With the growing popularity of mechanistic-empirical design concepts, a need exists to address design in an unbiased manner that incorporates the natural capability of these concepts to provide designs for any region, soil type, or environmental condition on a comparative basis. With these possibilities within reach, the calibration of these designs consequently stands out as a key ingredient to the successful application of their results to actual performance standards. Design calibration can be determined such that reliability coefficients are not unduly biased. On the basis of this premise, design calibration applies to both design and reliability parameters and as a consequence is influenced by the intrinsic material and structural characteristics germane to different pavement types and climates. With this perspective of mechanistic design concepts, the age of subjective factors of safety in pavement design has long since passed. The full benefit of using rational, mechanistically based reliability and calibration factors may be realized only when these factors consider the "underlying" mechanisms relative to the development of pavement distress. The analysis of pavement performance data conducted on this basis provides insight and understanding that reflect the type of mechanisms noted earlier and leads to the greatest utility of design model calibration efforts.
