Abstract: The aim of this study is to investigate the static and dynamic behaviour of multilayer materials manufactured from granular recycled rubber applied to technical flooring. The studied samples were manufactured by varying their thickness, density and granulometry, as these are the parameters that determine the performance of these rubbery materials. Two mechanical tests, static and dynamic, were carried out under controlled conditions to evaluate the mechanical behaviour of these materials by means of its modulus of elasticity and dynamic stiffness. Relating dynamic stiffness to impact sound insulation, it can be concluded that these materials are suitable for use in technical flooring, such as in fitness facilities. The selection will vary for static and dynamic behaviour, with different materials suitable for different applications. In general, the most suitable material for high stiffness applications is the one that reached values of 67.3 MPa for the static modulus and 72.96 MPa for the dynamic modulus of elasticity. The results allow for the consideration of these materials as substitutes for the most commonly used materials, such as ethylene vinyl acetate.
