Penetration Bitumen Grade 40/50

Bitumen grade 40/50 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 40/50 has properties of 40~50 desimilimeter and softening point 52~60 Deg.C.

Application of bitumen 40/50 grade:

Penetration bitumen grade 40/50 is used for paving, road construction and used for hot mixed asphalt because of the properties of very strong viscosity compared to other grade.
