MAMANI GONZALO, Griselda et al. Stabilization of the subgrade with quinoa ash and lime on the Lago Sagrado Highway, Puno, Peru. Infraestructura Vial [online]. 2023, vol.25, n.44, pp.85-92. ISSN 2215-3705.

The highways that connect the populated centers of the city of Puno in Peru, lack of paved roads, most of the connecting roads are carriageable trails. In addition, these roads make it difficult for vehicles to move continuously and safely due to the presence of holes and deformation caused by rain. Then, the purpose of this research was to determine the effect of the combination of quinoa ash and lime as soil stabilizers. The samples and data were processed using applied methodology, pure experimental design, and quantitative approach. The results showed an improvement in the characteristics of cohesive soils after adding quinoa ash and lime. With the addition of 9 % quinoa ash and 5 % lime, a small variation of the liquid limit, plastic limit and plasticity index was obtained in comparison with the foundation soil. Similarly, in terms of dry density and moisture content, a decrease in the optimum moisture content of 9 % was obtained, and an increase in the dry density of 1,902 g/cm3. The CBR increased reaching values of 32,0 % at 100 % dry density and at 95 % dry density showed a value of 25,6 %. It is concluded that there is an improvement in the mechanical properties of the soil with the addition of quinoa ash and lime.
