Relación costo beneficio en el mantenimiento de carreteras de segundo orden estabilizando la subrasante con cal o cemento.

Second-order roads lead to first-order roads, which is why they are vital for populated areas that are not close to main roads. Therefore, it is important to look for economic alternatives that provide benefits to users. One of these alternatives is the stabilization of subgrades through the addition of lime or cement in the case of the Cascada de Puelazo – Bocatoma road. Obtaining through tests that soil types such as clay and ballast are found on the study route. For the clay samples, the use of 4% lime is the optimal option, while for the ballast sample, the optimal addition percentage is 6% cement. The ten-year maintenance cost of a lime-improved in the subgrade corresponds to $0.31 per meter in the first 10 years. The ten-year maintenance cost of an improvement in the subgrade corresponds to $0.34 per meter in the first 10 years. The benefits provided by subgrade stabilization from a technical point of view were demonstrated in this research, obtaining an improved rigidity modulus of more than double the initial one, but also considering that the maintenance value applies to rural sectors such as in our case study.
