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.
Penetration Bitumen Grade 70/100
The exact chemical composition of bitumen is dependent on the chemical complexity of the original crude oil and the manufacturing process.
Penetration bitumen grade 70/100 has properties of 70~100 desimilimeter and softening point 43~51 Deg.C.
Application of bitumen 70/100 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.
