The poor performance of keyed longitudinal construction joints in rigid airfield pavements under simulated C-5A traffic operations is presented. The data presented were collected from a full scale test track pavement supported on a low strength subgrade. No deficiencies in materials or construction were found which would have adversely affected the performance of the keyed joint. The failures observed in the keyed joint demonstrate that a balanced design will result using the Corps of Engineers keyed joint dimensions.
