Distillation For Cut black Bitumen

It may be defined as the amount of the more volatile constituents in cut-back asphaltic products is measured. The properties of the residue after distillation are not necessarily characteristic of the bitumen used in the original mixture or of the residue which may be left at any particular time after application of the cut-back asphaltic product. The presence of silicone in the cut-back may affect the distillation residue by retarding the loss of volatile material after the residue has been poured into the residue container.
