Abstract

The invention belongs to the technical field of road construction and particularly relates to a road curing agent and a road curing method. The road curing agent contains two parts, namely a water agent and a powder agent, wherein the water agent contains the following components by weight percent: 45%-54% of polyvinyl acetate copolymer, 6%-7% of fatty alcohol-polyoxyethylene ether and 40%-49% ofwater; the powder agent contains the following components by weight percent: 80%-90% of desulfurated ash, 9%-18% of quick lime and 1%-2% of nano-clay. The road curing agent has the advantages of low production cost, high strength after being cured, good water tolerance and slight influence to surrounding environments, can be applied to the curing of sandy soil and macadam and is an environment-friendly road curing material.

Description

technical field [0001] The invention belongs to the technical field of road construction, and in particular relates to a road curing agent and a road curing method. Background technique [0002] With the continuous increase of construction scale, my country's road infrastructure construction has also developed rapidly, and the growth of traffic volume has also increased year by year, and the requirements for roads are also getting higher and higher. In order to ensure the quality of road engineering and reduce costs, the traditional cement-stabilized gravel base needs to consume a large amount of materials such as gravel and gravel. Such resources are becoming less and less, and the construction cost is relatively high, which will cause certain environmental damage and pollute. However, the traditional curing agent currently used has a general curing effect after curing sand and soil, and has poor water resistance, which will cause insufficient strength of the base layer an...
