Abstract

The effect of addition of 20 phr ground tire rubber (GTR) of 40, 60, 80 and 100 mesh sizes in hybrid carbon black/silica (CB/SiO2) reinforced solid tire tread compound on the rebound resilience and heat build-up was investigated. The hybrid filler reinforcement was in the ratio of 50/10. Two-step mixing utilizing an internal mixer and two-roll mill was employed for the mixing, while vulcanization was carried out at 150. Results show that additional GTR lowered the rebound resilience and increased the heat build-up of the vulcanizates with the 100 mesh size GTR impacting the most adverse effect on the vulcanizates. The use of hybrid CB/SiO2 reinforcement helped in the recovery of some of the lost rebound due to the addition of GTR in the matrix. The use of hybrid CB/SiO2 reinforcement contributed to only a slight reduction in the heat build-up of solid tire tread compound containing 20 phr of GTR.
