The construction of road works in the world has always been a challenge for engineering, especially in areas where the conditions and types of soil are not adequate for the execution of this type of projects. The main objective of the present study is to establish the influence that has the rice husk ash (RHA) to stabilize the subgrade layer of a no pavemented road, composed of a low resistance clayey soil located in the Callampampa hamlet, in Chota - Cajamarca. During the initial tests, it was determined that the clay is a CL, according to the SUCS classification, and also a CBR (California Bearing Ratio – ASTM D 1883) value of 4.30% was obtained for this clayey soil. RHA is a waste and pollutant material for the environment, is considered an economical and, at the same time, ecological alternative for stabilizing a soil. Thus, several tests were carried out where it determined the value of CBR increased from 4.30% to 20.70%, by adding a 20% RHA dosage, achieving its optimum value to be considered a very good subgrade according to the “Design Manual for unpaved roads with low traffic volume” of the Ministry of Transport and Communications. In this way, it can be concluded that the addition of RHA considerably increases the geotechnical properties of the soil, turning a poor soil into a very good one.
