The pavement remaining service interval (RSI) terminology was formulated to remove the confusion caused by the multitude of meanings assigned to the various forms of pavement remaining service life (RSL) terminology. The RSI concept considers the complete maintenance and rehabilitation activity of the pavement system and does not simply consider the end of life as promulgated by the RSL philosophy. This report answers the following questions: should the time until a condition exceeds a threshold, or the optimum time to apply a rehabilitation treatment is reached, be used as the basis for rehabilitation RSI? When the condition of a pavement drops to a level that is lower than the reconstruction threshold, should a negative RSI be reported? This report provides more evidence of merit to move the pavement community away from a worst first approach and toward a more optimal mixture of pavement preservation and rehabilitation treatments based on proper consideration of lifecycle cost concepts. The project- and network-level analyses presented in this report represent an important milestone in the evolution of pavement and asset management systems. This report is intended for use by pavement management engineers and pavement investment decisionmakers across the United States.

| 16. Abstract
The pavement remaining service interval (RSI) terminology was developed to remove confusion caused by the multitude of meanings assigned to the various forms of pavement remaining service life (RSL). The RSI concept considers the complete maintenance and rehabilitation (M&R) activity of the pavement system and does not simply consider the end of life as promulgated by the RSL philosophy. The goal of this project was to demonstrate and further develop the application of the pavement RSI concept using real data from two State pavement management systems and the Highway Performance Monitoring System 2010+ dataset. Project-level analysis addressed gaps in the network- and strategic-level analyses. The results from the validation efforts support the conclusion that the RSI represents a valid approach to determining and communicating future M&R needs of a pavement instead of defining pavement life using a single number as in RSL. Those results also show that RSL is essentially not related to the time until the next pavement treatment in an optimal strategy. |
