Highway Development and Management Model (HDM-4): calibration and adoption for low-volume roads in local conditions

Abstract

Pavement deterioration models help in predicting the condition of the pavement at a future date. These models form an important input in a pavement management system for assessing the state of health of pavements and for selecting the optimal maintenance and rehabilitation strategies. The model HDM-4 developed by the World Bank is used for pavement management activities and must be adjusted to the specific conditions of the country or region where they are to be used by adjusting certain calibration factors. In this study, an attempt has been made to calibrate HDM-4 pavement deterioration models for paved low-volume roads (LVRs) in India by using the ‘window’ monitoring techniques. Pavement condition data of in-service LVR sections are collected for a 2-year period for model calibration, and the calibrated models are validated. The result of this study will be a useful input for deciding optimal maintenance strategies (type and timing) for LVRs in India.
