RELIABILITY DESIGN PROCEDURES FOR FLEXIBLE PAVEMENTS

The paper presents a design methodology with the capability of considering design-parameter variability in the U.S. Corps of Engineers' design procedure for flexible airfield pavements using the elastic, layered method. The design procedure is expressed in probabilistic and reliability terms. The designer can select the pavement thickness, and in some cases, develop an overlay design scheme based on the desired reliability level. The design procedure is incorporated in a computer program. With use of the procedure, the partial effect of the variability of each design parameter on pavement performance can be investigated, and its effects on the final design can be quantified. It is possible to place emphasis on the crucial parameters that are to be tightly controlled in the construction phases, and the crucial loading parameter dictated by the intended use of the pavement.
