Bitumen 40-50 is which is obtained by performing aeration process on vacuum baton (raw material of bitumen production which is taken from the bottom of distillation tower in the vacuum of oil refineries) in bitumen production units so that its permeability is between 40 Up to 50. Used in road construction industries for tropical areas, insulation and also the production of liquid bitumen is one of the applications of this type of bitumen
