Utilization of Waste Ethylene-Propylene-Diene-Monomer (EPDM) Rubber Modified Binder in Asphalt Concrete Mixtures
The ethylene-propylene-diene-monomer (EPDM) rubber waste from discarded non-tire automotive rubber parts is explored as an asphalt binder modifier in this study. Rutting characterization of the binders was performed through Superpave and Shenoy rutting parameters and zero shear viscosity (ZSV). For fatigue evaluation, a dynamic shear rheometer-based elastic recovery test was performed while the cracking resistance of the binders was evaluated through the Glover-Rowe parameter. Further, Marshall stability, tensile strength ratio, and resilient modulus tests were used to characterize the performance of asphalt mixes. Results of binder testing showed that the rutting, fatigue, and cracking performance of EPDM modified binders were better than the control binder. Mix performance results indicated that the EPDM modified binders enhanced the stability, moisture damage resistance, and stiffness characteristics of the mixes. Overall, findings from the study suggest that waste EPDM has a good prospect to be utilized in asphalt binder modification.
