Structural Evaluation of Cellular Plastic as a Base Course Material for Expedient Pavements.
Abstract
This report is concerned with the development and structural analysis of a new pavement concept for military expedient pavements. Advanced tactical mobility concepts require a non permanent, quickly constructed and easily repaired airfield pavement system which can successfully withstand a limited number of aircraft coverages. Such pavements are referred to as expedient pavements. The concept presented considers the use of plastics as a construction material for expedient pavements. These all-plastic pavements consist of a thin (0.5-inch) wearing course fabricated from a tough and durable fiberglass reinforce polyester having very high strength properties, and a cellular plastic base course placed directly upon the subgrade. For purposes of this study, rigid polyurethane was used as the base course material simply as a means of providing strength data for the structural analyses. The study demonstrates the feasibility of the concept of an all plastic system for expedient pavements and suggests additional research and development programs so as to further develop the concept.
