Abstract Maintaining a functioning road network is a challenge in today’s society due to the financial restrictions faced by all levels of government. A means of determining how to efficiently spend their limited funding must be found. In addition, the concept of sustainable development is rapidly growing in today’s world pressuring municipalities towards operating in a more socially and environmentally friendly manner. Sustainability is broken down into three aspects which are economical, social and environmental. A truly sustainable pavement satisfies its functional requirements while aiding social and economic development and minimizing negative environmental impacts In response to the growing sustainability trend, the City of Markham is committed to incorporating sustainability into their daily operations. This thesis is the result of a research project with the City of Markham which is directed at incorporating sustainable practices into pavement engineering. The objective of this project is to provide a practical framework for incorporating pavement sustainability best practices into the pavement engineering operations at the City of Markham. This practical framework is developed through the completion of four primary objectives. The first main objective involves the completion of a comprehensive literature review that identifies and reviews the state-of-the-art sustainable pavement best practices. This literature review is divided into five pavement related categories which examine: materials, design and construction techniques, maintenance and rehabilitation techniques, sustainability evaluation systems and carbon footprinting. The second objective involves the quantification of the environmental, economic and carbon footprint impacts of the reviewed pavement best practices; this evaluation is conducted using PaLATE. PaLATE is an excel based software developed at the University of California for evaluating the economical and environmental impacts of various pavement technologies. The third objective involves the utilization of GreenPave for evaluating the environmental friendliness of the analysed pavement best practices. The green discounted life cycle cost (GDLCC) is calculated to include the economic aspect of sustainability. The final objective involves the development of project and network level frameworks. These two frameworks are connected which forms the final framework for incorporating sustainability into City of Markham’s pavement engineering operations. Guidelines for the proper utilization of the developed framework are provided. Through the completion of the literature review it is concluded that there is a wide variety of sustainable pavement technologies that range from project design to pavement decommission. PaLATE analysis results indicate that warm mix asphalt and full depth reclamation are the most environmentally friendly construction and rehabilitation techniques, respectively. Including recycled asphalt pavement (RAP) within pavement mix designs reduces both costs and environmental…
