Abstract (en)
[origin: WO2009074348A1] Straight run bitumen is widely used for producing seals in construction, especially sealing roadways. In order to be able to get the straight run bitumen where it can be purchased inexpensively, it would have to be transported over long distances. Since straight run bitumen is viscous at ambient temperature, it would have to be transported hot, which is not possible with conventional straight run bitumen. According to the invention, the straight run bitumen is provided with a small percentage of at least one hydrocarbon polymer such that the straight run bitumen solidifies at ambient temperatures and can be transported cold in the solid state.
