These differences, along with some common design assumptions between the two methods, are discussed below. Pavement design alternatives should be evaluated utilizing AC 150/5320-6, Airport Pavement Design and Evaluation, based on the planned use of the pavement (e.g., critical, cargo, parking, etc.). The Westergaard idealization has been the basis for the Federal Aviation Administration’s (FAA) concrete pavement structural design procedure.
