Effect of pyrolysis char produced from co-pyrolysis of waste sycamore leaves and plastic cups on bitumen viscosity and high temperature performance grade

Abstract

In this study, the effects of pyrolysis char produced from co-pyrolysis of waste sycamore leaves and plastic cups on bitumen viscosity and high temperature performance grade were investigated. For this purpose, 50/70 penetration bitumen was modified with pyrolysis char produced by weight of 6% and 12% ratios in bitumen. Softening point test, penetration test, dynamic shear rheometer (DSR) test and rotational viscosity (RV) test were applied on pure bitumen and modified bitumens, also temperature susceptibility of bituminous binders were evaluated by determining the PI values. As a result, it was detected that pyrolysis char used as additive by weight of 6% and 12% ratios in bitumen increased the viscosity of pure bitumen approximately 33% and 83% ratios at 135?, increased the rutting resistance of pure bitumen 46% and 24% ratios at 70? respectively and increased the high temperature PG of pure bitumen. © 2021 Gazi Universitesi Muhendislik-Mimarlik.
