ASCE webinars are great for us. We are in a remote location and it is difficult to get quality training for our staff without much expense." Anonymous Attendee
INSTRUCTOR: David K. Hein, P.Eng.
Purpose and Background
This webinar provides an introduction to the design of flexible and rigid pavements. The American Association of State Highway and Transportation Officials (AASHTO) 1993 pavement design procedure is covered along with an introduction to the new AASHTOWare Pavement ME Design mechanistic-empirical method. 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. 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.
Primary Discussion Topics/Webinar Outline
This webinar focuses on design and construction features that may impact the performance of our 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
- Maintenance procedures
Some of the key design elements for asphalt pavement design and construction include:
- Subgrade preparation
- Thickness
- Surface Instability
- Cracking
- Segregation
- Asphalt stripping
- Mix problems
- Drainage
- Maintenance procedures
Learning Outcomes
- Be able to recognize and use current common pavement design procedures
- Understand common design and construction features important to the performance of both asphalt and concrete pavements
- To design and recognize specification and construction activities that can improve the performance of pavements
- Communicate and promote good road design and construction practices
Webinar 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
Intended Audience
- Engineers involved in the design, evaluation and management of pavements
- State/Provincial DOT and municipal agencies
