In the present trend, most researchers considered recycled tire materials as substitutes for aggregates in geotechnical applications. But, The strength of the aggregates is very high compared to tire material. The application of tire material is mainly used in earthquake-prone areas because tire materials can withstand more vibrations compared to aggregates. But, few researchers reported that the damping ratio increases with an increase in tire content in the aggregates and tire mixture. Is it correct? If yes, what is the reason, and what is the point of considering tire material as the substitute for traditional aggregates?
I do not know about details on aggregates and tire granulates in soil. But from working with tire granulate mats for gyms e.g. I will say that in general the damping is low in such mats and lower than for PUR foam or EVA. One can simply see it on how high the dropped weights bounce after fropping them on the mats, and secondly hopw many bounces they make before the weight comes to rest. In genreral the tire shreddings mats will behave more «bouncy» and thus have less losses.
