Penetration Bitumen Grade 90/130

Bitumen grade 90/130 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. Bitumen Grade 90/130 has mechanical properties as below table. Penetration bitumen grade 90/130 has properties of 90~130 desimilimeter and softening point 43~47 Deg.C.
Bitumen 90/130 could also be a specialist fuel grade, typically exclusively created in regarding 65th of refineries around the world and with a yield of exclusively 3%~4% of the total crude slate, bituminous crudes from the likes of oil countries tend to supply rather additional, but these a further specialized refinement methodology, means that on the way facet the potential of most ancient refineires.

Application of bitumen 90/130 grade:
Penetration bitumen grade 90/130 is used for paving, road construction and used for hot mixed asphalt because of the properties of very strong viscosity compared to other grade.

Bitumen 90/130 is Elastic and Plastic:
When one takes a thread of bitumen 90/130 from a sample and stretches or elongates it, it is the power to return to a length preparing to its original length eventually.
For many bitumen 90/130 this technique might take longer than others.

The properties are mentioned as a result of the elastic character of bitumen.
When temperatures unit of measurement raised, equally as once a load is applied to bitumen 90/130, the bitumen 90/130 will flow, but will not come back to its original position once load is removed.
This condition is alleged as plastic behavior. Applying a load implies that you simply place a weight on the bitumen 90/130 therefore on subject it to fret.
This may well be throughout a groundwork science lab or at intervals the bitumen 90/130 final position at intervals the road and it's done to assess the bitumen 90/130 reaction to the load.
