COURS.

APERÇU

After participating in this course, you will be able to:

• Understand the basic design principles and critical aspects of pavement infrastructure, including the importance of design and constructability reviews.
• Describe cost-effective strategies for maximizing the life-cycle of pavements.
• Identify important issues, inspection tasks, and testing requirements to maximize pavement life.
• Focus on critical items and recognize the consequences of deviations from construction specifications.
• Document the value of high-quality construction inspection and become more observant of potential issues affecting pavement life.

Description
This webinar examines the basic design principles of flexible (asphalt-surfaced) and rigid (concrete-surfaced) pavements to give participants a good understanding of "what matters" to ensure the maximum pavement life possible.

Constructing a pavement is less precise than factory manufacturing, where the input materials and processes are strictly controlled to produce the desired final product. While processes and procedures are in place for quality control and quality assurance, changes and variations in the materials, weather conditions, contractor operations, etc., can significantly impact the pavement's life. Case studies of "cause" and "effect" are presented in a sequence of construction commencing at the subgrade and working towards the pavement surface to illustrate the impact of poor quality construction and inspection on pavement performance. 

Frequently, construction inspectors are not fully aware of the consequences of poor construction practices and are reluctant to "get into an argument" with construction personnel. Pavements typically do not fail catastrophically, and construction defects may take years to manifest themselves in distress and deterioration. The cost to "repair" the defects may be much higher than the original cost of construction, and the repairs themselves may contribute to further pavement distress. By understanding and identifying poor practices and ways of improving them, we can contribute to a sustainable infrastructure system.

Who Should Attend

• Architects and engineers and technicians involved in roadway design, construction and maintenance
• State, provincial and municipal agency personnel involved in the delivery of transportation infrastructure
• Trainers and educators involved in qualifying or certifying construction inspectors
• Contractors interested in advancing roadway construction technology

FORMATEUR

David Hein, P.Eng

David is a consulting Civil Engineer with over 38 years of experience in designing, evaluating and managing transportation infrastructure. He is the past president of the American Society of Civil Engineers Transportation and Development Institute (ASCE T&DI), chair of the Workforce Development and Codes and Standards Councils and chair of 5 engineering standards committees. He is a long-term member of the Transportation Association of Canada (TAC), Past-Chair of the pavements committee and member of the Soils and Materials and Asset Management Committees.

He is also a member of the Workforce Development Council and Chair of the Professional Development Committee. He is also a 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 and is currently the Chair of the Canadian National Committee to the WRA. He 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, 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.
