Rediseño geométrico y del pavimento de los tramos “Y” de Guarag-La Playa, La Playa-Capilla Pungo, estadio La Playa, con una longitud de 4.65 km, perteneciente al cantón Pujilí de la provincia de Cotopaxi

Abstract

Due to the viability conditions in the sector, the need arises to carry out a geometric and pavement redesign to improve communication and the standard of living of the inhabitants. The topographic survey was carried out by means of an RTK equipment and a Drone through the mountainous terrain, having 3 sections of road called "Y" de Guarag-La Playa with a length of 3+115.44 km, La Playa-Capilla Pungo 1+103.45 km and Estadio La Playa with 0+341.39 km. Through soil studies and according to the classification of the SUCS standard, the type of soil that predominates is MS (silty sands) and according to the AASHTO standard, it is A-4 (silty soils). When designing a low-volume paved road, there is a design period of 20 years, with a TPDA of 569 vehicles in both directions, classifying it as a Class III Collector. The MTOP 2003 specifications were used for the geometric design and drainage works. For the design of pavements, the AASHTO 93 method was increased, obtaining thicknesses of 5 cm for asphalt layer, granular base of 15 cm and granular subbase of 25 cm. The analysis of unit prices was carried out, thus having a referential budget
