Análisis comparativo de costos de mantenimiento por ahuellamiento entre una mezcla asfáltica en caliente convencional y una modificada en las vías internas y patios de almacenamiento de cargas del Puerto de Manta

Abstract

Abstract: The purpose of this research is to analyze the mechanical behavior and performance of the conventional asphalt mix with AC-20 asphalt, and a modified one with SBS polymer oriented at permanent deformations, which are caused by the incidence of loads, speeds circulation and terrain conditions.Taking into account that in the country AC-20 asphalt is normally used for conventional asphalt mixtures, in this work an improvement proposal is presented through a modified asphalt mixture, which takes into account the use of a binder Asphalt modified with SBS polymer to be used in the roads and patios of the Port of Manta.The designs for both types of asphalt mixes are made taking into account the same considerations, using the same coarse and fine aggregates, assuming as the only variable the type of asphalt binder used for the mix designs.The Hamburg Wheel Tracker performance test seeks to determine the behavior that asphalt mixtures could have in relation to one of the recurring problems presented on the roads, such as rutting or permanent deformation, for which reason said test determined that the modified asphalt mixtures with SBS they have a better behavior in the service that the conventional one.
