A road aggregate with a high flakiness index contains a relatively large proportion of particles that are:
Correct answer: C. Thin compared with their length and width
- A. Heavy compared with their specific gravity
- B. Rounded compared with their surface area
- C. Thin compared with their length and width
- D. Soft compared with their colour and texture
Explanation
Flaky particles have a small thickness compared with their other dimensions. Excessive flaky material can reduce interlocking and make compaction and pavement performance less satisfactory.

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.
