Aprovechamiento del caucho de neumáticos fuera de uso en la elaboración de revestimiento para superficies desarrollado en la Ciudad de Cuenca, Provincia del Azuay

Abstract

The utilization of rubber from end-of-life tires (ELTs) in coating production introduces an alternative that reduces the quantity of these wastes since the biggest problem of its generation is the amount disposed of in landfills or its potential source of contamination to water, air, and soil. In the conducted study, coatings were prepared using scrap rubber as a base and shredded rubber from ELTs at six different percentages, to which several hardness, compression, abrasion, and absorption tests were conducted to determine the characteristics and behavior of these materials to evaluate their potential use in recreational and playground areas. The results obtained showed favorable characteristics. The hardness of these coatings would not cause significant discomfort to individuals due to impacts caused by falls, and they would also recover from the constant pressures that these coatings may suffer due to the application of static loads. The combination of scrap rubber and shredded rubber, ranging from 60 and 75% is highly resistant and can be used in various areas such as parks, walkways, parking lots, and spaces with high pedestrian traffic. On the other hand, those containing between 15 to 45% shredded rubber are suitable for residential yards; additionally, they have a low susceptibility to moisture infiltration (highly waterproof), resistance to environmental temperature changes, durability, and require minimal maintenance.
