How does an ESAL differ from a truck factor?
What will be an ideal response?
A truck factor is defined as the number of 18,000 lb single load
applications caused by a single passage of a vehicle. The ESAL, equivalent single
axle load, is the number of repetitions of an 18,000 lb single-axle load applied to
the pavement on two sets of dual tires.
