PURPOSE: Provided are a method for producing pressed soil concrete and a pressed soil concrete composition, which prevents scratch of surface and frost damage, and has strength and abrasion resistance, as well as shows natural appearance. CONSTITUTION: The soil concrete composition consists of 500-1000 kg/m¬3 of natural clay or loamy sand, 300-600 kg/m¬2 of admixture for absorbing water, 150-250 kg/m¬3 of cement, 500-1000 kg/m¬3 of fine aggregate, and 100-200 kg/m¬3 of water for mixing. The soil concrete composition is produced by the steps of (i) introducing 500-1000 kg/m¬3 of natural clay and loamy sand into hopper, mixing the natural clay and loamy sand with 300-600 kg/m¬3 of admixture for absorbing water having a fineness of 4,000 cm¬2/g and more to allow the admixture to partially absorb moisture of clay or loamy sand, and introducing the resulting mixture into crusher to crush the mixture into powder; (ii) mixing 150-250 kg/m¬3 of cement, 500-1000 kg/m¬3 of fine aggregate and 100-200 kg/m¬3 of water into the powder and adding 80-170 kg/m¬3 of water for mixing to the mixture to form a paste of soil concrete; and (iii) applying the paste onto road surface and pressing the paste.
