Development of a Thickness Design Procedure for Stabilized Layers under Rigid Airfield Pavements
The results of an analysis of two rigid layer pavement systems are presented. The outcome of the study resulted in the development of a design procedure which can account for the materials properties of the stabilized materials layer. The study employed the use of elastic layer theory and regression analysis to predict the interior stress under aircraft loading. Equivalent interior stress is used as the design criteria such that a single layer rigid pavement on subgrade is equated to a two layer system with a cement-treated base course and a portland cement concrete surface. The comparison of the developed procedures to the existing procedures show both allowable decreases and increases in the thickness of the portland cement concrete layer. The design procedure is an iterative process and was computerized.
