Note:
Many agencies across Canada have had a strong focus on our transportation infrastructure debt. Our focus has change from the construction of new infrastructure to the maintenance and rehabilitation of our existing roadways and highways. We have a substantial investment that must be preserved and maintained. This course provides an overview of the most popular design methods for roadway pavements and then focuses on methods and procedures to evaluate pavement condition to determine how we can cost-effectively extend their service life. Case studies show examples of pavement condition, why it is in the condition and how best to cost-effectively treat defects to maximize the life of the asset. Pavement preservation and life-cycle cost procedures are discussed to assist asset managers in conveying the importance of timely maintenance and rehabilitation actions.

Course Objectives
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), others rigid pavement (concrete). Which types are appropriate for each application?  What are the functional requirements for rigid vs. 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 I determine when I need to “fix” something?  What is involved?  What are the costs? 

Course Benefits              
  • Understand key components and factors necessary for the cost effective design of flexible and rigid pavements.
  • Be able to identify design and construction features that may negatively impact the performance of pavements.
  • Assist in developing specifications to ensure the performance of pavements. 
Full Description
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. The course also 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. 

Municipal interest in green infrastructure solutions for stormwater quantity and quality management, 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 our 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 and 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. 

Unique Features of 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. 

Target Audience:
  • Pavement network owners and administrators
  • Engineers and technicians involved in the design, evaluation and management of pavements
  • Provincial, municipal and local agencies
  • Airport owners and maintenance staff
