Diseño de la estructura del pavimento flexible de la vía Pacto - El Paraíso, perteneciente a la parroquia rural Pacto, distrito metropolitano de Quito

Abstract

In the present study, the vehicle count was carried out for the determination of the TPDA manually, this vehicle analysis was carried out for 7 consecutive days, from 6:00 a.m. to 6:00 p.m. with a total of 12 hours, counting the cars in intervals of 15 minutes, from September 20 to 26, 2021, values that were calculated for current vehicular traffic and projected twenty years. Soil studies were carried out, with the extraction of ten altered samples that later, with care not to disturb the moisture content, the required tests were carried out in the laboratory with the aim of obtaining the granulometry, the limits of Atterberg that contains the liquid limit, plastic limit and plastic index, Modified Proctor and California Support Ratio (CBR) of the subgrade, by means of the AASHTO-93 regulation it was possible to calculate and know the thickness of the optimal asphalt structure for the volume of raised traffic for a design period of two decades. The structure of the flexible pavement was designed to determine the thickness of the sub-base and base from the rural parish of Pacto to the El Paraíso community, minimizing the detrimental impacts of urbanization processes in order to establish activity areas capable of transforming their economy in a sustainable way, favoring public and private transport, focused on strengthening the parish through tourism incentives and the conservation of flora and fauna.
