Análisis de asfaltos reciclados vs asfaltos conformados con lana de acero utilizando material asfáltico reciclado de la vía Guadalupe-Patate

Abstract

For the development of this research, the materials such as coarse and fine aggregate were obtained from the Las Viñas mine belonging to the company JEAL Constructions located in the city of Ambato. Laboratory tests were conducted to analyze their mechanical characteristics and determine that they comply with the standards. of respective quality for each of them. Likewise, the recycled asphalt material belonging to the Guadalupe – Patate road in the Pelileo canton was collected and its quality was determined, and it was decided to collect steel wool as a reinforcement material. Once the characteristics of the materials were determined, the specimens were prepared using the Marshall Method in compliance with the standards AASHTO T 245, ASTM D 1559 and AASHTO T 225, three briquettes of traditional asphalt for each percentage, three briquettes with additions of recycled asphalt in percentages of 20, 40 and 60 percent and three briquettes with the addition of steel wool in percentages of 0.5, 1 and 1.5 percent, for each asphalt cement content, which gives a total of 105 asphalt briquettes produced during the development of all research. At the end of the respective tests, a comparative analysis of the mechanical properties was conducted between traditional asphalt mixtures, with percentages of recycled asphalt and with the addition of steel wool, such as stability, flow, and percentage of voids, using tables and graphs.
