A STUDY ON CREATING METHOD OF PERFORMANCE CURVE USING PAVEMENT DATA BASE IN MLIT-PMS

Satoshi TANIGUCHI, Masahide ITO, Toshiaki NOMURA and Tadayuki ABE

In order to estimate life-cycle costs properly, pavement performance curve suitable to analysis period is indispensable. This study mentions performance prediction model created from Pavement Data Base. To establish the model, the method was proposed how to presume the relative frequency and mode of road surface conditions at the time of assuming that repair was not conducted. . Appropriate standard performance prediction model about cracking, rutting, and evenness was attained in this procedure. And estimating life cycle cost was available for network level using this model.
