Diseño de rehabilitación vial con emulsión asfáltica en acceso a El Mate 1.7km, cantón Daule, Guayas

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The project focuses on rehabilitating the access road to the El Mate community, in Daule canton, through sustainable techniques that improve mobility and support the agricultural activity of the population. Its main objective is to design a structural solution that extends the service life of the road, considering that the use of asphalt emulsion is more advantageous than conventional methods due to its technical, economic, and environmental benefits. The proposal is justified by the need to ensure rural connectivity as a key factor to strengthen agricultural production and improve the quality of life of the inhabitants. The project included field surveys, laboratory tests, and the application of the AASHTO 93 method for pavement design. Reclaimed Asphalt Pavement (RAP), asphalt emulsion, and laboratory equipment were used to evaluate the resistance and durability of the mixtures. The results defined layer thicknesses of 41 cm for the subgrade improvement, 25 cm for the RAP layer, and 5.1 cm for the asphalt surface, along with an optimal emulsion content of 4.25 %, asphalt content of 2.55 %, and a Marshall stability of 3431 lbs. In conclusion, asphalt emulsion rehabilitation is considered the most suitable option for flexible pavements, as it combines structural performance, efficiency, and social benefits.
