CALIBRATION OF HDM-4 BITUMINOUS ROAD DETERIORATION MODELS FOR INDIAN CONDITIONS

The Highway Development and Management model (HDM-4) is a support system for decision making for highway administrators and engineers to predict the economic, social, and environmental impacts that might occur while making investment decisions. The purpose of this paper is to show the principal used for calibration of HDM-4 road deterioration model is to model past behavior and compare the model's predictions with present day measurements in order to adjust it to real conditions prevailing at the location of its use. The road deterioration models contained in HDM-4 attempt to model the complex interaction between vehicles, the environment, the pavement structure and surface. The road deterioration models predict the deterioration of the pavement over time and under traffic, which is manifested in various kinds of distresses. But, as each mode of distress develops and progresses at different rates in different environments, it is important that the HDM-4 relationships should be calibrated to reflect local conditions and to ensure their relevance to techno-economic analysis of maintenance and rehabilitation alternatives of road networks, situated in a particular geographical region.
