Reliability considerations of bituminous pavement design by mechanistic–empirical approach

The reliability issues in bituminous pavement design, based on mechanistic–empirical approach, have been discussed in this paper. Variabilities of pavement design input parameters are considered and reliability, for various proposed failure definitions, of a given pavement is estimated by simulation as well as by analytical (first order second moment) method. A methodology has been suggested for designing a bituminous pavement for a given level of overall reliability by mechanistic–empirical pavement design approach.
