Özet

The aim of the study is to investigate the effects of activated carbon (CA) on the rheology of bitumen, and to optimize the activated carbon size and ratio in bitumen modification. The use of CA produced from waste hazelnut shells in bitumen modification is evaluated. Different sizes and ratios of CA are used. Test results show that a CA particle size smaller than 0.063 mm is the most effective, and that the CA modification increases the bitumen consistency and high temperature performance, while reducing the temperature susceptibility and weight change.
