The use of resilient models to describe the behavior of the materials in pavement design is the current standard. However, there are periods of the year when these resilient models may not be valid. Granular materials in pavements show some resiliency at every load level and moisture content. Nonresiliency is critical, however, when the plastic deformation becomes a large portion of the overall deformation in response to a load. Detection of possible nonresiliency in a pavement during use of a falling-weight deflectometer (FWD) would alert the FWD operator to possible nonresilient behavior. Two statistical checks are proposed to test for nonresiliency using the raw data provided by the FWD. Daily testing of a very weak pavement during spring thaw provided FWD data during and after a period of known nonresilient behavior. A chi-squared test of the variance may be able to detect nonresilient behavior.
