Penetration Bitumen Grade 10/20
Bitumen grade 10/20 is a premium brand that is dark brown or black color similar to cement-sahape 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 grade bitumen 10/20 has penetration between 10~20 desi-millimeter and softening point between 58 ~ 66 c. The penetration grade bitumen 10/20 has a thermoplastic property which is like as synthetic resin material which gets softer with heating and hardens when cooled. This grade of bitumen 10/20 has very strong viscosity compare to other grades.
Application of bitumen 10/20 grade:
Penetration bitumen grade 10/20 is used for paving, road construction and used for hot mixed asphalt because of the properties of very strong viscosity compared to other grade.Data Sheet of bitumen 10/20:
