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
Purpose and Background
This webinar offers a foundational overview of roadway construction inspection techniques aimed at minimizing lifecycle costs and ensuring long-term pavement performance. The presenter emphasizes the importance of building roadways correctly from the start as a means of achieving sustainability, rather than relying solely on alternative materials. The session explores the design and construction elements essential for durable flexible and rigid pavements, including subgrade preparation, proper drainage, material selection, and compaction. Attendees gain insights into how environmental factors, material variability, and inadequate inspection practices can contribute to premature failure. The presentation also highlights common inspection challenges, the role of documentation, and the importance of experienced inspectors. Real-world examples and best practices are shared to underline the consequences of poor construction and how to avoid them.
Benefits and Learning Outcomes
Upon completion of this course, you will be able to:
- Describe the essential components and construction techniques required for building long-lasting and cost-effective roadway pavements.
- Identify the key causes of pavement deterioration, including subgrade variability, environmental impacts, and construction deficiencies.
- Explain the differences between flexible, semi-rigid, and rigid pavement types and their appropriate applications in various traffic and environmental conditions.
- Discuss best practices in construction inspection, including the importance of proper documentation, quality control testing, and communication among project stakeholders.
- List common construction defects and how proper planning, joint layout, and materials handling can prevent premature pavement failures.

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]
