Penetration Bitumen Grade 70/100

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.

Application of bitumen 70/100 grade:

Penetration bitumen grade 70/100 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 70/100 is Elastic and Plastic:

When one takes a thread of bitumen 70/100 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 70/100 this technique might take longer than others.
When temperatures unit of measurement raised, equally as once a load is applied to bitumen 70/100, the bitumen 70/100 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 70/100 therefore on subject it to fret.
This may well be throughout a groundwork science lab or at intervals the bitumen 70/100 final position at intervals the road and it's done to assess the bitumen 70/100 reaction to the load.
