Various general models have recently been used in an engineering-economic study to determine the road maintenance efficacy of the interurban road network in israel. These models contain deterioration curves for various maintenance and rehabilitation policies, togetherwith the preparation and overlaying costs, routine maintenance costs, and road users' costs, all as a function of overall pavement grade values. These models led, after the determination of an overlayingpolicy, to establishment of a purposive model for computing a priority ranking as a function of various parameters. The model obtained was found to be sensitive mainly to the annual average daily traffic.
