This presentation explains the Metropolitan Transportation Commission's (MTC) effort to improve its pavement management system. It seeks to first improve its data quality and consistency through a Data Quality Management Plan that will provide pavement engineers with adequate training and skills to more thoroughly analyze pavement conditions. It outlines the process for the certification of these engineers.

This presentation is a summary of the Interstate Condition Project overseen by Amec, Foster, Wheeler. It begins by giving background on MAP-21 and the Interstate Condition Project. It then analyzes the collected data using a variety of methods. Finally, it summarizes the findings, weighing their merit and what information it accurately portrays.

This presentation analyzes the effect of climate change on pavement life cycle costs. It begins with an overview of our changing climate–the motivation for this study–and then transitions into the methods used for the study. The study used a number of programs and data collection methods to aid in its predictions. As a result, it found that climate change accelerates deterioration and will increase life-cycle costs.

This presentation discusses the Michigan DOT's effort to integrate climate risk into their transportation asset management plan. It begins by identifying assets at risk as well as climate variables such as temperature, and precipitation. It then uses this information for a statewide risk analysis on bridges and roadways, noting particularly at-risk areas such as Trunkline, Pump, and Culvert.

This presentation focuses on bridge data analysis in the state of California. It uses National Bridge Inventory (NBI) data to analyze the strength and serviceability of California bridges while also analyzing the correlation between location, material, traffic volume, and age. It concludes with general trends found in research and a review of difficulties with use of the program.

This presentation focuses on the National Bridge Investment Analysis System (NBIAS) and its uses for transportation agencies. It first gives background on the NBIAS software, followed by an explanation of how it analyses bridges to evaluate risk. The software analyzes safety, infrastructure condition, congestion and reliability, economic vitality, and environmental sustainability and identifies an annual investment plan.

This presentation focuses on improving understanding of bridge deterioration and maintenance. It begins by defining three types of deterioration– native deterioration, post-rehabilitation deterioration, and impact of preservation on deterioration– and strategies for condition predictions. It continues to explain how risk incorporation can further aid decision making and funding allocation.

This presentation focuses on bridge management in the 21st century. It beings with a case study of the Auckland Harbor Bridge in New Zealand. It identifies the issues with the bridge and recommends a robust maintenance strategy that takes into account the budgetary limitations of the 21st century. It then expands on these strategies to encompass bridge programs more generally.

This presentation addresses the question of how governments should prioritize road repairs given limited resources. It reviews common prioritization practices including cost effectiveness, worst first,and a number of benefit cost assessments. It concludes optimal prioritization methods depend on agency goals and use of multiple models will help to trade-offs involved.

This presentation focuses on two topics– life cycle cost analysis for bridges and return on investment. It discusses the technology and strategies used in bridge life-cycle cost analysis including costs broken down by treatment. It also analyzes bridge investment strategies for State DOTs.

This presentation focuses on the Life-Cycle Strategy Analysis for bridge decks. It begins by giving background on bridge deck cracking and the objectives driving this initiative such as identifying symptoms of early-age cracking and identify the most effective remediation practices for concrete bridge decks. It then explains current remediation practices and their associated costs. It concludes by noting how Life-Cycle cost analysis during construction and design can lower the required number of remediation treatments and thus lowering the LCC .

This presentation given at the 11th National Conference on Transportation Asset Management provides insight into bridge maintenance cost models based upon asset condition data. MnDOT retrieves bridge data from multiple sources and then combines it using a business intelligence tool. However, within this process MnDOT faces the challenges of data quality, system integration, and accurate development of life cycle cost analysis for bridges.
