CALIBRATING HDM-4 RUTTING MODEL ON NATIONAL HIGHWAYS IN JAPAN

This study mentions results of calibrating HDM-4 rutting model on Japanese national highways and comparing HDM-4 rutting model with rutting prediction model included in MLIT-PMS (Pavement Management System developed by Ministry of Land, Infrastructure, and Transportation of Japan). It is found that as far as rut model is concerned, HDM-4 is more applicable to real phenomenon than MLIT-PMS in both dense-graded asphalt concrete pavement and porous asphalt pavement. However it is necessary to perform further verification of HDM-4 models together with continuing accumulation of relevant field data.
