Question 1.
What does air rectification enhance in bitumen?
Show hintHide hint
Think about what happens physically to bitumen during the process.
Question 2.
What temperature range is used during the air blowing process?
Show hintHide hint
It is a high temperature for the air blown into the residue.
3Question 3.
What is the primary purpose of the air rectification process in bitumen?
- To make bitumen lighter
- To increase viscosity and softening point
- To reduce costs
Show hintHide hint
Think about what physical characteristics the air blowing improves.
