The effect of waste photo polymer on conventional and rheological properties of bitumen

In order for the bituminous layers on the pavement to serve the increasing traffic volume for a long time without maintenance and repair, it has become inevitable to improve the properties of the bitumen used in it. For this purpose, mostly polymer type additives are used. Polymer type additives used in bitumen and bituminous mixtures are generally originating from abroad and expensive materials. The problem to be solved in bitumen modification is whether the additives to be used in the mixtures are compatible with bitumen, while increasing the performance at the same time, and whether they are a solution to economic and environmental problems. In this study it was investigated at which content of waste FP the various performance parameters of SBS modification which is widely used and expensive, could be obtained. In the study, B100/150 grade pure bitumen was modified with 3%, 5%, 7% and 9% FP and 5% SBS by weight. Softening point, penetration, rotational viscosity, dynamic shear rheometer, bending beam rheometer, storage stability and Fourier transform infrared spectroscopy experiments were applied to binders. As a result, it was determined that FP modification and bitumen were in good harmony and a good polymer network develops, approximately 10% FP modification had similar properties with 5% SBS modification, 7% FP, 9% FP and 5% SBS modified binders were suitable for extremely heavy traffic conditions at 64 ℃, the addition of two times more FP than SBS gave better results than the SBS modification in terms of low temperature behavior and storage stability.
