This paper describes how air traffic has increased tremendously over the last thirty years. As a result, many airports have experienced a continuous cycle of upgrade and expansion. Pavement evaluation methods have evolved and become an integral part of the design and rehabilitation process. Some of the unique issues associated with airport evaluation include the complex loading conditions and multi-layer pavement systems. Aircraft gross loads are continuing to increase and individual wheel loads are approaching the entire weight of a truck for which a highway pavement might be designed. In addition to the load magnitude, there are the issues associated with complex gear geometry, high tire pressures, and how to account for the effects of mixed traffic. Because of increased traffic volumes and cost to an airport for facility closures, non-destructive testing has become the preferred method for assessing the condition of existing pavements. A variety of assessment tools is now available, each having both advantages and limitations. The International Civil Aviation Organization's aircraft classification number-pavement classification number (ACN-PCN) procedure has been widely accepted. However, some interesting issues have been raised with respect to the ACN (specifying the effect of new heavy aircraft) and interpreting the PCN (load bearing capacity of the pavement). In many ways, the requirement for determining structural capacity and predicting performance under increased traffic has driven the development of new design procedures and testing equipment. This paper discusses the evolution of airport pavement evaluation methods and describes the current state-of-the-practice.
