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
The Romans built round 90,000 kms of roadways within their empire. They consisted of four layers of rubble, coarse stone subbase, finer stone base and lime grouted stone slabs as a surface. The pavement sections were between 1 and 2.5 m in thickness to suite local subgrade conditions and materials. It wasn’t until the mid-1800s that Thomas Telford and John Macadam introduced new principles and materials to road construction. In the early 1900s, "bitulithic" and "cement concrete" materials were used to surface pavements. Throughout the next 100 years, there have been many developments in the design and construction of both flexible and rigid pavements.
This webinar provides a history of pavement design in the United States. It covers the agencies and engineers who advanced the science of road building. While there have been many advances over the past 100 years, poor pavement performance is not uncommon even in this day and time.

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]
