HDM-III Model-Appropriate Pavement Maintenance and Rehabilitation Programs Under Conditions Prevailing in Central European Countries

The study of possibilities for using the Highway Design and Maintenance-III /HDM-III/ model to optimize selection of appropriate pavement maintenance and rehabilitation programs under conditions prevailing in Central European countries is presented. The analysis was carried out on a part of the South Bavarian road network, and it is the first attempt to apply the HDM-III model for optimizing road maintenance and rehabilitation in this West European country. The tesults obtained clearly point to the numerous advantages of using HDM-III model, if regional specificities are realisticlly presented. Particular emphasis is placed to the great number of input parameters used as a basis for modeling, including the possibility of error in defining individual values of so many parameters. The influence of various parameters on the performance of the model is analyzed in detail. This task is performed in the context of a sensitivity analysis of the HDM-III model. The analysis justifies the global ranking of input data according to their importance in the HDM system.
