Ampliación de la vía El Deseo – Punta Brava tramo 24+000 a 28+000 perteneciente al cantón Pangua de la provincia de Cotopaxi

Abstract

In order to improve road conditions in the sector, this technical project for the expansion of the El Deseo - Punta Brava road was carried out, which began with a reconnaissance visit to the road for the subsequent topographic survey with a total station, in the that the characteristics of a mountainous relief have been identified. Through the traffic count, a projected TPDA was determined for a design period of 20 years, based on which, the road has been classified as class III, geometrically designed for horizontal, vertical and transversal design in accordance with the parameters and recommendations of the 2003 MOP regulation. For the correct design of the road, soil tests have been carried out for each kilometer in which the moisture content, granulometry, Atterberg limits, proctor test and CBR have been analyzed; used in the AASHTO 1993 method for the design of flexible pavement determined thicknesses of 20 cm for the sub-base, 15 cm for the base and 5 cm for the asphalt layer. As drainage works, standard structures have been designed for road drainage ditches and culverts and for existing waterways. Based on items for the execution of the project, a reference budget of 1471179.86 dollars was calculated without considering VAT.
