DESIGN AND CONSTRUCTION OF AIRPORT PAVEMENTS ON EXPANSIVE SOILS

This investigation reviewed the current engineering literature and synthesized from it a design procedure for stabilizing expansive soils beneath airport pavements. To do this, the study was divided into specific areas: Methods of identifying and classifying the types of soil that are considered expansive and cause early pavement distress; Laboratory and field test methods to determine the level of expansion and shrinkage, i.e., prediction of heave; and the design of stabilized soil layers including (a) selection of the type and amount of stabilizing agent (such as lime, cement, or asphalt), (b) test methods to determine the physical properties of stabilized soil, (c) test methods to determine the durability of stabilized soil, and (d) field construction criteria and procedures. The conclusions and recommendations are based on the current literature, without laboratory verification. Soil-volume changes caused by factors such as frost heave and salt heave were not studied. It was found that while procedures for soil stabilization have improved significantly, the test methods that were developed do not provide a marked improvement over those currently used.
