Generally, this is described by the load equivalency factor (LEF, also equivalent axle load factor), where an axle load is said to be equivalent (producing equal pavement wear) to a number of applications of a reference (standard) axle load.
(2004) used the laboratory determined fatigue equations to develop load equivalency factors for multiple axle loading.
The main conclusion from this study is that the axle load equivalency factors should be related to applied fatigue criteria.
General Axle Load Equivalency Factors, Transportation Research Record 1482: 67-78.
Results to date are presented in three separate documents in terms of primary response load equivalency factors, primary deflection responses, and primary layer horizontal strain responses.
* Develop primary response load equivalency factors, in terms of the standard 80.100 N (18kip) axle, that express pavement damage attributed to vehicles with different weights and load distributions.
