Data describing the condition of physical facilities, such as bridges and pavements, provide the foundation for decisions about maintenance and rehabilitation. Condition data are collected and reported using a variety of technologies, with varying levels of error, uncertainty, and cost. Agencies practicing effective asset management would like to minimize lifecycle costs for their facilities; condition assessment affects lifecycle costs both directly (through the cost of collecting and analyzing the data) and indirectly (through the actions taken in response to the condition assessment). In addition to agency costs, user costs are affected as well. Uncertainty in pavement condition assessment can have significant effects on average network condition and lifecycle costs. Specifically, the work described uses simulation of pavement deterioration and rehabilitation to track pavement condition and associated maintenance and rehabilitation costs over time. Scenarios evaluated include uncertainty due to systematic errors as well as random variation. Finally, the paper reports the results of a statistical evaluation of the simulation scenarios.
