Bitumen grade 70/100 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 70/100 has properties of 70~100 desimilimeter and softening point 43~51 Deg°C.

- Poly Bag
- For paving
- Road construction
- Used for hot mixed asphalt because of the properties of very strong viscosity compared to other grade
