This webinar was co-sponsored by ASCE's Transportation and Development Institute (T&DI) and ASCE Continuing Education

Instructor:  David K. Hein, P.Eng.

Course Length: 1 Hour

This webinar is part of a 3-part series on Roadway Construction

Purpose and Background

The American Society of Civil Engineers (ASCE) issues an annual report on the state of the transportation infrastructure in the United States. Since 1998, the grades have been near failing, averaging only Ds, due to delayed maintenance and underinvestment across most categories. One of the most effective ways of improving the condition of our transportation infrastructure is to make it last longer.

This webinar examines the basic design principals of flexible (asphalt surfaced) and rigid (concrete surfaced) pavements to give participants a good understand of what matters to ensure the maximum pavement life possible. Constructing a pavement is not as precise as factory manufacturing, where the input materials and processes are strictly controlled to result in the desired final product. While processes and procedures are in place for both quality control and quality assurance, changes and variations in the materials, weather conditions, contractor operations, etc. can have a significant impact on the life of the pavement. 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.

This webinar is part of a 3-part series of webinar on Roadway Construction, Inspection and Maintenance Techniques to Minimize Life-Cycle Costs. The complete series of webinars includes:

• Part 1: Roadway Construction Inspection Techniques: Easy Methods to Improve Pavement Performance
• Part 2: Roadway Construction Quality Control and Inspection Techniques for Concrete Surfaced Pavements
• Part 3: Roadway Construction Quality Control and Inspection Techniques for Asphalt Surfaced Pavements

This first webinar in the series “Roadway Construction Inspection Techniques – Easy Methods to Improve Pavement Performance” provides an overview of the basic design principles for high quality pavement construction, maintenance and rehabilitation.

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]
