ABSTRACT
A Life-Cycle Cost (LCC) based Remaining Service Interval (RSI) methodology is demonstrated using a project-level pavement management application. Treatment type selection in the methodology is centered on expected performance of the pavement system as a whole and is a function of pavement condition, both functional and structural, at the time of treatment application. Data collected as part of the Long-Term Pavement Performance program were used to demonstrate the methodology on an asphalt pavement section in California. Treatment efficacy was evaluated using the CalME program. The analysis showed that classical tensile strains can be used as a leading structural indicator and they have good correlation with deflection indices. The proposed methodology will allow agencies to optimize their treatment selection process and to communicate stakeholders, succinctly and with clarity, when and what treatments are needed for each segment within their network to achieve and maintain state-of-good repair at a minimum practical LCC.
