Parking lots, municipal roadways, airports, and major highways all use some form of pavement. Pavements are constructed to provide a safe and durable riding surface for the travelling public. Some may be constructed using a flexible pavement (asphalt) or others rigid pavement (concrete). Which types are appropriate for each application?
What are the functional requirements for rigid versus flexible pavement? How can each be constructed and maintained in a cost effective manner? Pavement construction is very expensive and once the pavement is built, what is important to ensure that we are getting our money’s worth? How do you determine when you need to “fix” something, what is involved, and what are the costs?
- Be able to recognize and use current common pavement design procedures.
- Understand common design and construction features important to the performance of both asphalt and concrete pavements.
- Understand how to assess the condition of existing pavements and to use this information to determine appropriate maintenance and rehabilitation treatments.
- To design and recognize specification and construction activities that can improve the performance of pavements.
- Communicate and promote good road design and construction practices.
The American Association of State Highway and Transportation Officials (AASHTO) 1993 pavement design procedure is covered along with an introduction to the new AASHTO Pavement Design ME mechanistic-empirical method. Design procedures and processes for low volume parking area and roadways are discussed. For existing pavement infrastructure, common procedures are outlined to assist in evaluating pavement condition and to use this information for the cost-effective, long-term management of a pavement network. Common pavement and overall asset management systems ranging from the very simple to very complex will be discussed. The primary design, specification, and construction factors that contribute to the long-term functional and structural performance of pavements ranging from parking lots to municipal roadways, airports, and major highways will also be discussed.
Pavement evaluation and management procedures and sustainability solutions specific to the Canadian environment as outlined in the recently released Transportation Association of Canada Pavement Design and Asset Management Guide are highlighted. The design, evaluation, and management of new pavement systems including permeable pavements are covered. Finally, examples of world-wide innovations in pavement construction and maintenance are presented.
While the course materials are structured, there is ample opportunity to explore any aspects of pavement design, evaluation, and maintenance of interest to the participants. The instructor effectively uses discussion, case studies, and real-world examples to highlight key aspects and interests of the group.
- Pavement network owners and administrators;
- Engineers and technicians involved in the design, evaluation, and management of pavements;
- Provincial, municipal, and local agencies; and
- Airport owners and maintenance staff.

David is a civil engineer with extensive experience in the design, construction, and maintenance of roadway infrastructure. He has 38 years of experience in the design, evaluation, and management of transportation infrastructure. He recently retired from Applied Research Associates, Inc. of Toronto, Canada, where he managed the 90-person Transportation Infrastructure Division in the U.S. and Canada. He is the Past President of the American Society of Civil Engineers Transportation and Development Institute, and Chair of 5 engineering standards committees. He is a long-time member of the Transportation Association of Canada, Past Chair of the Pavements Committee and Past Member of the Transportation Research Board Pavement Management, Pavement Maintenance, and Pavement Preservation Committees.
David has represented Canada on the World Road Association pavements and asset management committees since 2002. He also recently stepped down after 10 years as Executive Director of the Falling Weight Deflectometer User Group. He has been involved in numerous national and international research, technical training, evaluation, and asset management projects for Federal, State, Provincial, and Municipal agencies, and many of the public/private/partnership highway construction projects across Canada and the United States.
