Diseño de pavimentos articulados en vías urbanas para la aplicación en gad’s con poblaciones menores a 20 000 habitantes

Abstract

Most of the country's highways are built on rigid and flexible pavement, of tand that is why this document describes a design case for an articulated pavement structure carried out by the AASHTO-93 methodology, the steps followed and results obtained are detailed to elaborate an optimized design of specific conditions for traffic in a population less than 20,000 inhabitants. The AASHTO-93 methodology used for the design of this articulated pavement is designed with a broad analysis of its constants and variables; but with a very practical formula to apply to the different characteristics of the different designs. It also analyzes the problem of cities with populations of less than 20,000 inhabitants and their close relationship with tourism, in which use is characteristic of this type of articulated pavement. The structure of a pavement is the main component within a road project, therefore its due study of the soil was carried out, depending on the appropriate regulations and a traffic capacity to obtain our design ESALs. Using a specific method for an articulated pavement design, it is presented through a structural design proposal a 12.5 cm tread layer, 15 cm BASE layer and 10 cm Subbase layer, based on the AASHTO 93 methodology.
