Özet
The volatile organic compounds are dispersed from asphalt fume to air during the construction of the pavement. This the volatile organic compounds negatively affect the environment and the health of workers. Activated carbon is used to improve bitumen properties and reduce effect of the volatile organic compounds. Activated carbon is obtained from biomass (hazelnut shell, coconut shell) and industrial wastes which have high carbon content. In this study, the effect of commercially activated carbon on the physical properties of 70/100 bitumen was examined. 70/100 bitumen was modified with commercially activated carbon at the ratios of 0.5, 1, 2, 3, and 4% with the help of a high-speed mixer for 1 hour at 2000 rpm and 150˚C. Conventional bitumen tests (penetration, softening point and rotational viscometer) on bitumen modified with activated carbon was performed. Penetration index was calculated to determine temperature sensitivity of all modified bitumen. According to the obtained results, it is seen that as the activated carbon added to 70/100 bitumen increased, the penetration values of all modified bitumen decreased, while the softening point and viscometer values increased. Activated carbon which is added to 70/100 bitumen increased the stiffness of the bitumen. Storage stability was performed to determine performance of all modified bitumen at the high temperature. Since activated carbon which is added to 70/100 bitumen has little effect on the physical properties of modified bitumen, it is thought that the activated carbon ratios in bitumen modification should be increased.
