None. Suitable for all levels of interest both technical and non-technical.
This course discusses pavement design, specification, subgrade preparation, base/subbase, and surface types and function, construction details, and long-term functional and structural performance considerations to ensure a long-life and effective product. It provides details on maintenance and rehabilitation procedures, how to evaluate both old and new, and innovative pavement treatments using life-cycle cost analysis. Through a series of case studies, positive and negative design features and construction conditions are presented to give the participant a good understanding of what we can do better to ensure the cost effective use of transportation investments.
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. With the recent 2013 flooding in Calgary and Toronto and municipal interest in green infrastructure solutions for stormwater quantity and quality management, interest in the use of permeable pavements has been rapidly increasing. Cities such as Vancouver, Calgary, Toronto, and numerous private sector developers have been designing and building permeable pavements. Key permeable pavement design, construction, and maintenance features are presented.
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 are 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 are discussed. The design portion of this course focuses on features that may impact the performance of asphalt and concrete pavement infrastructure.
Some of the key design elements for concrete pavement design and construction include:
- Subgrade preparation
- Dowel bar: alignment; insertion; quality
- Dowel and tie bar placement
- Joint detailing
- Proper detailing around utility covers
- Finishing
- Joint and crack sealing
- Deleterious materials
- General construction site cleanliness
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 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.
