Cost Benefit Analysis of Thin Surface Treatments in Pavement Treatment Strategies Cycle Maintenance

摘要

In this study, a cost-benefit analysis was performed to select the most economical alternativeamong various pavement preservation choices using life cycle cost analysis (LCCA) analyticaltechnology. The impact of pavement conditions on the performance of the specific treatment wasinvestigated in terms of pavement performance curves, which were developed for the treatmentsunder varying pavement condition levels at each traffic network based on the PennDOT OverallPavement Index (OPI) data. A relationship between pavement life extension and pavementcondition prior to the treatment was established. Finally, LCCA was conducted to quantify theimpact of the pavement condition on the performance of the preservative treatments in terms ofbenefit cost (B/C) ratio and net equivalent uniform annual cost (ΔEUAC). Results indicated thereis an optimum pavement condition, and associated age (or a range of condition or age) when thebenefit cost associated with a treatment is maximized.
