| Abstract: | Researchers are looking at the possibility of incorporating ground tire rubber (GTR) in composite materials. This study evaluates the effect of increasing the initial mixing temperature from 60℃ to 100℃ of solid tire tread compound filled with various loading (10 and 20 phr) and particles sizes (40–mesh, 60–mesh size and 80–mesh) of GTR on the properties of rubber compounds and vulcanizates, including cure, viscoelastic and mechanical behavior. A two–step mixing technique was employed. The results indicate that the Mooney viscosity of compounds containing 40–mesh and 60–mesh GTR increased as the mixing temperature rose. The compound containing 80 mesh size GTR showed decreased viscosity as the mixing temperature increased. Results from mechanical testing suggest improvement on the mechanical properties of the solid tire tread rubber vulcanizates containing 40–mesh size and 60–mesh size GTR with increased mixing temperature, while those of the vulcanizates containing 80–mesh size GTR reduced with increased mixing temperature.
