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 …
