Problems solved by technology

[0002] The thermal power plant is a production-oriented enterprise. Whether it is the unit construction period or the operation period, the demand for roads in the plant area has always been high. When the new unit is built in the existing plant area, heavy-duty vehicles frequently enter and exit the power plant during the infrastructure construction period. Concrete roads and construction temporary roads (cement) will cause greater damage, resulting in a large number of cracks on the cement pavement
[0003] However, regardless of whether the subsequent roads use cement pavement or the more conventional asphalt pavement currently on the market, the cracked road pavement caused by the infrastructure construction period needs to be chiseled and repaired, and the construction period and cost increase sharply
Even if various protection measures are adopted during the infrastructure construction period to make the cement road surface better protected, since the new and old roads must adopt the same road surface elevation, and the original factory road elevation does not conform to it, it still needs to be chiseled to the specified elevation, and the cost and Construction period remains high

Embodiment

[0029] like figure 1 As shown, the present invention provides a kind of asphalt road based on the existing roads of thermal power plants, which can be used for the existing fixed roads and temporary roads of power plants, including adhesive 3 and road body 1 and road surface layer arranged in sequence from bottom to top 2. The road body 1 is the road base body of the existing road of the thermal power plant. The road surface layer 2 includes an adhesive layer 21 and an asphalt layer 22 arranged on the road body 1 in sequence from bottom to top. The thickness of the asphalt layer 22 ranges from 0.8 to 2.5 cm, in this embodiment, is preferably set to 2 cm. The asphalt layer 22 is made of high-performance asphalt, which has good high-temperature stability, low-temperature crack resistance, fatigue crack resistance, anti-reflection crack and anti-loosening ability. It is combined with the existing road of the power plant and the temporary construction road, and some ratios are add...

Abstract

The invention relates to an asphalt road based on thermal power plant existing road and a construction method thereof. The asphalt road based on the existing road of the thermal power plant comprises a road body and a road surface layer which are sequentially arranged from bottom to top, wherein the road body is a roadbed body of the existing road of the thermal power plant, and the road surface layer comprises a bonding layer and an asphalt layer which are sequentially arranged on the road body from bottom to top; the thickness of the asphalt layer ranges from 0.8 cm to 2.5 cm. The construction method comprises the following steps of S1, an existing road surface layer being cleaned, and a roadbed body of an existing road being obtained; S2, performing crack treatment on the roadbed body of the existing road to obtain a repaired road body; S3, spraying a bonding layer on the road body; S4, asphalt with the thickness of 0.8-2.5 cm being laid on the bonding layer, and an asphalt layer being formed; and S5, forming a new surface layer through rolling forming, and arranging the new surface layer on the road body. Compared with the prior art, the method has advantages of cost reduction, construction period reduction and the like.

Description

technical field [0001] The invention relates to road reconstruction of a thermal power plant, in particular to an asphalt road based on an existing road of a thermal power plant and a construction method. Background technique [0002] The thermal power plant is a production-oriented enterprise. Whether it is the unit construction period or the operation period, the demand for roads in the plant area has always been high. When the new unit is built in the existing plant area, heavy-duty vehicles frequently enter and exit the power plant during the infrastructure construction period. Concrete roads and construction temporary roads (cement) will cause greater damage, resulting in a large number of cracks on the cement pavement. [0003] However, regardless of whether the subsequent roads use cement pavement or the more conventional asphalt pavement currently on the market, it is necessary to chisel and repair the cracked pavement pavement caused by the infrastructure constructi...
