Diseño de pavimentos rígidos en vías urbanas para la aplicación en gad´s con poblaciones menores a 20.000 habitantes

Abstract

At this time, all commercial and social activities are developed in innumerable routes or highways in Ecuador as in the whole world, the construction or restructuring of the same services is a great need because they seek to improve service and road communication in different locations. Any type of road, the pavement will continue to be the main structure, which can be classified into 3 categories; flexible, rigid and articulated. However, this work focuses on the design of rigid road pavements in a place with up to 20.000 inhabitants. The methodology applied for the design of the rigid pavement is based on the standard of the American Association of State Highway and Transportation Officials, AASHTO 93. The regulations offer a broad analysis of variables and constants that is discerned in the application of a general formula. One of the reasons for using this methodology is the perception of an economic point of view and the technical ease of designing reinforced concrete slab thickness. As a final result, by following the AASHTO Regulations and Ecuadorian technical regulations, a structural proposal of a rigid pavement with reduced concrete thickness, reinforced with steel rods and transverse joints will be presented. The structural design features a concrete slab thickness dimension of 21.74 cm and a 20 cm granular base.
