Evaluation of the friction coefficient of sidewalks with addition of rubber grains of tires in concrete

摘要

In this work, we recycle tires producing three different particle sizes, where the grains were mixed with concreteto ecologically sustainable production of sidewalks. Through a very experimental setup used in experimentalphysics class coefficients of static and kinetic friction between two surfaces were calculated. Observed from theresult that the introduction of grain rubber tire causes a significant increase in the magnitude of the coefficientsof static friction and kinetic.
