Effect of pavement surface properties on life cycle cost analysis
Life Cycle Cost Analysis (LCCA) is one of the most well established methods used in determining the best alternative pavement project. The two main pillars of LCCA are user costs and agency costs. User costs are incurred during normal transportation operation and when there is a work zone present. …

Incorporating uncertainty in the Life Cycle Cost Analysis of pavements
Life Cycle Cost Analysis (LCCA) is an important tool to evaluate the economic performance of alternative investments for a given project. It considers the total cost to construct, maintain, and operate a pavement over its expected life-time. Inevitably, input parameters in an LCCA are subject to a …

Effectivess of Using Geotextiles in Flexible Pavements: Life-Cycle Cost Analysis
… from an economical point of view, a complete life cycle cost analysis (LCCA), which includes not only costs to agencies but also costs to users, is urgently needed to assess the benefits of using geotextile in secondary road flexible pavement. In this study, a comprehensive life cycle cost …
-
A life cycle cost based methodology for choosing among design alternatives
A life cycle cost based methodology for choosing among mutually exclusive design alternatives is presented in this study. The methodology places emphasis on the iterative nature of the design process. That is, choosing among design alternatives involves the pairwise comparison of the current design …
