Rehabilitación vial mediante estabilización y pavimentación asfáltica de calles urbanas de la ciudad de Naranjal

Abstract

In the canton of Naranjal, structural deficiencies are identified in several urban roads associated with low subgrade bearing capacity, traffic effects, and the absence of an adequate pavement structure. The aim of this project is to formulate a technical improvement proposal through base stabilization and the placement of an asphalt layer, oriented toward optimizing mobility, safety, and service conditions, if stabilization techniques increase soil bearing capacity and extend infrastructure service life. The study included traffic counts, exploratory trenches, laboratory tests such as gradation analysis, Atterberg limits, compaction, and CBR, as well as structural design based on the AASHTO 1993 methodology and current national standards. The results showed a significant improvement in the mechanical properties of the treated material and a pavement structure suitable for the projected traffic demand. The proposal achieved favorable indicators related to structural performance, maintenance cost reduction, improvement in urban mobility, and mitigation of environmental impacts, contributing to the strengthening of roadway infrastructure quality in the study area. Keywords: bearing capacity, soil stabilization, structural design, traffic flow, sustainability.
