Available in PDF, EPUB and Kindle. Book excerpt: A computerized method has been developed to conduct network optimization analysis. The analysis uses performance models along with life-cycle cost analysis to identify the most effective treatment to be applied for a specific pavement section. Performance models were developed for the most common maintenance treatments: sand and chip seals, and rehabilitation treatments: overlay, roadbed modification, and mill and overlay. The models were developed using actual pavement management data collected on field sections for the past 15 years. The life-cycle cost analysis uses the present worth approach along with actual cost figures for initial and annual construction activities. The individual treatments are used to create alternatives that can provide the acceptable performance level for a given pavement section over the entire analysis period of 20 years. The annual performance of pavement sections is modeled in terms of the present serviceability index (PSI). The most effective treatment alternative is selected based on the highest benefit cost ratio which is defined as the ratio of area under the PSI versus time curve divided by the total cost of the alternative. Once the most effective alternative is selected for each pavement section, a summary of the annual expenditures is provided for the group of pavement sections that have been selected for analysis. The group of projects can be the entire network or a group of pavement sections that have been selected by the engineer.

Available in PDF, EPUB and Kindle. Book excerpt: Optimal use of pavement maintenance and rehabilitation dollars is essential in a constrained budget environment such as now. A network-level optimization tool, which could generate the best maintenance and rehabilitation strategies for the entire pavement network, has become necessary for many highway agencies. This thesis presents the development and implementation of a network-level optimization tool within a pavement management information system for the Ohio Department of Transportation (ODOT). Future pavement condition is predicted based on historical pavement data using a Markov transition probability model. Such transition probabilities are updated automatically when new condition data become available each year. The network-level optimization tool integrates a linear programming model and the Markov transition probability model. This optimization tool is capable of (1) calculating the minimum budget required to achieve a desired level of pavement network condition, (2) maximizing the improvements of pavement network condition with a given amount of budget, and (3) determining the corresponding optimal treatment policy and budget allocations. It can be used by highway agencies as a decision support tool for network-level pavement management.

Download or read book Prioritization Optimization Process Algorithm to Manage Pavement Networks During the Non Availability of Historical Data written by A. Kitaha and published by . This book was released on 2016 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common practice followed to rate the pavement surface condition is to use the ASTM D5340-12 procedure and estimate the pavement condition index (PCI) that helps prioritize maintenance needs and assists developing a pavement management system (PMS). However, ASTM-PCI that is dependent on time-based evaluation may not be suitable where there is a lack of historical records and it is being undertaken for the first time. To estimate a pavement's current PCI during the non-availability of historical data and establish a PMS incorporated with prioritized maintenance and optimized budget, a rational engineering criteria (EC) based methodological approach is required that is as robust as ASTM D5340-12. Thus, the objective of this study was to develop a rational EC-based prioritization-optimization process PMS (POPMS) algorithm for a network that prioritizes maintenance strategies for identified pavement distresses and hence optimizes maintenance costs depending on budgetary allocations. An EC-based POPMS algorithm was based on a network length of 100.55 km, which followed prioritization-optimization process for single to multi-year programs. EC-PCI of pavement sections were estimated on the basis of segmented maintenance strategies including preventive and routine maintenance and reconstruction. EC-PCI was found to be rational since three distinct threshold zones were considered that could directly assign pavement maintenance strategies, which was straightforward and circularly referenced. Overall, POPMS algorithm facilitates practitioners to modify the threshold EC-based parameters that will estimate an optimal single/multiyear budget for maintenance as per the newly set threshold level, thus creating a whole new promising approach in the areas of roadway network level maintenance programs.

