COMPOSITION FOR PAVING SOIL AND METHOD FOR PAVING SOIL ROAD BY USING THE SAME

摘要

The present invention relates to a composition for paving soil and a method for paving a soil road by using the same and, more particularly to a composition for paving soil, which stabilizes soil by activating latent hydraulic property of slag fine powder, and reducing water content in the soil by using a volume expansion effect and an exothermic reaction of calcium oxide (CaO) contained in incineration residuals, and to a method for paving a soil road by using the same. The composition for paving soil may include, with respect to 100 parts by weight of natural sediment: 5-20 parts by weight of blast furnace slag; 3-10 parts by weight of high calcium-incineration residuals containing at least 15% of CaO and at least 5% of ferric oxide (Fe2O3); and 3-10 parts by weight of desulfurization dust containing at least 5% of Fe2O3.
