Book Description
Transportation agencies seek to optimize their public budget to finance the construction and maintenance of pavements. Life Cycle Cost Analysis (LCCA) is a decision support tool that allows agencies to contrast and optimize infrastructure design alternatives based on the costs of the asset over its lifetime. In this thesis, statistical distributions were developed to study the variability associated with LCCA inputs based on agency historical data of the Province of Manitoba and the City of Winnipeg. A case study was used to compare the deterministic and the probabilistic computational approaches results. The results demonstrated that a probabilistic LCCA provides reliability levels for the evaluation of the total project cost, which allows for analyzing the risk associated with each alternative and avoiding cost overruns. It is recommended that transportation agencies consider probabilistic LCCA as part of their decision-making process due to the economic benefits and reliability levels that this approach provides.

Book Description
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 high level of uncertainty, both in the short-term and long-term. Under its current implementation in the field, however, LCCA inputs are treated as static, deterministic values. Conducting such an analysis, although computationally simpler, hides the underlying uncertainty of the inputs by only considering a few possible permutations. This suggests that although computationally simpler, the answer from the analysis may not necessarily be the correct one. One methodology to account for uncertainty is to treat input parameters as probabilistic values, allowing the analysis to consider a range of possible outcomes. There are two major reasons as to why probabilistic LCCAs, although recommended, have not been streamlined into practice. First, the LCCA of construction projects is a large-scale problem with many input parameters with a high-level of uncertainty. Second, there is a significant gap in research that statistically quantifies uncertainty for input values. This research addresses the latter point by statistically quantifying four types of uncertainty: the unit cost of construction, quantity of material inputs, occurrence of maintenance activities, and a particular emphasis is placed upon characterizing the evolution of material prices over time. Having statistically characterized uncertainty in the LCCA analysis, the application of the probabilistically derived inputs is illustrated in three scenarios. Pavement alternative designs are derived for a set of traffic conditions in a given location. The results of the analysis indicate the integration of probabilistic input parameters in the LCCA process allows for more robust conclusions when evaluating alternative pavement designs. Additionally, the case study shows treating input parameters probabilistically could potentially alter the pavement selection, and one parameter that greatly influences this is material-specific price projections.

Book Description
This report provides an outline for the engineer seeking to conduct a Life-Cycle Cost Analysis (LCCA) in pavement design and selection. The guidance, recommendations, and default values provided here were collected from 10 years of paving projects. Most of these projects were constructed or rehabilitated in the mid 1980s in order to evaluate the current design and construction practices in the State of Colorado. At this time, the Colorado Department of Transportation uses a deterministic approach to the LCCA and is researching the move toward a probabilistic LCCA.
