Federal Aid and Non Federal Aid roads are the most important assets for every local government. Collecting data, analyzing and proposing a practical and cost-effective work plan has been the goal of local agencies. Implementing pavement management process can help local agencies to make the best decision regarding road investments. In this study, pavement management is comprised of two main parts. At the network level, the macroscopic model is adopted where each decision variables represents a specific proportion of the asset network. For each decision variable, future condition prediction models are developed. An annual budget scenario can be analyzed with the flexibility to vary the treatment unit costs, allowable treatments, treatment average life and the span of the analysis period. At the project level, the microscopic model is implemented to generate a detailed work plan based on the results from network level part. Also culverts are of the crucial parts of transportation assets and their failures can jeopardize the ecosystem and result in accidents. Inspecting and developing a management system can help agencies to better understand the current and future condition. In this thesis for a given budget level, the corresponding performance of the asset network is determined using the linear programming optimization with the objective of average network condition maximization. The optimization model consists of an asset deterioration model. The deterioration rates are predicted based on the historical condition data using the Markov model. Then, the results from linear programming used to provide users with a detailed work plan.

Comprehensive and practical, Pavement Asset Management provides an essential resource for educators, students and those in public agencies and consultancies who are directly responsible for managing road and airport pavements. The book is comprehensive in the integration of activities that go into having safe and cost-effective pavements using the best technologies and management processes available. This is accomplished in seven major parts, and 42 component chapters, ranging from the evolution of pavement management to date requirements to determining needs and priority programming of rehabilitation and maintenance, followed by structural design and economic analysis, implementation of pavement management systems, basic features of working systems and finally by a part on looking ahead. The most current methodologies and practical applications of managing pavements are described in this one-of-a-kind book. Real world up-to-date examples are provided, as well as an extensive list of references for each part.

Roads are one of the most valuable infrastructure assets within a community. Proper maintenance of the roadway network can promote the prosperity of a community. In recent times maintenance has become much more difficult with the price of asphalt increasing drastically and city budgets contracting due to the economic downturn. With these conditions, the proper management of an agency0́9s street network is necessary. The use of pavement management systems provides the help needed in the preservation of the street network. The use of pavement management systems provides significant benefits such as identification of the most cost-effective pavement treatment actions and accurate predictions of pavement deterioration. The research objectives are to examine and explain how local agencies benefit by using an adequate pavement management system and to develop a pavement prediction model appropriate for use in local agencies. This report provides a comparison of three different Pavement Management Systems: TAMS (Transportation Asset Management System), a Pavement Management System (PMS) developed by Utah the LTAP (Local Technical Assistance Program), a PMS developed by the Alabama DOT for use in cities and counties, and Micro PAVER a widely used commercial PMS. Their unique characteristics and individual strength and weaknesses are discussed so that potential users of PMS can better decide what fits best their agencies' needs. Then TAMS is explained in detail as an example of pavement management system and a case study of its application in Tooele city, Utah. Then an economic analysis of no pavement management, a partial pavement management system, and a full pavement management system is provided. The full Pavement Management System showed a savings of about

Multiple objectives are often used by agencies trying to manage pavement networks. Often alternative investment strategies can accomplish the agencies' target objectives. If the goal is to achieve the target objectives at the minimum cost, an approach is needed to assist agencies in identifying investment strategies capable of meeting the targets while minimizing costs. The approach used by the agency should not be limited to an analytical method to mathematically solve the funding allocation problem. Finding mechanisms to ensure the sustainability and efficiency of the investment strategy over time is a great challenge that needs to be addressed by the approach. The challenge is even greater for local agencies where resources are usually limited. This research develops a multi-objective strategic management approach oriented to improving decisions for pavement management practices in local agencies. In this approach, target objectives are tied to key pavement network parameters in the management process. A methodology to identify the best combination of projects to meet target objectives at the minimum cost while maximizing treatment effectiveness is provided as a result of the research. Concepts from the pavement management program (PMP) of the Metropolitan Transportation Commission (MTC) of the San Francisco Bay Area were used as a basis for developing the methodology. Four pavement network parameters are considered for setting the target objectives over the agency's planning horizon: the average network pavement condition index (PCI), average network remaining life, percent of the pavement network in good condition, and percent of the pavement network in poor and very poor condition. Results from a case study show that funding allocation methods influence the allocation of preservation and rehabilitation funds among pavement network groups, affecting budget estimates and future condition of the pavement network. It is also concluded that the use of mechanisms that facilitate data integration and the flow of knowledge across management levels can contribute to making better informed decisions. Hence, the adoption of the multi-objective strategic pavement management approach developed in this dissertation should lead to identifying more efficient investment strategies for achieving the pavement network state desired by a local agency at a minimum cost.

Throughout the course of time and due to budget constrains agencies have changed their emphasis from construction of new roads to maintenance and rehabilitation of existing pavement structures. To achieve so, proper evaluation of the pavement's condition has been the principal source of information for effective road network management of state, city, and local transportation agencies. The necessity of obtaining the most benefit from limited funding led to the desire of Carson City and Douglas County's Public Works offices to implement a Pavement Management System for their networks. To achieve so, the Paver Software was selected as the common data management tool. Thorough data analysis of the pavement condition and work history data is necessary to obtain accurate performance prediction models. Lack of data was compensated with sewer line construction data and engineering judgment along with a three tier cleaning process. The current budget of both agencies was shown to be significantly lower than the necessary budget to maintain or improve the overall pavement network condition to an acceptable level. The reports generated serve the agencies to prioritize their spending through cost effective treatments, defend themselves against public criticism, and for requesting additional funding. Based on the findings from this study, it was recommended for local agencies to develop pavement management systems to apply the most cost effective treatments and obtain the most out of their limited budgets. A plan was provided on how to maintain and update the developed pavement management system.

Pavement Management Systems are decision-making frameworks set up by local agencies concerned with management of transportation infrastructure to make efficient allocation of available resources to maintain the infrastructure in a predetermined state. Although large transportation agencies have been able to set up such frameworks, small local agencies find it tough to install such systems because of lack of relevant data and experienced personnel to implement such complicated systems. The objective of the research was to advance the Asset Management Program developed by the University of Missouri-Columbia by incorporating analytical tools that would help local agencies in conducting optimization for the pavement network with the minimum initial amount of data and resources. Two types of optimization problems were solved; (i) Maximize the overall condition of the road network under budgetary constraints; and (ii) Minimize the budget required to maintain the overall pavement condition above a particular level of service under policy constraints. The formulation was solved in C programming language as well as in Microsoft Excel format while taking care that both the methods use the same input file and format to ensure robustness of the formulation.
