New method for old road reconstruction by recycling waste materials

Abstract

The invention relates to a new method for old road reconstruction by recycling waste materials. The method comprises the processes of: first, treating an old road surface, and in the event of a cement road surface, using equipment to dig out a concrete base layer and breaking it for stand-by use, conducting an indoor test to obtain an optimal mix proportion, according to designed strength, compactness, the optimal mix proportion of test and an optimal moisture content, subjecting LF-S1 and LF-S2 soil solidifying agents, cement and water to smashing stirring till the compactness by recycling equipment, before the last three times of rolling compaction, laying two centimeters of gravel, then performing rolling compaction for three times or paving an asphalt wearing layer, using water to dilute a soil solidification solution in a ratio of 1:200 and carrying out maintenance with the obtained solution, and then paving a colored asphalt surface layer or colored gravel, with old road bed soil, the cement, the liquid soil solidifying agent (L1f-S2) and the powder soil solidifying agent (LF-S3) being in a proportion of, for per cube of compaction: 90-93%:5-8%:0.7kg:5-7%kg. Old road reconstruction by the method provided in the invention can have greatly reduced cost and reduced waste, thus the method is environment-friendly.

Description

technical field [0001] The invention relates to the field of road construction, in particular to a new method for rapid waste utilization, a soil solidifying agent used in construction and its efficacy. Background technique [0002] The roads built in the early years of our country, due to factors such as insufficient funds and underestimation of the increase in traffic flow, and severe overloading, there were widespread phenomena such as serious damage to old roads. Renovating old roads and improving road grades have become an important topic at present. In order to reduce costs and improve quality, a new technology, new material and new technology are invented to fundamentally solve the problem of old road reconstruction. [0003] The traditional method is to dig out the old road materials and transport the waste to the construction waste plant by truck, and then transport the soil, sand and gravel, and the mixture by truck. Make the base and sub-base of the two-ash soil a...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects in the existing method for the transformation of old roads, and provide a new method for the transformation of old roads from waste to treasure. The technical problem to be solved is to overcome the existing environment And the shortcomings of the technology provide a new method of old road reconstruction that can greatly reduce the cost of old road reconstruction and protect the environment, and the composition and efficacy of the liquid powder curing agent required by the method, which is very suitable for practical use
