Özet:

 Styrene-butadiene-styrene SBS is widely used to improve the properties of the base bitumen and hence bituminous mixtures. As SBS modification induces cost increase, natural asphalts have become an important issue. In this study, the effects of gilsonite supplied from Iraq, a type of natural asphalt NA on conventional and rheological properties of bitumen, were investigated. NA was used 20, 35, and 50 by weight of bitumen. The properties of NA modified bitumen were compared to 2, 3, and 4 SBS modified bitumen. Conventional penetration, softening point, rotational viscosity and rheological dynamic shear rheometer, bending beam rheometer binder tests were conducted on base and modified bitumen. The index values representing together the workability, high and low temperature properties were defined by dividing the rutting parameter to viscosity and rutting parameter to low tempera-ture stiffness. Overall, the test results show that 20 NA modified B160220 bitumen exhibit-ed similar performance with B1602203SBS modification produced at 16 higher cost in terms of the high and low temperature properties.
