Design and Construction of Airport Pavements on Expansive Soils
Abstract
This investigation was initiated to review the current engineering literature and synthesize from it a design procedure for stabilizing expansive soils beneath airport pavements. To do this, the study was broken down into six specific areas: (1) Methods of identifying and classifying the types of soil that are considered expansive and cause early pavement distress; (2) Laboratory and/or field test methods to determine the level of expansion and shrinkage; (3) Selection of the type and amount of stabilizing agent (lime, cement, asphalt, only); (4) Test methods to determine the physical properties of stabilized soil; (5) Test methods to determine the durability of stabilized soil; and, (6) Field construction criteria and procedures. This report addresses the above objectives and provides a summary of the current literature pertaining to the subject. Conclusions and recommendations were made based on the current literature, without laboratory verification. Soil volume changes caused by other factors (e. g., frost heave, salt heave) were not studied.
