[Method of constructing soil pavement with a stabilized layer of soil particles using calcium oxide-added acrylic polymer resin]

FIG. 2 is a view schematically showing a soil package having a soil-stabilized layer formed using a calcium oxide-added acrylic polymer resin according to a first embodiment of the present invention, and FIG. 3 is a cross- , Which is a structure in which a particle is coated with an acrylic polymer resin, is used as a structure in which the acrylic polymer resin and a calcium oxide component are combined with each other to form a soil- Fig.

Referring to FIG. 2, in the case of a soil pavement having a soil-stabilized layer formed using calcium oxide-added acrylic polymer resin according to the first embodiment of the present invention, an auxiliary layer (about 40 cm) 120 and a stable treatment layer 130 of calcium oxide-added acrylic polymer resin AR-CAO of 10 to 25 cm is formed on the auxiliary layer 120 to complete the soil packing.

At this time, an acrylic polymer resin, for example, an acrylic ester copolymer serving as a binder, is combined with the ground particles, as shown in FIG. 3, by a force pulling water molecules and other materials . This is because when a non-ionic surfactant or a wetting agent reduces the surface tension of water and disperses water molecules so that an acrylic ester copolymer material is applied to a hydrophobic soil, This allows the surface of the soil to penetrate deeper, increasing the infiltration rate.

At this time, depending on the negative charge of the polymer, it is adsorbed on the surface of the soil and coated, and since the molecular size is small, the soil particles in the soil are bonded to each other through the pores. The acrylic polymeric resin thus enhances the fast and complete diffusion of water by reducing the surface tension of the water and this wetting action helps the polymeric solution to further absorb into the soil and hydrates the fine particles so that they are close to each other, Thereby forming a rigid and dense calcium oxide-doped acrylic polymer resin (AR-CAO) stabilization layer 130.

Accordingly, by mixing the acrylic polymer resin added with the additive of calcium oxide (CaO) component into the ground particles by compaction with the compaction equipment, that is, by mixing the acrylic polymer resin mixed solution containing the additive of calcium oxide (CaO) Thereby forming a calcium oxide-added acrylic polymer resin (AR-CAO) stabilization treatment layer 130.

The principle that calcium oxide (CaO) is added to a liquid acrylic polymer resin strengthens the bonding of the earth particles to the charge ions of the soil particles (soil particles). This means that as the water mixed with the soil particles evaporates and the drying proceeds, the interstices between the particles are formed and they are continuously connected to each other to form a protective film, thereby preventing the individual behavior between the particles.

The method of stabilizing a state of a particle formed using a calcium oxide-added acrylic polymer resin according to an embodiment of the present invention is a method of stabilizing a state of a solid polymer in which a polymeric group of a negative charge of a soil particle is positively charged in a state where an acrylic polymer resin and a calcium oxide It is a way to combine with the soil particles.

Specifically, the method for stabilizing a treated substrate using calcium oxide-added acrylic polymer resin according to an embodiment of the present invention is characterized in that, when an acrylic polymer resin, for example, an acrylic ester copolymer, is added between the particles Is uniformly dispersed among the particles, and starts to form a protective film. The protective film thus formed adheres to the soil particles, so that the hydration reaction proceeds and the soil particles are gradually attached to each other. At this time, as the hydration reaction progresses, the internal moisture is continuously decreased, and is condensed in the capillary pores due to volume expansion due to hydration.

Through this process, the acrylic polymer resin forms a continuous continuous filling layer in the capillary pores, thereby further increasing the adhesion to the soil particles. Also, relatively large voids generated inside the cured product are also filled.

At this time, it is possible to express the effective strength within a predetermined time by compaction while keeping the inherent nature of the soil with a material of calcium oxide (CaO) inorganic material as a main component and mixing the soil, water and additives together.

Meanwhile, FIG. 4 is a graph showing the results of uniaxial compressive strength test for each polymer in a soil pavement having a soil-stabilized layer formed using the calcium oxide-added acrylic polymer resin according to the first embodiment of the present invention.

FIG. 4 shows the uniaxial compressive strength when the mixing ratio of water and the calcium oxide-added acrylic polymer resin (AR-CAO) was 5: 1. At this time, the strength according to the mixing ratio is 2 to 7 MPa and satisfies the stability treatment performance standard of 2 MPa.

Specifically, as shown in Fig. 4, the uniaxial compressive strength test showed that the uniaxial compressive strength after one day of curing was 3.65 MPa for polymer 1, 2.12 MPa for polymer 2, and 3.27 MPa for polymer 3, 2MPa. In addition, the uniaxial compressive strength after 7 days curing showed that polymer 1 showed the greatest strength at 7.64 MPa and polymer 3 showed the least strength at 5.59 MPa.

FIG. 4 shows a comparison of the uniaxial compressive strengths of the organic solidifying agents according to the curing period. In the case of polymer 2, the strength was the lowest at 1 day, but it was higher than the polymer 3 at 3 days curing. At this time, it was confirmed that the polymer 2 was the largest and the polymer 3 was the smallest

On the other hand, in the case of a soil package having a soil-stabilized layer formed using the calcium oxide-added acrylic polymer resin according to the first embodiment of the present invention shown in FIG. 2, the calcium oxide-added acrylic polymer resin (AR-CAO ) To replace the conventional asphalt and concrete surface layer. The uniaxial compressive strength is required to be 5 MPa or more. According to the embodiment of the present invention, the carbon reduction amount can be reduced by about 22.5% as compared with conventional asphalt and concrete Lt; / RTI > That is, when the mixed material of the calcium oxide-added acrylic polymer resin (AR-CAO) is used, the carbon reduction amount is reduced by 57.41 tCO 2 / ton. Table 1 below shows the carbon emission amount per 1 km as a result of analyzing the carbon emission amount of the soil-stabilized layer according to the embodiment of the present invention.

Meanwhile, FIG. 5 is a flowchart illustrating a method of constructing a soil pavement having a soil-stabilized treatment layer formed using a calcium oxide-added acrylic polymer resin according to a first embodiment of the present invention.
