Abstract
Concrete pavements, underdesigned for today's levels of traffic, are deteriorating rapidly. Maintenance, rehabilitation, and reconstruction activities (MRR) have become more widespread and costly. State highway agencies are often being asked to do more MRR work with fewer funds. An improved and comprehensive decision process for selecting the preferred strategy for MRR that considers not only pavement but also traffic and construction issues is needed. Research was conducted to develop a framework for selecting strategies for MRR. The factors, steps, and information involved in the MRR decision process were identified. A decision analysis tool, IDEF0, was used to model the decision process framework. The IDEF0 model is hierarchical in nature (each function is divided into subfunctions) and includes the information flow between the different functions. Data was collected through project case studies and interviews to evaluate and refine the framework. Further research will be necessary to expand the model to a higher level of detail.
