Problems solved by technology

The upper layer 20 is equipped with a heat-insulating layer or a heat-reflective coating. With the wear and tear of the heat-resisting layer, the middle surface layer 30 and the lower layer 40 lose their heat-insulating protection. Because the cost of the heat-insulating layer is high, many economically backward areas cannot afford it. If the thermal resistance layer is repaired and asphalt is directly used for repair, the temperature of the asphalt pavement will be too high, and the volatilization of the asphalt will be more serious.

Embodiment 1

[0027] Such as figure 2 Shown, a kind of environmental protection pavement, is similar to the asphalt pavement in the prior art, comprises from bottom to top: subbase layer 60, base layer 50, asphalt lower layer 40, asphalt middle surface layer 30, asphalt upper layer 20, described asphalt upper layer The thicknesses of layer 20, asphalt middle surface layer 30, and asphalt lower layer 40 are respectively 4, 6, 8cm (also can be commonly used in the prior art) or 4, 5, 7cm or 4, 5, 6cm, difference is: all The asphalt upper layer 20 is also covered with a concrete seal 10 with a thickness less than or equal to 3 cm.

[0028] The concrete seal 10 completely covers the asphalt upper layer 20, and the harmful gas volatilized by the asphalt upper layer 20 under the condition of higher temperature is all wrapped under the concrete seal 10 to avoid gas leakage.

[0029] The subbase layer 60, base layer 50, asphalt lower layer 40, asphalt middle surface layer 30, and asphalt upper la...

Embodiment 2

[0037] Such as image 3 As shown, the embodiment 2 is basically the same as the embodiment 1, the difference is that: a reinforcement mesh 11 is also provided between the asphalt top layer 20 and the concrete seal layer 10, preferably, the reinforcement mesh 11 adopts concrete with a spacing of 200x200mm. Accompanied by the fiber net, the firmness of the concrete sealing layer 10 is increased and the service life is prolonged. The rib net 11 can also be metal net, and the spacing can also be between 150-300mm.

[0038] In embodiment 2, the step of laying the concrete seal 10 on the asphalt upper layer 20 is similar to that of embodiment 1, the difference is: after step 2, the described reinforcement mesh 11 is paved on the cleaned asphalt upper layer 20, and then Carry out the pouring of the concrete sealing layer 10 of step 3. The concrete is connected to the asphalt upper layer 20 through the reinforcement mesh 11, further increasing the firmness between the two.

Embodiment 3

[0040] Figure 4 Shown is a schematic diagram of the environment-friendly pavement after the asphalt upper layer 20 as the thermal resistance layer is damaged. Fill in the asphalt repair layer 80 at the damaged part of the asphalt road, the upper surface of the asphalt repair layer 80 is flush with the surface of the original asphalt road, and then lay a concrete seal 10 on the repaired asphalt road to avoid more harmful gases overflow.

Abstract

The invention discloses an environment-friendly road surface and meanwhile discloses a construction method of the environment-friendly road surface. The pitch road surface comprises a bottom base layer (60), a base layer (50), a pitch lower layer (40), a pitch middle layer (30) and a pitch upper layer (20) from bottom to top. The pitch upper layer (20) is further covered with a concrete sealing layer (10) with the thickness being smaller than or equal to 3 cm and for preventing harmful gas of the pitch road surface from leaking in a bonded mode. The harmful gas volatilized by the pitch road surface is sealed below the concrete sealing layer, leaking of the harmful gas is prevented, air pollution is reduced, and body health is facilitated. Through the elasticity of the pitch road surface, the problems that in the prior art, a concrete road surface is large in hardness and poor in driving comfort are solved.

Description

technical field [0001] The invention relates to the field of roads, in particular to an environment-friendly road surface and a construction method thereof. Background technique [0002] At present, urban roads are mainly divided into two types: concrete pavement and asphalt pavement. Concrete pavement has the advantages of high strength, good stability, good durability (can be used for 20-40 years or longer), and good driving effect at night; but there is a lot of noise , poor driving comfort, and bumps at the joints of the road surface. Asphalt pavement has the advantages of soft surface, smooth surface, no joints, comfortable driving, low vibration, low noise, wear resistance, no dust, easy cleaning, short construction period, easy maintenance and repair, etc., but it is easy to age, dark pavement is easy Absorbing heat, the road surface is exposed to the air, and the inherent harmful gases in the asphalt volatilize into the atmosphere, polluting the environment and enda...
