Özet
The use of various oils and their wastes in bitumen modification is quite common. In most of the studies in literature on bitumen modification, waste oils are used as rejuvenators and to soften hard neat bitumen or polymer modified bitumen. In this study, bitumen which has 50/70 penetration grade was modified with waste vegetable margarine at the ratios of 1, 2 and 3%. Physical properties of modified samples were investigated with the help of penetration, softening point, ductility and rotational viscometer tests. Penetration index values were calculated using the penetration and softening point test results to determine the temperature sensitivities of the samples. Moreover, stripping resistances and adhesion performances of them were investigated. Test results showed that the use of waste vegetable margarine results in an increase in the penetration and a decrease in the softening point. The temperature dependent susceptibility of the samples decreased as the additive ratio was increased. The rotational viscometer tests showed that both the mixing/compaction temperatures and ranges decreased as the additive ratio increased. In addition, it is possible to say that there will be a slight decrease in the stripping resistances of mixtures containing waste vegetable margarine modified bitumen. However, rising of waste vegetable margarine ratio in bitumen increased slightly adhesion performance. According to the results obtained, it was found that the modification with waste vegetable margarine can increase the resistance of bitumen to the conditions of cold climates by affecting the consistency.
