Propuesta del diseño de la capa de rodadura para las vías de la urbanización Vista Hermosa, cantón Pallatanga, provincia de Chimborazo

Abstract

This research work focuses on the design and study of the rolling layer of the flexible pavement for the Vista Hermosa urbanization, its main objective is to improve the quality and durability of internal circulation roads. Engineering methods of vehicle count and pavement design were used to evaluate current traffic conditions, to propose appropriate solutions. First, a vehicle count was carried out on different days and times of the week in order to collect precise data on the flow of vehicular traffic in the area. These data were analyzed and used to determine the expected traffic loads on the roads of the urbanization, to obtain the equivalent number of ESAL'S axes, since it is an essential parameter for the design of the road surface of the pavement. Subsequently, a pavement design study was carried out using methods and standards established by the current AASHTO 93 regulations. Factors such as expected traffic, soil typologies, local climate and the material available in the work area were considered. Based on these analyses, a pavement surface structure on a flexible layer was proposed; meeting the requirements of resistance and durability. Results were obtained that show that the surface layer and the proposed pavement design is adequate for the Vista Hermosa Urbanization. Finally, after an economic study with a 20-year projection, it was determined that it is technically and financially feasible; in order to improve the quality of life of future inhabitants by providing a reliable and durable road infrastructure.
