This book was released on 2017 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proper implementation of pavement preservation techniques can extend the life of a pavement structure in a cost-effective manner. For this reason, a large part of the Texas Department of Transportation (TxDOT) annual budget is assigned to the maintenance and rehabilitation of the State highway network. Within this budget, a fair share is allocated to the implementation of preventive maintenance (PM) techniques, whose timely application has proved the best approach to keep the pavement sections in “Good” or “Very Good” condition. The main objective of this research study was to develop a probabilistic life-cycle cost analysis (LCCA) that allowed the evaluation and comparison of highway pavement sections subjected to one of the three main PM treatments used in Texas, namely, chip seals, microsurfacing and thin overlays. Effective life and the cost per mile lane were the main variables used to develop the analysis. The analysis was performed through Monte Carlo Simulation using data from TxDOT databases containing historical information on more than 14,000 projects constructed between 1994 and 2016. Because TxDOT maintains a plethora of information on its databases, the methodology to use those databases and to extract the relevant information used in this study was also described. During the study, the effect of the facility type, traffic volume and traffic loads on the treatments were also analyzed. Based on the results of the analysis, it was established that all three treatments present a similar service life regardless of external factors, but have different costs, with chip seals having the lowest, followed by microsurfacing and thin overlays. Findings suggest that chip seals have the most cost-effective LCC, even in environments where they are not commonly employed, like heavily trafficked sections. However, microsurfacing emerges as an interesting alternative as traffic volumes and traffic loads increase. Finally, thin overlays are to be evaluated in a case-by-case basis as they have the less predictable behavior. This is most probably consequence of being the newest type of treatment, having the steepest learning curve. They could work well in pavement sections located in intersections, turning points and stop signs, where higher shear stresses are involved.

Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to highway agency executive management including administrative, budget, and finance personnel; pavement design, construction, and maintenance engineers; and maintenance operations personnel, including supervisors and maintenance crew leaders. This synthesis describes the state of the practice with respect to setting a coherent strategy of cost-effective preventive maintenance for extending pavement life. This report of the Transportation Research Board describes the practices of state, local, and provincial transportation agencies that are attempting to minimize the life-cycle costs of pavements and are identifying, during the design of the pavement rehabilitation, reconstruction, or construction projects, the future preventive maintenance treatments and the timing and funding for those treatments. It includes a review of domestic literature and a survey of current practices in North America. The appendices include a primer on pavement design and construction, the benefits of preventive maintenance of pavements, a summary of the questionnaire data collected, a simulation of pavement management strategies, and an example process to demonstrate the cost- effectiveness of preventive maintenance.

Download or read book Incorporating Uncertainty in the Life Cycle Cost Analysis of Pavements written by Omar Abdullah Swei and published by . This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
