Análisis del comportamiento mecánico de una mezcla asfáltica abierta con la adición de fibras de acero

Abstract

For the development of this research project, the materials of JEAL Construcciones located in the city of Ambato were obtained, to which laboratory tests were performed to analyze their mechanical characteristics and to comply with the respective standards for each of them. Given the characteristics of the materials constituting the asphalt mixture, the briquettes were prepared by the Marshall Method in compliance with the AASHTO T 245, ASTM D 1559 and AASHTO T 225 standards. Three traditional asphalt briquettes were prepared and tested for each percentage of asphalt cement and three asphalt with addition of steel fibers in percentages of 1%, 1.5% and 2% for each content of asphaltic cement, thus gives a total of 60 asphalt briquettes. At the conclusion of the briquettes tests, a comparative analysis of the mechanical properties between traditional open asphalt mixtures and open asphalt mixtures was carried out with the addition of steel fibers; such as stability, flow and percentage of voids, through the use of tables and graphs.
