement performance is greatly improved by means of the concrete surface layer; the pavement structure has certain flexibility and improves resistance to thermal expansion and cold contraction, and the road is prevented from cracking, so that the service life of the road is prolonged; and besides, natural colorful road metal or artificial colorful calcinated ceramsite is selected in order to keep bright and lasting colors of the road and achieve the environmental protection purpose.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an ECC durable colored pavement structure and a laying method thereof. Background technique [0002] Urban roads are paved with colorful landscapes, which are more and more widely accepted. It not only solves the basic functions of the road, but also is more harmonious with the surrounding environment; Visual guidance effect. Colored landscape pavements will play an important role in urban traffic roads, such as: colored bus lanes, colored landscaped bicycle lanes along the river, colored landscaped sidewalks, etc. [0003] In the past, my country's exploration of colored pavement was basically a failure. In recent years, a layer coating method of colored non-slip pavement technology has been introduced from abroad, that is, a resin-based cementing material is used to scrape and coat a layer of primer on the existing pavement. Immediately spread a thin layer of high-density colo...
