Implementación del proceso de conservación de la estructura de la capa de rodadura de la vía Cevallos - Mocha en el tramo km 4 + 960 hasta km 9 + 920 de la provincia de Tungurahua.

Abstract

The objective of this experimental work is to implement a process of conservation of the structure of the running layer of the Cevallos - Mocha road in the section km 4 + 960 to km 9 + 920 of the province of Tungurahua, in order to obtain data of the current state of the road. Initially a georeferenced survey was carried out with the help of a total station, where length, width, gutters, water passages and sections of the existing road were identified. To know the amount of vehicular traffic, a manual count of each type of vehicle was registered, during a period of one week eleven consecutive hours to obtain the Annual Average Daily Traffic (ADT). Subsequently a pit was made every kilometer to be able to extract altered soil samples and perform laboratory soil tests such as granulometry, Atterberg limits, compaction and California Support Index (CBR) test. Also the evaluation of the Condition Pavement Index (PCI) where we identify the amount and severity of the damages located in the road surface. Finally, the Benkelman Beam test was carried out where the pavement deflections were obtained. Additionally, tables, graphs and abacuses were made that allowed us to interpret the results obtained. The abscissas, sections and units evaluated are identified in the attached plans.
