Incorporation of Reliability into Airport Pavement Design Using Backcalculated Pavement Layer Moduli

Currently, several variations of Falling or Heavy Weight Deflectometer (F/HWD) equipment exist on the market. The Federal Aviation Administration (FAA) National Airport Pavement Test Facility (NAPTF) Round-Up project provided an opportunity to examine different market available F/HWD equipment. This paper presents a case study of how the uncertainty of backcalculated in-situ moduli can be assessed and incorporated in the FAA Rigid and Flexible Iterative Elastic Layer Design (FAARFIELD) design procedure to determine appropriate pavement thicknesses. The mean values and standard deviations of backcalculated layer moduli were computed and then input into FAARFIELD using Rosenblueth’s procedure to predict the reliability of a 20-year pavement design performance. The research shows that the proposed procedure can be used as an alternative decision-making tool for airport engineers to more realistically predict pavement life using F/HWD data.
