Building a Better Road—Designing & Constructing Pavements for Superior Long-term Performance

COURSE DESCRIPTION

Lasting infrastructure begins with good design and construction. Join David Hein, P.Eng. to explore the design, specification, and construction elements that impact the performance of asphalt and concrete pavements, as well as the primary factors that contribute to the long-term functional and structural performance of pavements ranging from parking lots to municipal roadways, airports, and major highways.

Through a series of photographs, we’ll explore the positive and negative features to gain a comprehensive understanding of what we can do better to ensure the cost-effective use of transportation investments.

Discussion will cover elements that may cause problems for concrete pavement construction, including:

  1. Subgrade preparation
  2.  Dowel bar alignment
  3.  Dowel and tie bar placement
  4.  Dowel bar insertion
  5.  Dowel bar quality
  6.  Joint detailing
  7.  Proper detailing around utility covers
  8.  Finishing
  9.  Joint and crack sealing
  10.  Deleterious materials in the concrete mix
  11.  General construction site cleanliness

Discussion will also cover elements that may cause problems for asphalt pavement construction, including:

  1. Subgrade preparation
  2.  Thickness
  3.  Instability
  4.  Cracking
  5.  Segregation
  6.  Asphalt stripping
  7.  Mix problems
  8.  Drainage
  9.  Maintenance procedures
