Bitumen grade 50/70 is a premium brand that is dark brown or black color similar to cement-shape semi-solid or viscous liquid form produced by the non-destructive refining of crude oil during petroleum refining.

The exact chemical composition of bitumen is dependent on the chemical complexity of the original crude oil and the manufacturing process. Penetration bitumen grade 50/70 has properties of 50~70 desimilimeter and softening point 46~58 Deg°C.
