Proceso de conservación de la estructura del pavimento asfáltico las vías Patate - Baños, Pelileo - Patate Cevallos – Mocha y Ambato - Tisaleo pertenecientes a la red intercantonal de la provincia de Tungurahua

Abstract

In Ecuador there are problems related to the poor condition of roads due to the neglect of road maintenance policies by national and regional institutions, in order to provide comfort and safety to users, in addition to promoting the economy of the various cantons that are connected through the Patate-Baños, Pelileo-Patate, Cevallos - Mocha and Ambato- Tisaleo roads of the Intercantonal network of Tungurahua, a project was carried out to generate a road maintenance process. For this purpose, a bibliographic review of technical documentation was carried out in order to obtain a vision of the current state of the pavement with the help of the visual test called Pavement Condition Index PCI, identifying the type of faults present, their degree of severity and quantities, on the other hand, by means of the data obtained from the Benkelman beam test, the type of deflection that each road presents was analyzed. As results, it was obtained that the roads are in a range from "Good" to "Excellent", being the most representative faults Crocodile Skin, Longitudinal and Transversal Cracking, Detachment of Aggregates and Block Cracking, which require periodic maintenance for the most part, through the Benkelman beam the deflection in the pavement is Type I and Type III, finally, an analysis of unit prices with their respective technical specifications was performed where a referential budget of $ 34. 601.36 dollars according to the type of failures and quantities obtained from the PCI.
