The purpose of this investigation was to conduct a study of Corps of Engineers pavement overlay design to determine if it would be possible to reduce the thickness of an overlay if a rigid pavement was overlaid with full-depth asphalt. This study indicated that for material meeting Corps of Engineers guide specifications, there would not be an equivalency ratio between asphalt-bound and unbound material. However, for material not meeting Corps of Engineers specifications, it is possible to upgrade these materials by the addition of asphalt and thereby reduce the thickness requirements for the asphalt-bound material.
