Item 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(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Civil, 2023-01) Chimborazo Bungacho, Erika Vanesa; Bayas Altamirano, Myriam MarisolDue 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
