1.Description of the product
Road bitumen 35/50 is produced in the process of oxidization of a vacuum residue obtained from the distillation of crude oil by the continuous method on the BITUROX installation (license of an Austrian engineering company PÖRNER).
Road bitumen 35/50 can be used for asphalt mix production, especially for asphalt subbases and binder courses.
