THICKNESS DESIGN PROCEDURE FOR AIRFIELDS CONTAINING STABILIZED PAVEMENT COMPONENTS.
Abstract
An investigation was conducted to determine the manner and extent to which stabilized materials can be utilized in airport pavement components which include the subgrade, subbase, and base courses. The investigation was primarily limited to a review of existing knowledge of soil stabilization and pavement thickness design practices. Some additional research was necessary to provide additional data where information from published sources was lacking or sparse. Recommendations are advanced in regard to thickness design and quality requirements when stabilized materials are incorporated into the pavement. An attempt was made to duplicate the existing FAA design criteria as much as possible thereby resulting in a minimum amount of change. Basically, this objective was accomplished in that the required pavement thickness is still determined by the present curves for flexible and rigid pavements and the thickness is then adjusted in certain cases to account for the stabilized component. It was necessary to introduce a bearing strength test (unconfined compression test) for the higher levels of stabilization to rate the effectiveness of the stabilizing agents in producing pavement components of sufficient quality.
