Liquid curing agent for making road and its production process

Abstract

The present invention relates to highway construction technology, and is especially one kind of liquid curing agent for making road and its production process. The liquid curing agent consists of sodium hydroxide, sulfuric acid, phenol, rosin powder and soft water in certain proportion. The production process includes mixing rosin powder and phenol and heating in some container, adding solution of sodium hydroxide and heating to near 100 deg.c for 2 hr, and storing the mixture inside storing container while the mixture is still hot. During construction, the liquid curing agent is mixed with water repellent agent in the weight ratio of 1-2 to 8-9, and the mixture is then mixed with soil, sand and stone. The liquid curing agent is combined with soil to produce ion exchange reaction, and this can reduce or eliminate water film attached to soil, coagulate soil grains, reduce capillary effect and raise the water resisting and antifreezing performance of road bed.

Description

[0001] The present invention is a divisional application, and its parent case name is "a kind of road construction method", and the application number is 02128770.8, and the filing date is August 6, 2002. technical field [0002] The invention relates to the field of road construction, in particular to a liquid curing agent for road construction and a manufacturing method thereof. Background technique [0003] The present known road building method is like this (as attached figure 1 shown): firstly, the prepared roadbed is rolled to the specified density with a road roller; then, the prepared roadbed soil is mixed with lime or cement, or a mixture of the two, mixed evenly, and then water is compacted to form a base The base layer; then, mix the prepared crushed stone (generally graded crushed stone, natural ore gravel, that is, sand and gravel) with cement or lime in proportion, mix evenly, add water to the specified water content, and roll to form the upper base layer , an...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the prior art are: this road construction method needs to pave a thicker subbase and upper base, especially the upper base needs to use a large amount of sand and gravel

To build roads in places where there is a lack of sand and gravel, it must be transported from a long distance, and the cost is very high. In many places, the transportation cost even exceeds the price of sand and gravel.

In addition, in the prior art, the subbase layer is required to be laid thicker, so a large amount of cement and lime is required, and the cost is higher
