Pyrobitumen is mostly insoluble in carbon disulfide and other organic solvents as a result of molecular cross-linking, which renders previously soluble organic matter (i.e., bitumen) insoluble. Bitumen occurs in nature in several forms: hard one – easily crumbled bitumen in rock asphalt and softer, more viscous material which is present in tar sands and asphalt ‘lakes’. Another way in which bitumen can be obtained is through petroleum processing in this manner the bitumen is essentially the residue yielded through a distillation process of petroleum. MC 30 cutback bitumen is the less viscose grade of medium curing cutback bitumen, which contains approximately 35 to 40% solvent. Since ordinary bitumen is highly viscose, we liquefy it by heating, water, and solvents.
