Estudio de una mezcla asfáltica en frío con material reciclado e incorporando fibras de vidrio para actividades de mantenimiento vial en el Distrito Metropolitano de Quito

Abstract

In the city of Quito, several techniques and types of mixtures are used in road maintenance tasks. Generally, the hot mixture is used on roads with greater traffic, and on roads with less traffic, the cold mixture is the most used due to its versatility and the advantages that it presents by not being heated, thus the proposal of a modified cold mixture arises that aims to use recycled material with glass fibers, to evaluate its physical-mechanical properties and verify what conditions it meets and if it could be used for routine patching or road rehabilitation activities. For this study, the cold asphalt mixture is prepared with diluted RC-250 asphalt, milled material, natural aggregates and glass fibers in different percentages that increase progressively up to 1.25%. The characterization of its aggregates is important in the mixture; therefore, both the aggregates and the recycled material will be tested in the materials laboratories, and once the mixture is formed, it will be tested in the pavement laboratory to identify its properties and suitability.
