Resumen

For soils in general, with a California Bearing Ratio of ≥ 6 % or less, they need a stabilizer that serves to improve or replace a material in a cohesive soil. The purpose of the research is to determine the influence of rubber on the soil at the Subgrade level, in percentages of 1 %, 3 % and 5 % respectively; this research has an experimental method, the samples were obtained from 03 calicatas, with a soil of silt-clay type material and ground rubber of dimensions (0,400 mm), the required tests were carried out to obtain its physical and chemical properties; as a result to obtain the bearing capacity of the soil according to ASTM 188, it was obtained that the capacity increased in small percentages, obtaining a maximum CBR of 2,04 %, which represents a challenge for the choice of the use to give to the soil, since its use would be restricted to temporary constructions or light loads. © Autor(es); 2023.
