Abstract :In this study, the effects of oils obtained from vegetable products on the physical, mechanical and hydrophobic properties of bitumen were investigated. Within the scope of the study, six different vegetable oils were used for bitumen modification: hemp oil, flax seed oil, laurel ghee, centaury oil, castor oil, pine turpentine oil. These are 100% pure vegetable oils, obtained by using cold press method. The bitumen was modified by adding vegetable oils to bitumen with the proportions of 3%, 5% and 7%. Including the reference group, 19 sample groups were formed with six different vegetable oils by using three different mixing ratios. The physical and mechanical properties of the prepared bitumen samples were determined, according to their contact angles their sensitivity to water, surface wetting and hydrophobic properties were determined by using the IMAGEJ program. As a conclusion of the results of the studies, it has been introduced that different vegetable oils cause serious changes in the physical and mechanical properties of bitumen, and in addition, bitumen modified with vegetable oils can make a significant contribution to removal of water from the road surface which is a major problem for traffic safety.
