Summary: Possibilities for practical application of the management systemfor road maintenance and pavement renewal within the road networkof Croatia are analyzed in the project. In the scope of this task, the number of road-related datanecessary for applying the management system (terminology, type of data,collection method, consistency and accuracy of data)will be defined. In order to develop and implement the management system for maintenance of road pavements,it is necessary to develop new orto critically analyze existing models for selecting optimummaintenance strategies. For the conditions prevailing in Croatia, the HDM-III model(Highway Design and Maintenance Standards Model), developed fordeveloping countries by the Internaational Bank forReconstruction and Development from Washington, seems to beparticularly interesting. In this research, the emphasis is placed on the evaluation ofpossibilities for using the HDM-III model in real roadconditions, taking into account road traffic parameters andclimatic conditions in individual regions of the Republic of Croatia.

Research goals: The main objective of this research is to define a minimum amount of basic(and optional) road and traffic information, necessaryfor the practical application of the management system in theroad maintenance and renewal. In addition to other requiredpreconditions, this would enable the road authority to bringfinancially sound and technically correct decisions for planningmaintenace, renewal and reconstruction activities within the roadnetwork. In that respect, it is necessary to quantify, in thescope of this research, to what extent individual factor (such astraffic load, climatic conditions, material properties and theirmodifications, construction quality, maintenance level) influencedeterioration and behavior of the existing road pavements. Results of this research are extremely signaficant for the finaldevelopment and practical use of the management system in theroad maintenance and renewal in Croatia as, by its structure,this system would enable the Croatian road authority to introducea novel approach to the road planning and maintenance policy. It is therofore quite certain that the research results willdirectly be applied in practice. It is also quite evedent thatthe implementation of results obtained through this research willsignaficantly contribute to the increase in quality of roads andtransport flows, and to the reduction in harmful effects of roadsand road traffic on the environment.
