Book Description
Several different methods of pavement network rehabilitation management are compared. These methods range from random selection, to worst first ranking, to different methods of optimization. The results of applying each method on a sample highway network show for the first time, greatly different benefits and overall performance for the same budget expenditure. Optimization methods provided the best network performance over other methods, however, different optimization methods provided comparable results. The needs method provides a reasonable estimate of pavement rehabilitation needs when the network budget is unlimited. Incremental benefit-cost ratio algorithm is found to be a very efficient and practical algorithm for use in pavement management system (PMS). An objective benefit function is also recommended for use in the network-level PMS.

Book Description
The Illinois Interstate highway network is deteriorating rapidly due to its age and heavy truck loadings. Unfortunately, the funds required for rehabilitation far exceed the available funds. The Illinois Department of Transportation (IDOT) faces many difficult decisions concerning prioritizing rehabilitation projects and anticipating future pavement conditions and rehabilitation needs. To assist IDOT in making these decisions, three analyses were conducted using the ILLINET pavement network rehabilitation management program. The first of these was an analysis of the accuracy of ILLINET' s pavement condition prediction models. The second was an analysis of the remaining life of each of the more than 1200 pavement sections in the Illinois Interstate network. The third was a comparison of the rehabilitation needs predicted by ILLINET to IDOT' s latest multi-year program. The results of these analyses are of immediate practical use to IDOT in forecasting pavement rehabilitation needs for individual pavement sections, Interstate routes, and the entire Interstate network.
