Prediction models for pavement deterioration of major roads in Miyazaki Pre-fecture, Japan, using falling weight deflectometer (FWD) data are presented. The models would be incorporated in a pavement management system (PMS), for the prefecture, which is under development. At first, a relation between Japanese maintenance control index (MCI) and cumulative equivalent single axle loads (CESAL) wa…
A study on dynamic backcalculation and overlay design based on falling weight deflectometer (FWD) data is presented. Dynamic slab-ground theory (DSGT) was used for dynamic backcalculation of a pavement structure. A computer program based on DSGT generated theoretical dynamic deflections of the pavement. For the backcalculation of equivalent full-depth asphalt concrete (AC) thickness and subgrad…
