Q. How is cutback bitumen made?

Answer

In order to create cutback bitumen, conventional bitumen is thinned out with a petroleum-based solvent. Since cutback bitumen has a lower viscosity than neat asphalt, it can be employed for low-temperature tasks. When a cutback is performed, the solvent is removed, leaving behind only the Bitumen. When the petroleum solvent in a bitumen cutback evaporates, the bitumen is said to cure. Primers and tack coatings made from cutback bitumen are the norm. Road oils, or slow-curing oils, are typically the byproduct of the fractional distillation of various crude petroleums. Naphthenic, paraffinic, and aromatic oils have all been utilized traditionally.
