Abstract
The Illinois Interstate highway network is deteriorating at a rapid rate due to its age and heavy truck loadings. Meanwhile, the required funds for rehabilitation far exceed the available budget. Illinois DOT administrators and planners are faced with many difficult questions about the consequences of adopting different pavement rehabilitation budgets and policies. To answer these questions, they need information about future rehabilitation needs and pavement conditions for different funding levels and rehabilitation strategies. The Illinois pavement net work rehabilitation management program (ILLINET) was developed to provide this capability to aid IDOT administrators and planners. The program generates useful results on a personal computer in both summary tables and graphics.
The objective of this study was to develop a network rehabilitation management program (ILLINET) to aid IDOT districts and central offices in pavement management decision making for the Illinois Interstate highway network. This program analyzes data regarding pavement, traffic, climate, and other factors to provide answers to critical questions often asked about the network at the planning and administration level before budget allocations are made. ILLINET will also provide IDOT with the optimum rehabilitation program for a certain budget, and also the minimum budget required to maintain the Illinois Interstate network in a desired condition. ILLINET is a totally interactive computer program with user friendly menus and graphics.
"The development of ILLINET includes the use of available predictive models and development of other models needed. Specifically, systems are developed to: (1) Provide a variety of methods to generate feasible pavement rehabilitation strategies (treatments and timings) for each pavement section in the Illinois Interstate network over a period of up to 10 years. (2) Provide several network management algorithms and several ways of defining ""benefits"". (3) Determine the overall rehabilitation program for a selected budget or the budget required to maintain the network condition at a desired level. (4) Provide answers for a variety of ""what-if"" questions which are asked before a policy is adopted or budgets are allocated for the rehabilitation of pavements. (5) Analyze the consequences of different project-level, network-level, and benefit options on network performance and cost."
