Some of the key design elements for asphalt pavement design and construction include:
- Subgrade preparation
- Thickness
- Instability
- Cracking
- Segregation
- Asphalt stripping
- Mix problems
- Drainage
- Maintenance procedures
Pavement evaluation and management procedures and sustainability solutions specific to the Canadian environment as outlined in the Transportation Association of Canada Pavement Design and Asset Management Guide will be highlighted. The design, evaluation, and management of new pavement systems, including permeable pavements, will also be covered.
Once a pavement is designed, it must be properly constructed. The process begins with the preparation of the subgrade/foundation and is followed by placement of the base/subbase and flexible pavement surface which may be granular aggregates, chips seals or asphalt concrete. Key components of each pavement surface are discussed along with best practices for the material components and their, manufacture, transportation, and placement. Best practices for the maintenance of pavements and examples of both good and poor construction and maintenance will also be provided during the course.
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.
- Be able to recognize and use current common pavement design procedures.
- Understand common design and construction features important to the performance of municipal roadway, trail, and sidewalk infrastructure.
- 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.
- To understand the production and placement of asphalt concrete.
- Communicate and promote good road design and construction practices.
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 (ASCE T&DI), and chair of 5 engineering standards committees.
He is a long-time member of the Transportation Association of Canada (TAC), Past-Chair of the pavements committee and past member of the Transportation Research Board pavement management, pavement maintenance, and pavement preservation committees. He has represented Canada on the World Road Association (WRA) 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.
