Aplicación de partículas de plástico y escoria combinados en la fabricación de mezcla asfáltica como capa de rodadura

Abstract

Abstract:In order to reduce damage to the ecosystem generated by the massive exploitation in obtaining quality aggregates for the production of asphalt mixes, alternative materials have been investigated to replace this material and provide improvements in the mix, offering better results in stability and flow of the mix. For this reason, this work was developed with the objective of analyzing the physical-mechanical behavior of hot mix asphalt by replacing aggregate with steel slag and plastic combined. For this purpose, the substitute materials, local aggregates and asphalt cement were characterized. The optimum asphalt content was found for subsequent designs with aggregate substitution by combined slag (BFS) and plastic (PL) in percentages of 0% BFS - 0% PL, 5% BFS - 1% PL, 5% BFS - 3% PL and 10% BFS - 1% PL. By means of Marshall tests, the base sample was compared with respect to the substitutions, concluding that the substitution of 5% slag and 1% plastic improves the characteristics of the mix.
