Road construction method based on biological enzyme soil curing agent

Abstract

The invention belongs to the technical field of highway engineering construction, and particularly relates to a road construction method based on a biological enzyme soil curing agent. The road construction method comprises constructing a non-standard road or a road base layer, and constructing a road surface layer, wherein the construction of the non-standard road or the road base layer comprises: soil loosening, spraying of a biological enzyme soil curing agent solution, stirring mixing, road shaping, road surface compacting, covering and re-compacting, and the construction of the road surface layer comprises: paving a gravel grading material on the surface of the road base layer to achieve a thickness of 6-7 cm, completely mixing the gravel grading material and the base layer, uniformlyspraying 4 L of a 10% biological enzyme soil curing agent solution to each square meter of the road after the road shaping, compacting the road surface, uniformly spraying the biological enzyme soilcuring agent solution on the surface layer, and finally compacting the road. The road construction method of the present invention has characteristics of rapid construction, cost reducing, labor reducing, environmental protection and safety.

Description

technical field [0001] The invention belongs to the technical field of highway engineering construction, and in particular relates to a road construction method based on a biological enzyme soil curing agent. Background technique [0002] Road construction projects involve a wide range of fields, covering almost all walks of life in agriculture, forestry, animal husbandry, sideline fishery. In some municipal projects (landscape projects, municipal road projects, etc.), production and operation sites (mines, plantations, etc.), it is often necessary to build various types of roads, such as temporary heavy-duty roads, permanent heavy-duty roads, fast and simple passages, Simple garden roads, etc. This type of road has high requirements for construction speed, engineering cost, carrying capacity, ecological environmental protection, etc., while traditional road construction technology has many disadvantages such as long construction period, high cost, and great impact on the su...

Problems solved by technology

In some municipal projects (landscape projects, municipal road projects, etc.), production and operation sites (mines, plantations, etc.), it is often necessary to build various types of roads, such as temporary heavy-duty roads, permanent heavy-duty roads, fast and simple passages, Simple garden roads, etc. This type of road has high requirements for construction speed, engineering cost, carrying capacity, ecological environmental protection, etc., while traditional road construction technology has many disadvantages such as long construction period, high cost, and great impact on the surrounding ecological environment.

For the construction of the base of the national highway, the base of the road built by the traditional road construction technology (such as the water stability layer, the lime soil layer, the fly ash layer, the graded crushed stone layer) needs to consume a lot of manpower and material resources, and will also cause adverse effects on the ecological environment.
