Introduction of BITUMIN | Grades| Properties | Highway Engineering |

INTRODUCTION

Bitumin is not naturally occuring. It is been available from crude oil and the process used for making bitumin is known as Fractional Distillation Process. Bitumin is generally a byproduct of Petroleum.It is used for designing Flexible pavement.

Grades of Bitumin:

1.  Paving Grade: Used in Construction of Road & Airport
2.  Industrial Grade: Used for Water proofing

Bituminous Properties:

1. Workability: Easy in mixing, there should not be any lumps and bubbles
2. Stability
3. Durability: Material should be anti-strip(.ie bitumin material should not come out)
4. Temperature susceptibility(25-48 degree Celsius): At different temperature the binding should be proper.
5. All weather condition
6. Flexible (Rebound)
