1.Description of the product
Road bitumen 50/70 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 (licence of an Austrian engineering company PÖRNER). Bitumen 50/70 is used in road construction for asphalt mix production, especially for wearing courses and for binder courses (in low volume roads).
