Optimization of Long Range Major Rehabilitation of Airfield Pavements
Abstract
This technical report develops a methodology for managing pavement networks over prolonged analysis periods. Separate independent methods are devised for project and network level analysis, and the project level procedures are designed to provide inputs to the network level procedures. The project level analysis procedures optimally select and schedule major rehabilitation activities (routine maintenance, reconstruction, and overlays) over an extended analysis period. A computer code was written to use dynamic programming methods to optimally select schedule activities over the analysis period (20 years), by maximizing the structural performance AREA UNDER THE UTILITY WEIGHTED Pavement Condition Index (PCI) versus time curve. These results can be used by decision makers and pavement engineers to help decide which rehabilitation activities should be considered and when to schedule them. The network level analysis procedures select, from the group of projects developed either with dynamic programming or by other methods of the engineers' choosing, those projects that maximize the sum of the user value weighted structural performance of each project. Keywords: Management; Optimization; Dynamic programming; Airfield.
