Abstract:

The purpose of this study was to validate the mechanistic approach for the design and evaluation of Contingency Airfield Pavements CAPs containing stabilized material layers. The mechanistic approach was validated by relating predicting first pass structural response parameters stress and strain to observed performance of field test items. Major study findings included 1 Subgrade characteristics control performance in pavements with predicted first pass crack stress ratio greater than one. 2 CAPs should be designed and evaluating using an intact slab concept. 3 Design of CAPs should be based on stress or strain ratios less than one. 4 The presence of a crushed stone base course over a stabilized subbase course in an inverted pavement has a bridging effect at transfer cracks in the stabilized subbase and inhibits the rate of crack propagation to the surface.
