Reliability Evaluation of Pavement Life-Cycle Assessment Model
Inventory reliability of the life-cycle assessment (LCA) model highly depends on the data quality and normally exhibits significant uncertainty. A rigorous statistical methodology was established to capture and quantify the inherent uncertainties linked to the results of the LCA model. Two sources of uncertainty data quality and model were identified. The former was captured by converting

DEVELOPMENT OF A PAVEMENT LIFE CYCLE ASSESSMENT
1.1.2 Introduction to Life Cycle Assessment Life cycle assessment is another type of environmental assessment that evaluates the entire life cycle of a system in order to give numerical results characterizing the system s environmental impacts. For example in a pavement system five life cycle phases are often considered (Santero 2009).
