Análisis comparativo de las metodologías para el diseño de pavimentos rígidos que optimicen el desempeño de vías urbanas

Abstract

The high costs of construction and maintenance of roads, accompanied by the annual increase in the number of vehicles, generates the need to have road corridors that allow easy transit for users, and imposes the challenge of creating new alternatives for the construction of pavements. From this need, new design methodologies have been developed, such as TCP Pavements- concrete slabs with optimized geometry, which breaks with traditional design paradigms. In this methodology, the size of the slabs is designed so that only one set of vehicle wheels rests on it, drastically reducing the stresses supported by the slab and allowing its thickness to be reduced, making it possible to build friendly rigid pavement roads. environmentally friendly and low cost, without sacrificing comfort, durability and road functionality. In this investigation, the design of Luis Ángel León Román Avenue in the city of Machala was studied as a particular case, where pavement structure analyzes were carried out using the AASHTO 1993 methodology (American Association of State Highway and Transportation Officials), methodology empirical study of pavement design, with which the MOP-001-F-2002 "General Specifications for the Construction of Roads and Bridges" was developed, current regulations in Ecuador, for the construction and design of highways, and this design will be compared using the TCP Pavements methodology, in order to compare them based on their functionality and optimization of resources to determine which design methodology represents a better cost/quality benefit to be used in different urban roads in the country.
