Reliability Considerations of Airport Concrete Pavement Design Using Variation of Backcalculated Modulus

The F/HWD Round-Up project located at the Federal Aviation Administration’s (FAA) National Airport Pavement Test Facility (NAPTF) at William J. Hughes Technical Center near Atlantic City International Airport, NJ, U.S., was constructed to investigate the variation of NDT data and FAARFIELD1.42 based on sound theoretical principles and with models verified from appropriate full-scale test data. This paper presents a case study of how the uncertainty of backcalculated in situ modulus can be assessed and incorporated in the FAARFIELD1.42 design procedure to determine appropriate concrete pavement thicknesses. The mean values and standard deviations of backcalculated modulus were computed using two computer programs: BAKFAA (layer elastic theory) and 1993 AASHTO design guide (plate-on-grade theory), and then input into FAARFIELD1.42 using Rosenblueth’s procedure to predict the reliability of a 20-year pavement design performance. The case study shows that the proposed procedure provides an alternative decision-making tool for airport engineers to predict pavement life more realistically using F/HWD data.
