Problems solved by technology

However, in this invention, (except that the base layer is sprayed with 0.5‰ biological enzyme solution) the mix ratio of the road construction materials is exactly the same, which is the same as that of the different structural layers of the roadbed and the road surface under the condition that the influence of vehicle load and environmental factors attenuates with the depth. The technical requirements of road materials are different, and the design and construction principles do not match; in addition, the on-site mixing of road materials and the construction process of (roadbed) subbase in this invention are unknown, not targeted, and need to be improved and optimized

Embodiment Construction

[0067] The present invention will be further described below.

[0068] A construction method for paving roads integrated with bio-enzyme-solidified materials, including the design of the mix ratio of bio-enzyme-solidified materials and its integrated paving construction method, including the following steps:

[0069] (1) Mixing ratio design of bio-enzyme solidified materials

[0070] 1.1) Selection of raw materials

[0071] Biological enzyme: a transparent brown liquid compound enzyme product produced by Nature Plus, Inc. of the United States (distributed by Tairan Lutong Technology Co., Ltd.), which belongs to the biological enzyme soil stabilizer.

[0072] Cement and lime: Ordinary Portland cement is used, and the cement grade is not lower than No. 32.5; the quality of the lime used must meet the national grade 3 lime standard, that is, the calcium and magnesium content must be greater than 75%.

[0073] Flexible fiber: Polypropylene monofilament flexible fiber is used, an...

Abstract

A bio-enzyme curing material integrated road paving construction method comprises the following steps: (1) designing mixing ratio of bio-enzyme curing materials, namely, 1.1) selecting raw materials,and 1.2) designing the mixing ratio, and recommending mixing ratio to the following bio-enzyme curing material for a road; and (2) performing bio-enzyme curing material integrated road paving construction, namely, 2.1) designing the mixing ratio of the bio-enzyme curing material, 2.2) stirring the bio-enzyme clinker at field (a method for stirring on the road), and 2.3) conveying the bio-enzyme clinker meeting the construction mixing ratio and technical requirement to a working surface; modifying the soil quality of a roadbed; integrally paving a bottom base layer, a base layer or a surface layer; shaping; and rolling. According to the method, the suitable mixing ratio is designed and the bio-enzyme curing material is designed based on different structure layers of the roadbed and a pavement; and meanwhile, related construction process links are improved; and the current demand on constructing an environmentally-friendly and resource-saving highway in current novel urbanization processcan be met.

Description

technical field [0001] The invention belongs to the technical field of road materials and roadbed and pavement construction in road engineering, and in particular relates to a construction method for paving roads integrated with bio-enzyme solidified materials. Background technique [0002] With the in-depth development of urbanization in our country, the new construction, renovation and expansion of low-grade roads in counties and townships ushered in a construction climax. Traditional county and township roads are made of mud-bound crushed gravel or roller-compacted concrete pavement. The road materials have low strength and poor quality. Various diseases of the road itself occur frequently. Road construction consumes a lot of natural building materials such as cement, sand, and stone. If things go on like this, natural building materials will tend to be scarce and surface vegetation will be destroyed, seriously endangering the ecological environment. Therefore, it is nec...
