Virtual Workshop Brief

Road infrastructure is critical to the economic viability of the country. It provides access for the distribution and consumption of goods and services, mobility and access to health care, sports and exercise facilities, entertainment and tourism. We have developed our modern roadway infrastructure over the past 100 years or so. The network has had to adapt to changing vehicle loads and configurations, climate change and environmental deterioration and it will continue to adapt in the future. Pavement design is continually changing to meet these new challenges. The purpose of this workshop will be to provide hands on experience in the use of common pavement design procedures. This includes layer equivalency, deflection based, and American Association of State Highway and Transportation Officials (AASHTO) 1993/1998 methods. Participants will also be introduced to new mechanistic-empirical methods which being adopted by State and Provincial Highway agencies across North America and is gaining use by Municipal governments. Participants will be provided with basic information required to effectively design a high traffic volume municipal roadway, a residential roadway and a parking lot. Access will be provided to a web-based application to carry out the designs. The participants will be asked to submit example designs by the end of the first day with the results discussed in an open forum on the second day.

Primary Topics of Discussion

The primary discussion topics include:

• Methods and history of pavement design
• Key design inputs:
• Subgrade support
• Bases and subbases
• Traffic
• Reliability
• Mechanistic-empirical design
• Traffic characterization
• Subgrade and pavement materials characterization
• Impact of the environment
• Failure mechanisms
• New and emerging technology and their impact on pavement performance

Benefits and Learning Objectives

Upon completion of this course, you will be able to:

• Explain the key pavement design inputs and the impact on pavement performance
• Compare results from different design procedures
• Assess the sensitivity of various inputs to pavement design
• Explain how to access and use the PaveXpress on-line pavement design tool
• Recognize the importance of long-lasting pavement infrastructure
• Utilize common available tools to design cost-effective pavements
• Identify the contribution of various pavement layers to performance

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed through case study analysis exercises and class discussions following the presentation of each major topic. A short post-assessment (true-false, multiple choice and fill in the blank questions) will also be administered.

Who Should Attend

• Owners and managers of pavement infrastructure
• Engineers involved in roadway design and construction
• Geotechnical specialists dealing with transportation infrastructure
• Contractors involved in the construction of roadways
• Suppliers of construction materials for pavements

Outline

Interactions: The workshop will be delivered in an adult-learning format that is centered around the concept of learning by interaction. To this end, each topic in Day 1 and 2 will include poll questions to foster and facilitate interactions. The attendees will be encouraged to share their experiences. The homework assignment will require the participants to complete pavement designs for specific scenarios that will be shared on Day 2 of the workshop. In addition, participants will be asked to take photographs of road distresses from their neighborhood to be discussed on Day 2 of the workshop.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
