Bitumen grade 85/100 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.
Penetration Bitumen Grade 85/100
The exact chemical composition of bitumen is dependent on the chemical complexity of the original crude oil and the manufacturing process.
Penetration bitumen grade 85/100 has properties of 85~100 desimilimeter and softening point 41~49 Deg.C.
Bitumen 85/100 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 85/100 grade:
Penetration bitumen grade 85/100 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 85/100 is Elastic and Plastic:
When one takes a thread of bitumen 85/100 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 85/100 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 85/100, the bitumen 85/100 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 85/100 therefore on subject it to fret.
This may well be throughout a groundwork science lab or at intervals the bitumen 85/100 final position at intervals the road and it's done to assess the bitumen 85/100 reaction to the load.
