Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Ambato - Tisaleo sector Santa Rosa en el tramo de la abscisa 3+200 hasta la abscisa 6+400 de la provincia de Tungurahua

Abstract

The present experimental work and was carried out with the purpose of establishing a method of conservation of the tread layer of the Ambato - Tisaleo road in the section 3 + 200 to 6 + 400 of the province of Tungurahua. A georeferenced survey was carried out every 20 meters of the road under study using a Satellite Receiver (GPS), generating a digitization of the road. To determine the vehicle traffic study, a vehicle count was carried out manually, 7 days a week from 06:00 a.m. until 6:00 p.m. thus generating future traffic of 10,917 vehicles / day. Through the Benkelman Beam test, the behavior of the pavement structure and the subgrade was known through deflections, establishing that it generates type I deflections. With the PCI test, which establishes that samples should be taken by units in intervals allowing to know the road failures with their respective severity. Four pits were made along the road, by means of which it was possible to determine the optimal moisture content and the maximum dry density through the modified Proctor, the liquid index and the plasticity index with the Limits of Attemberg and the CBR of the ground with its respective test.
