Abstract
Mechanistic empirical (M-E) pavement design methods have been available for practice since the late 1970s, and many agencies use them for design and analysis of new pavement and rehabilitation projects. The mechanistic part has typically been based on mechanics and laboratory testing, sometimes validated with data from well-instrumented accelerated pavement test (APT) sections. The empirical transfer functions have traditionally been calibrated with small numbers of field sections from which materials properties have been sampled. This paper presents a new approach for calibration, that provides better compatibility with pavement management systems and future use of performance related specifications.
