Subgrade Stabilization using Recycled Oil and Donax Peruvians on the Usgarat - Mayday Road in the province of Otuzco

Abstract

The present study was born as a solution to improve the quality of a soil with low support capacity using non-traditional stabilizers, determining the influence of the incorporation of recycled oil (AR) and Donax Peruvians (DP) in the subgrade soil on the LI - 794 Usgarat - Mayday road in the province of Otuzco, through an experimental, applicative - explanatory methodology with a quantitative approach; For this, the soil was characterized by classifying it with “CL” and “A – 6” classification, with a plasticity index (PI) of 19.83%, 75.31% capillary absorption capacity (CAP) and 5.50% CBR, while with the optimal dosage it was possible to improve the properties to 17.65% IP, 40.58% CAP and 23.77% CBR, reaching conclude that the optimal dosage that greatly improves the physical and mechanical properties of the soil was 4% AR – 6% DP, which could go from a subgrade with insufficient category to one of very good quality.
