In this research, the stabilization of sandy soils of the access roads to agricultural areas incorporated by the Chavimochic project was studied through the addition of clarification sediments of irrigation waters that optimize and increase their granulometric gradient and cohesion respectively, as well as the addition of ash rice husk (CCA) and limestone residue from scallop shells (RCCA) to improve its support capacity. The objective was to determine the influence of the addition of alkaline activated rice husk ash on the ecological stabilization of the soil sediment mixture for use on unpaved roads in the province of Virú. Soil and sediment were collected in the Chao district, department of La Libertad. The physical properties, chemical composition and phase analysis of the soil, sediment, CCA and RCCA were determined according to ASTM standards. The results of the Attemberg limits s...
