The aim in this paper is first and foremost to present an experimental method for measuring the dynamic characteristics of granular rubber. Dynamic measurements on recycled granular rubbers are performed here using dynamic mechanical thermal analysis. The Young’s modulus and loss factor of these materials are estimated by using the frequency—temperature equivalence introduced by Williams—Landel—Ferry. It allows us to describe the dynamic properties over a wide range of frequencies. An increase in the wave speed and a decrease in the loss factor were observed with an increase in the frequency for ground tire rubber (GTR) and compound particles obtained by extrusion of GTR—ethylene vinyl acetate blend. However, for recycled polyurethane particles, the loss factor increases with increasing frequency. Then, we investigate the damping efficiency of granular rubbers introduced into a metallic tube, which was subjected to vibrating bending loads. A numerical model is presented to predict the frequency response for the displacement—force function of the tube—particles system. Model prediction is hence validated through a comparison with experimental results. Second, this paper also aims at calculating the optimum weight of granular material with maximum allowable damping effects on tube subjected to bending vibrations. For this purpose, a technique is proposed from the model developed by optimizing the apparent mass of granular material and the dissipation energy of the tube—particles system. Optimization is achieved by a nondominated storing genetic algorithm (NSAG-II). From the results, this technique can be successfully used to optimize the frequency dependence of wave speed and the loss factor of granular rubber with optimized weight.

In the case of road embankments, using tyre shreds as a lightweight fill, can consume large quantities of scrap tyres with certain engineering benefits.…”

A new recycling technology (namely 'direct powder moulding') is proposed to produce large rubber parts from spent tyres without any addition of virgin materials or linking agents. Rubber pads were produced by compression moulding of rubber powder mixtures which were obtained by mechanical grinding of ground tyre rubbers. In this study, the effect of different powder mixtures on the final performances of the moulded parts was evaluated. Starting from three initial size distributions of the rubber powder, other binary and ternary blends were prepared, for a total of 15 different powder distributions. All these rubber mixtures were compression moulded to produce large pads. Differential scanning calorimetry of the rubber powders was carried out as well as tensile tests and dynamic mechanical analyses on samples extracted from the pads. It was found that the rubber powder distribution strongly affects the mechanical performances of the recycled rubber moulded products.

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.
