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. 본 발명은 선별토사를 이용한 투수성 경화흙포장 방법에 관한 것으로, 13mm 이하의 입도를 갖는 선별토사 70-90중량%와 비소성 무기결합제 10-30중량%를 균질하게 혼합하여 혼합물을 만드는 혼합단계; 상기 혼합물을 믹서로 믹싱하면서 상기 혼합물 100중량부에 대하여 코폴리머 비닐아세테이트와 에틸렌이 혼합 희석된 액상의 첨가물을 1-20중량부 살포하여 구형상의 골재로 양생하는 첨가물 첨가단계; 첨가물이 첨가된 혼합물을 포설면에 포설하고, 포설면이 굳을 수 있도록 포설된 골재 100중량부에 대해 비소성 무기결합제 또는 코폴리머 비닐아세테이트와 에틸렌이 물에 희석된 희석물 10-30중량부 및 물 5-30중량부를 배합하여 포설면에 뿌리는 단계; 포설면에 뿌리는 단계가 완료되면, 포설면을 롤러로 다짐 후 양생하여 포장면을 형성하는 경화흙포장단계;를 포함하는 것을 특징으로 하는 선별토사를 이용한 투수성 경화흙포장 방법을 제공한다.본 발명에 따르면, 시멘트를 사용하지 않고 흙포장이 가능하기 때문에 친환경적이며, 특히 투수성이 유지되기 때문에 주변 생태계 파괴를 막고, 토양의 알카리화를 예방하며, 우천시 수해를 최소화시키는 효과를 얻을 수 있다.
