Diseño experimental de mezcla asfáltica para rehabilitación de pavimentos en vías urbanas

Abstract

This research is based on the importance of finding effective and sustainable solutions to counteract the deterioration of road infrastructure in urban environments. The aim of the study is to evaluate pavement rehabilitation processes on urban roads and to select effective restoration methods to prolong their service life. It highlights the need to improve the structure of roads to achieve optimal conditions and improve the quality of the city. The conclusions show that rehabilitation processes are effective and efficient in prolonging the service life of urban pavements. Among the problems analysed are the premature deterioration and low efficiency of pavement rehabilitation processes on urban roads, which can make driving more difficult and increase the risk of traffic accidents. The importance of a proper visual assessment to identify the specific needs of roads and to choose the appropriate rehabilitation treatment is highlighted. The study focuses on the city of Machala (Ecuador) and aims to provide solutions based on experience and science to ensure the safety and comfort of urban road users. As for the asphalt emulsion, it is mentioned in one of the results that it is used in the development of experimental mixes to evaluate aspects such as workability, resistance to moisture damage, stability and flow behaviour in a mixture of soil and emulsion.