This book was released on 2019 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: State Departments of Transportation (DOTs) are trying to utilize the best practices of managing low-volume roads (LVRs) due to limited resources and declined transportation funding. Diverse maintenance practices and fluctuating budget allocations are noticed on LVRs which significantly impact the overall pavement performance. In this study, the optimal scheduling of maintenance strategies and effectiveness of treatment options are investigated. Pavement maintenance decision making is supported by three approaches: subjective judgment of pavement engineers; historical data on past practice (i.e., historical pavement performance plots); and optimization-based procedures. The three approaches are integrated using a pavement management data of Colorado LVRs to provide guidelines and recommendations for Colorado DOT (CDOT) and other transportation agencies. The accumulated field experience of Colorado DOT’s pavement engineers is highlighted through a regional survey of practice. In addition, the effectiveness of low-cost treatments on the individual pavement distresses is evaluated using historical values of pavement condition indices. It was concluded that some surface treatments and recycling techniques are effective long-term treatments for fatigue, longitudinal, and transverse cracking. However, the effectiveness of these treatments depends mainly on the initial condition index. Then, an optimization analysis is conducted using genetic algorithms to provide cost-effective capital improvement plans statewide and for deteriorated LVRs with marginal pavement conditions. The large-scale optimization analysis is limited on LVRs for statewide maintenance planning. In this study, the developed optimization models have the ability to maximize the overall pavement condition of LVRs network considering an annual budget constraint. They can also minimize the maintenance costs to achieve desired performance targets by the end of the analysis period. It was concluded that most CDOT engineering regions do not have sufficient maintenance budgets to sustain the network-level pavement condition of LVRs. The results from optimization analysis provide more realistic solutions to define the budget needs on LVRs. Moreover, an effective decision-making process is achieved for each Colorado DOT’s engineering region using a machine-learning approach. Multiple treatment alternatives are proposed using artificial neural networks with pattern recognition algorithms. It was found that these approaches provide beneficial guidelines for managing LVRs in Colorado and nationwide. As a result of this study, transportation agencies can determine future budget needs, funding allocations, and treatment policies in order to demonstrate the best possible use of pavement management resources on LVRs.

Available in PDF, EPUB and Kindle. Book excerpt: This textbook covers tools and applications in civil engineering systems. It begins by revising the mathematical and statistical background for the adequate formulation of civil engineering problems. Then it examines a series of topics required to understand infrastructure, facilities and transportation networks, and their planning, maintenance, upgrading and expansion. It covers problem definition, model formulation and decision making systems, including optimization, estimation and prediction. The applications deal with some of the challenges that civil engineers will typically encounter during their professional lives, ranging from municipal planning and infrastructure management to transportation analysis. The treatment of the topics is integral. Tools and examples from real life situations are combined to illustrate the use of methods and principles. Students will learn to understand a system, conceptualize a model, analyse it and make decisions or draw conclusions, just as practising engineers do. A final chapter introduces methods for expanding simple models, adding complexity and incorporating uncertainty. Instructors can chose to cover some of the material from the foundation chapters on mathematics and statistics or directly concentrate on the tools and applications.

Download or read book Developing a Pavement Management System Using Data Fusion of Physical Features written by Tarun Reddy Aleti and published by . This book was released on 2014 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement assessment is still plagued by the expensive and time-consuming distress data collection method. The VOTERS (Versatile Onboard Traffic Embedded Roaming Sensors) project has successfully transformed the way pavement inspections are performed, from mainly visual distresses identification to measurements of physical pavement condition features through the use of various sensing systems mounted on a vehicle. It allows network-wide determination and pavement condition ranking of our vast highway network. This thesis presents how these physical features can substitute for traditional distress assessment methods. Then these substitute features are used as the main inputs to a new kind of Pavement Management System. The first step is to thoroughly understand the current state of practices, especially the PAVER system (MicroPaverTM). Next we focus on using these features, determined from sensor data, in developing a deduct value approach based on nonlinear regression for Pavement Condition Index. A decision tree based algorithm for maintenance, repair and priority programming based optimization algorithms is developed. Using data driven life cycle costs we have shown the benefits of using the VOTERS system. The primary contribution of the thesis is to develop a Pavement Management System that would be automated and that would show the economic benefits for a roadway sector that could potentially use VOTERS sensor and technology.
