Evaluación geotécnica de pavimento flexible en vías urbanas de Machala, un enfoque para ciudades costeras, aplicando la metodología empírico mecanista

Abstract

The research focuses on the inadequate road service present in the urban roads of Machala, Ecuador, taking into account the road capacity and the wearing course, which have been affected by deterioration and increased operational costs. Therefore, this study aims to evaluate the structure of flexible pavements in coastal cities, analysing road capacity and the wearing course to improve mobility in Machala. An empirical-mechanistic methodology was applied, using CBR tests, modified Proctor, granulometry, and fatigue tests. Through statistical analysis (ANOVA), the following results were obtained: Sample 1 showed values of 2.20%, 2.10%, and 2.00%, while Sample 2 recorded 4.30%, 4.20%, and 4.10%, with averages of 2.10% and 4.20%, respectively, indicating greater strength in the second sample. Significant differences were observed in the bearing capacity of the subgrade, leading to the proposal of a 7 cm wearing course, a 20 cm granular base, and a 25 cm thickness for high-traffic roads. The study highlights the importance of having a road management system that ensures the maintenance and rehabilitation of roads to provide efficient and safe transport routes.
