Embodiment example 2
[0024] Implementation case 2, select a village-level pavement in the south-central region with a total area of about 2,000 square meters, and choose summer construction. Use this kind of soil curing agent at a rate of 1.2 / 10,000, a total of 100kg, 4% cement is evenly mixed and then compacted, and the surface is sprinkled with 2kg of stone powder per square, directly as the surface layer, completed in August 2008, and cored in October 2010 to resist compression The maximum strength is 8.5Mpa. It has been used so far without any cracks on the surface. The traffic is normal. It does not slip when it rains, and it does not ash when it is sunny.

Abstract
The invention discloses a soil curing agent directly processing soil into the surface layer of a road and provides an environment-friendly soil curing agent, which has very obvious soil curing performance and wide practicability and is simple in construction. Particularly, when field soil is directly processed into the surface layer of a road by the soil curing agent and the composite cured soil directly substitutes a cement surface layer and an asphalt surface layer, only a small amount of curing agent and 2 to 5 percent of cement are mixed and then the mixture is used for stabilizing the surface layer, wherein the compression strength in 7 days can be up to 5 to 10MPa. The soil curing agent meets the requirement of directly substituting for a base layer, a water stability layer and the surface layer; the construction cost is saved by 30 to 50 percent; the soil curing agent has a low price and high fireproof performance, shock resistance and durability, is simple in construction, overcomes the performance defects of the traditional soil curing agent; and serving as the surface layer, the soil curing agent better accords with the social requirements of environment friendliness, ecology and energy conservation.
Description
technical field [0001] The invention is a part of highway and municipal construction projects, and belongs to the technical field of fine chemicals. Background technique [0002] Soil stabilizer technology has been used in foreign countries for more than 30 years, and has been widely used in national highways, airports, seawalls, ports, wharfs, water conservancy anti-seepage and other engineering projects. This technology mainly uses in-situ soil to strengthen the roadbed, so that a more solid, stable and durable overall plate structure is formed, and the problems of water damage, irregular settlement, reflective cracks and other common problems in the old technology roads can be solved. , thus greatly improving the load capacity of the subgrade, making the road surface layer thinner and the gravel base layer cancelled. As a result, the direct investment in road foundation is reduced, and the cost of road maintenance is reduced. [0003] The application technology of soil ...
