PERMEABLE SOIL PACKING METHOD USING SELECTIVE HARDENING SOIL

摘要

The present invention relates to a permeable tough soil pavement method using screened soil. The pavement method comprises: a mixing step of making a mixture by homogeneously mixing 70-90 wt% of screened soil having a particle size of 13 mm or less with 10-30 wt% of a non-sintered inorganic binder; an additive adding step of spraying 1-20 parts by weight of a dilution liquid, where ethylene and a vinyl acetate copolymer are mixed and diluted, with respect to 100 parts by weight of the mixture while mixing the mixture using a mixer, in order to be cured in a spherical aggregate; a laying and sprinkling step of laying the mixture with the additive on the laying surface, mixing 10-30 parts by weight of a diluted water, where a non-sintered inorganic binder or a vinyl acetate copolymer, and ethylene are diluted in water, with 5-30 parts by weight of water with respect to 100 parts by weight of the laid aggregate, and sprinkling the mixed diluted water to the laying surface in order to solidify the laying surface; and a tough soil packing step of performing compaction on the laying surface with a roller and then curing in order to form a pavement surface, upon completion of the laying and sprinkling step. According to the present invention, the pavement method can be environmentally friendly using soil instead of cement, in particular, can prevent destruction of the surrounding ecosystem by maintaining permeability, can prevent the alkalization of soil, and can minimize flood damage in case of rain.
