AB End-of-life tires (ELTs) pose a serious environmental problem today due to their great ability to maintain theirproperties and not degrade under extreme conditions or over time. One of the ways to reuse this material isto subject it to a recovery process to obtain new raw materials that can be used as convenient.This article focuses on the nonlinear viscoelastic properties characterization of the rubber obtained by theDanish company genan®. This company has developed a manufacturing process that, via exothermic reactions,gives a renewed rubber (in form of cylinders, called pellets later on) with improved viscoelastic properties incomparison with the starting material.These pellets, with the help of a binder to form an agglomerate, are currently used in some applications toreduce the effects of accidental impacts, like, for instance, in floors of playground areas or similar applications.However, a rigorous characterization of this material has not been done still now. With this goal, acompression impact test is carried out using different impact velocities, namely, different strain rate, whichremain constant during the test. Based on the tests’ results the material behavior is adjusted into a Bergström–Boyce viscoelastic model. The shape and dimensions of the specimens, non-modifiable because they depend onthe manufacturing process, establish strong limitations to the experimental study, which have been successfullyovercome.This work is the first step to evaluate, numerically, systems designed to absorb impact loads based on thisrecycled material. Task in which the authors of this work are involved nowadays to prove, in a near future, thatthis material can be reused in passive energy dissipation systems, contributing, at the same time, to palliateenvironment and safety road problems. For that reason, the energy scattering ability of this material is, also,experimentally evaluated.
