The presented work is dedicated to the examination of effect of hardening temperature and composition on the mechanical properties of composite material made from mechanically grinded scrap tires and polyurethane type binder with different reactivity. The influence of polyurethane type binder’s reactivity on such parameters as Shore C hardness of composite material, compressive stress at 10% deformation in statistic and cyclic mode of loading and compression modulus of elasticity were determined. Special interest was dedicated to the examination of freeze/thaw resistance in corelation with composition of particular samples in order to consider potential use of created composite material. Close correlation between composition, reactivity of the polymer binder and selected properties of the composite material was demonstrated.
