Análisis comparativo de los parámetros para la estabilidad y el flujo de una mezcla asfáltica MDC-25 con una mezcla asfáltica MDC-25 modificada con grano de caucho reciclado.

Abstract

This project focuses on the comparison of the stability and flow of an MDC-25 asphalt mix and a modified MDC-25 asphalt mix with added recycled rubber grain, offering an alternative solution to environmental, health and environmental problems. Those that affect the asphalt. In the main environmental and health problems that waste tires cause are: burning in the open air and damage to the ozone layer, these can be ideal for the reproduction of mosquitoes that cause dengue. On the other hand, the problems that affect asphalt are: permanent deformation, cracking. For the elaboration of the MDC-25 asphalt mixture, 5.5% optimal asphalt was proposed to make the different briquettes that will be tested by the Marshall method to obtain the stability and flow results of each sample. Based on the results obtained, it can be mentioned that the combination of percentage of recycled rubber grain was obtained that met all the design criteria established in the INVIAS standard, which indicates a high resistance to deformation. A budget analysis could be performed on the modified MDC-25 asphalt mix, with an economic savings of about 30% compared to the unmodified MDC-25 asphalt mix.
