Lab Tests on Bitumen to Check Quality Various tests are conducted on bitumen to assess its consistency, gradation, viscosity, temperature susceptibility, and safety. There are a number of
Bitumen is defined as “A viscous liquid, or a solid, consisting essentially of hydrocarbons and their derivatives, which is soluble in trichloro-ethyelene and is substantially nonvolatile and softens
The following are the differences between bitumens and tars. The weathering properties of bitumens are superior to those of tars. Generally greater deterioration is produced in tar than
