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 …

Life cycle cost analysis of asphalt and concrete pavements
This report describes a life cycle cost analysis (LCCA) for road pavements and evaluates its impact on pavement type choice. Working from literature, historical data and interviews, the LCCA technique is described and an overview of the road and street system in Iceland is presented. The LCCA …

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. …

An economic evaluation on FRP for bridge construction in South African coastal areas
… to predict these life cycle costs by employing a LCCA. The research aim was to investigate the economic viability of using FRP as reinforcing elements in bridge construction. This was done by conducting a life cycle cost analysis (LCCA) on two highway beam bridge superstructure designs: a SRC …

Alternatives to PCI and MicroPAVER based maintenance solutions for airport pavements
… Moreover, the Life Cycle Cost Analysis (LCCA) determines the best option based on the minimum life cycle cost assuming all alternatives have equal functional benefit. By only performing LCCA, one cannot draw a conclusion about the functional benefit achieved by an alternative. A pavement …

A Framework for Holistic Life Cycle Cost Analysis for Drinking Water Pipelines
Life Cycle Cost Analysis (LCCA) forms an important part of asset management practices and provides an informed decision support. The holistic nature of LCCA includes life cycle assessment (LCA) as an important component alongside economic life cycle cost analysis. The drinking water industry is …

Overcoming code rot in legacy software projects
… This thesis presents the application of the LCCA (Legacy Code Change Algorithm) on the legacy MOOCdb translation software project to solve its code rot and make it maintainable. The evaluation is based on the rate at which issues were resolved during different stages of LCCA, and an analysis …

A more comprehensive life cycle cost analysis of pavement materials alternatives
Life Cycle Cost Analysis (LCCA) is a commonly used tool in analyzing the economic viability of highway construction investments. The initial and life-cycle materials costs associated with highway construction involve a high level of uncertainty and therefore warrant extensive and dynamic cost …
