In highway pavement design, the term ESAL represents the cumulative effect of traffic expressed as:
Correct answer: C. Equivalent standard axle load repetitions
- A. Effective surface aggregate loss
- B. Estimated seasonal axle loading
- C. Equivalent standard axle load repetitions
- D. Equivalent subgrade allowable length
Explanation
ESAL means equivalent standard axle load repetitions. Different axle loads are converted to an equivalent number of applications of a standard axle for pavement design.

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.
