This report presents an assessment of the state of the art of airport pavement analysis and design. The objective is to identify those areas in current airport pavement analysis methodology that need to be substantially improved from the perspective of airport pavement design and management needs. The report presents a rational argument for developing a unified pavement analysis and design procedure that can be used for pavements of any material type including reinforced concrete and asphalt and that are based on mathematical formulations of the actual stressstrain response processes in airport pavement materials. Material behaviors can be difficult to predict with respect to their structural response to loads and environmental conditions. Material characteristics change with time, environmental conditions and tress strain relations and history. There is no consensus definition of airport pavement failure. Design procedures prescribe a pavement thickness for protecting subgrades from excessive deformation. Fatigue cracking of pavements is a relatively common occurrence, but cracking alone, is not necessarily an indication of failure. Pavement failure May be defined with respect to the serviceability level, a concept related to the roughness of the traveling surfaces.
