A review of the literature is presented that deals with the rate of crack propagation and a reliable failure criterion for pavement design having an asphalt concrete surface and a clean, crushed stone base over a compacted subgrade. It has been shown for a variety of paving materials that fatigue characterizations in terms of fracture energy are as good or better than stress or strain fatigue characterizations. This conclusion was based on a comparison of statistical parameters representing data dispersion in regression analyses. It has also been shown that elementary principles of fracture mechanics, such as the Griffith theory, can be used to explain certain aspects of the complicated relationships between different fatigue curves.
