DEVELOPMENT OF A THICKNESS DESIGN PROCEDURE FOR STABILIZED LAYERS UNDER RIGID AIRFIELD PAVEMENTS. PROCEEDINGS, 4TH INTERNATIONAL CONFERENCE ON CONCRETE PAVEMENT DESIGN AND REHABILITATION, PURDUE UNIVERSITY, APRIL 18-20, 1989

This paper presents the development of a design procedure for the determination of the thickness of a cement treated base (CTB) under a rigid pavement system. The procedure is based on an equivalent interior stress criteria. Allowance is made for the determination of the allowable pass level on the CTB material. A computer program was developed in conjunction with the study. The procedures were developed using the stress results from an elastic layer analysis in the form of the BISAR program. The method was structured around the existing Federal Aviation Administration (FAA) design procedures and is completely compatible with the current design procedures. From a design point of view the benefit to this analysis procedure is that the designer is allowed to utilize the materials properties of the CTB. In areas where CTB is a common construction material or for large projects, the reductions in concrete thickness and replacement with a higher quality CTB may provide an opportunity for economic savings. Also, the designer is provided with information regarding the allowable pass level on the CTB material. This information is not presently provided in any conventional design method.
