This study aims to quantify the health and environmental damages of emissions released by pavement management activities in Ontario. The construction, maintenance, and rehabilitation of pavement results in greenhouse gases and pollutants which have significant impacts on human health and the environment. Traditional lifecycle costing methods used in pavement management systems do not account for the cost of these impacts. Marginal damages which relate atmospheric releases to economic cost can be applied by decision-makers to understand the damages of activities (such as pavement management) but require careful consideration of underlying factors. Marginal damages from various methods across the literature were adjusted for application in this study. The present work quantified environmental costs for the construction and lifecycle maintenance of five pavement design alternatives based on emissions of carbon dioxide and four air pollutants. Concrete roads were found to have the highest environmental costs (equivalent to 77% of agency costs) whereas asphalt roads rehabilitated with Cold-in-Place recycling had the lowest environmental costs due to the reduction in raw materials used. For the asphalt road alternatives, environmental costs were equivalent to 35% of agency costs. Future work will address limitations in data availability and additional design types. These findings provide insight for further integration of externalities in pavement management systems including of noise, user costs, and use phase emissions.

The physical condition of road infrastructure in Canada is not good and roads are in critically condition in many regions. Canadian transportation agencies still require a comprehensive pavement management system (PMS) to guide and recommend the best practices for their appropriate application and communication. The general objective of this research is to extend PMS by incorporating dynamic states of land use, regional economics, travel modeling, and socio-economic development criteria. The specific objectives at regional scale is to integrate regional economy, transport modeling and community development criteria to simulate freight-traffic distribution between Atlantic Provinces of Canada to improve pavement-deterioration modeling and overall province-wide PMS. The specific objective at urban scale is to develop PMS for the road network of Montreal city incorporating simulated traffic and measurement errors free pavement performance curves. Comparison of current practices and proposed PMS based on simulated truck traffic reveals that incorporation of simulated truck traffic into PMS resulted in a more accurate estimation of required levels of funding for maintenance and rehabilitation (M&R). Socio-economic factors of the communities of Atlantic Provinces of Canada are integrated with regional economy and transportation modeling to support multi-criteria based PMS considering that policy makers are not only guided by the engineering characteristics but also by socio-economic benefits of the communities to allocate M&R budget. With and without scenarios of community development criteria into PMS have different implications on M&R budgets. The Backpropagation Neural Network (BPN) method with Generalized Delta Rule (GDR) learning algorithm is applied to develop pavement performance curves for Montreal road network reducing the measurement errors. Finally, a linear programming of PMS is developed for Montreal city incorporating the simulated traffic and pavement performance curves developed by BPN networks. Lifecycle optimization of PMS estimates that CAD 150 million is the minimum annual budget to achieve most of arterial and local roads are at least in good condition (PCI>70) in Montreal city. This research will provide the transportation agencies with an improved decision-making framework capable of delivering a more balanced M&R budget for the achievement of global objectives, such as cost, condition, service, accessibility, and community benefits.

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.

This book gathers the proceedings of an international conference held at Empa (Swiss Federal Laboratories for materials Science and Technology) in Dübendorf, Switzerland, in July 2020. The conference series was established by the International Society of Maintenance and Rehabilitation of Transport Infrastructure (iSMARTi) for promoting and discussing state-of-the-art design, maintenance, rehabilitation and management of pavements. The inaugural conference was held at Mackenzie Presbyterian University in Sao Paulo, Brazil, in 2000. The series has steadily grown over the past 20 years, with installments hosted in various countries all over the world. The respective contributions share the latest insights from research and practice in the maintenance and rehabilitation of pavements, and discuss advanced materials, technologies and solutions for achieving an even more sustainable and environmentally friendly infrastructure.

The authors offer road infrastructure stakeholders with a precise and functional tool that promotes collaboration, common language and comprehension, engagement and interaction among all individuals and institutions involved in sustainable road infrastructure project implementation.
