The penetration test of bitumen is primarily used to determine its:
Correct answer: B. Consistency or hardness at a specified temperature
- A. Resistance to aggregate crushing under impact
- B. Consistency or hardness at a specified temperature
- C. Adhesion between concrete and steel bars
- D. Loss of mass under abrasive wheel action
Explanation
The penetration test measures the depth reached by a standard needle under specified load, time and temperature. It indicates the consistency of bitumen, while abrasion and impact tests apply mainly to aggregates.

About Transportation Engineering
Transportation engineering covers highway planning and alignment, traffic studies, road geometric design, pavement materials and flexible or rigid pavement construction. It also includes railway, airport and traffic engineering concepts such as sight distance, superelevation, signals, capacity and level of service, distinguishing pavement failure from poor geometric design.
