Road building method based on modified roller compacted concrete pavement on enzyme soil solidified base layer

Abstract

The invention relates to the technical field of road engineering construction, and particularly to a road building method which solves the problems that an existing road engineering construction road structure is relatively single, easy to damage, difficult in repairing, and high in building cost. The building method comprises the steps of mixing at least biological enzyme, broken stones, soil, an additive and water according to a certain ratio and rolling to form a biological enzyme soil solidified base layer and a subbase layer (enzyme soil solidified base layer for short), and then paving a cement mixing material of the biological enzyme, rubber powder and fibers modified for multiple times on the enzyme soil solidified base layer through a paving machine, rolling and forming to obtain a novel road pavement structure based on the enzyme soil solidified base layer and a multi-element repeated-modified roller compacted concrete pavement. By adopting the road building method of the novel road pavement structure, the difficulties such as high requirement on materials selected by building a road pavement, high cost, complicated construction, difficulty in maintenance, serious environment pollution and the like are solved, and the use performance of a road is greatly improved; the novel road pavement structure has the advantages of environment friendliness without pollution, resource saving, and the like, and is remarkable in economical benefits and social benefits.

Description

technical field [0001] The invention relates to the technical field of highway engineering construction, in particular to a road construction method based on a modified roller compacted concrete surface layer solidified by enzyme soil. Background technique [0002] With the rapid development of the economy, urban and rural residents have higher and higher requirements for road driving quality. Therefore, there are currently a large number of roads that need to be newly built and upgraded. However, through investigation, it is found that the road structure of highway construction is relatively simple. The materials are also very similar. Except for a small number of roads that use flexible graded crushed stone bases, most of them use cement-stabilized crushed stones. At the same time, the lime or fly ash dust during construction is also relatively large, which pollutes the surrounding environment including crops, and consumes a lot of energy during processing, which seriousl...
