Technical Data Base for Stabilization of Deep Soil Layers
Abstract
The majority of the airfield pavements supporting current Air Force operations were designed and built during World War II and are presently approaching the end of their design life. The nature of the aircraft for which these early pavements were designed is substantially different than the planes currently in service and the much heavier aircraft, such as the C-5A, anticipated for use in the future. In order to accommodate the heavier repeated wheel loads of the future, many of the airfield pavements currently in service will have to be strengthened. Possible schemes for improving the load-carrying capacity and performance of existing pavements fall into two broad categories: (1) conventional overlaying operations and (2) strengthening of the soil beneath the existing pavement structure with a minimum of disturbance to the existing pavement structure. In this report, the ability of various stabilization procedures to provide strength improvement to in-place subgrades was examined. Included in the stabilization procedures examined were electrical methods (electro-osmosis and electro-chemical), cement and chemical grouting procedures, lime stabilization procedures (drilled-hole and pressure injection) and a number of new techniques.
