Análisis del comportamiento del asfalto reciclado mezclado con vidrio de la vía Cevallos – Mocha en el tramo km 0 + 000 al km 3 + 306 de la provincia de Tungurahua

Abstract

Currently, various techniques are used for the design of asphalt mixtures; however, in Ecuador, the implementation of materials such as crushed glass and asphalt pavement has not been fully accepted. The current project aims to analyze asphalt mixtures with partial substitution of these recycled materials, addressing both the environmental and economic aspects. Therefore, we started with a preliminary study where we collected data on the road under study and basic information on the incorporation of RAP and crushed glass, tests were carried out on the stone aggregates and recycled materials in order to evaluate their quality and determine their mechanical properties, 15 conventional briquettes were made, Through the Marshall method, an optimum percentage of asphalt was obtained, allowing to obtain an adequate asphalt mixture that served as a base to substitute the proportions of the materials in question, four design alternatives of asphalt mixtures were executed, which had different percentages of crushed glass and recycled asphalt. The first three alternatives worked with the optimum AC-20 content of the conventional asphalt mix, while for the last alternative an optimum content of 6.65 percent AC-20, 4.82 percent RAP and 4.42 percent crushed glass was determined. All the asphalt mixes were evaluated using parameters established by the MOP-001-F-2002 standard. As a result, and in compliance with the last objective of the project, the respective master formulas were established for each asphalt mix design executed.
