Uso de Grano de Caucho Reciclado para mejorar la resistencia y durabilidad en pavimentos: una revisión literaria

Abstract

For several years now, globally, large quantities of tire rubber have been discarded, which exacerbates the problem of environmental pollution. A good alternative to mitigate this problem and at the same time take advantage of it in an efficient way is to obtain granulated rubber from recycled rubber to use it in pavements since it improves its resistance and durability. The objective of this document was to carry out a systematic review of the literature on the main processes to produce asphalt mixtures and the way in which the use of recycled rubber grain (CBR) affects the design and improvement of the physical and mechanical properties in the asphalt. 50 articles indexed in the Scopus database between 2015 and 2021 on recycled rubber, incorporation of granulated rubber in asphalt mixtures and the physical and mechanical properties of granulated rubber mixed with granular soils in asphalt were reviewed. After investigating in different articles, it was determined that the most important processes to include CR in asphalt mixtures are the dry, wet and semi-humid process. It is concluded that the use of CBR in its mixture improves the mechanical properties of asphalt, such as the increase in the modulus of rigidity, the increase in resistance to humidity, the lengthening of its useful life, and even has applications in the damping of vibrations in construction sites. civil construction.
