On-Demand: A Trilogy of Giroud and Han Reinforcement Presentations

Geo-U Reinforcement PresentationsThe geotechnical engineering professional development website Geo-U (www.geo-u.com) has added two presentations from Drs. JP Giroud and Jie Han to its roster of high-quality, on-demand education. A third presentation will be added shortly to complete a trilogy of reinforcement offerings, each of which is worth 1.5 PDHs following successful completion of post-presentation tests. The new presentations, which are accessible 24 hours per day from anywhere in the world, are “Design of Geosynthetic-Reinforced Unpaved Roads” (presented by both Giroud and Han) and “Mechanisms of Geosynthetic Reinforcement in Roads.”

The forthcoming third presentation in the series will focus on reinforcement of paved roads.

Giroud and Han are both well-known in the field, but their names became linked in road reinforcement designs a decade ago when they published what is commonly referred to as the Giroud-Han Design Method.

About This Geo-U Reinforcement Trilogy


Design of Geosynthetic-Reinforced Unpaved Roads” – Drs. JP Giroud and Jie Han

This presentation, worth 1.5 PDH with successful completion of a post-presentation test, offers a nice update on unpaved road reinforcement. It delivers content not onlyfor geogrid designs but geocells in unpaved roads.

The layout of the presentation:

  • Introduction
  • Historical Development of Design Methods
  • Development of Giroud and Han Method
  • Calibration for Geogrid-reinforced Unpaved Roads
  • Calibration for Geocell-reinforced Unpaved Roads
  • Design Example
  • Discussion and Guidance for Proper Use
  • Concluding Remarks

NOTE: Dr. Giroud recommends that to get the greatest impact from this presentation one should first have a strong understanding of the mechanisms of reinforcement in roads. Hence, a complementary course is offered for those who want to refresh their understanding prior to viewing this presentation. The description of the mechanisms of reinforcement course follows.


Mechanisms of Geosynthetic Reinforcement in Roads” – Dr. JP Giroud

A complementary course, and for many an introductory course, to “Design of Geosynthetic-Reinforced Unpaved Roads,” this course is led solely by Dr. JP Giroud. It also serves as an introductory course to the Dr. Han-led presentation on “Design of Geosynthetic-Reinforced Paved Roads,” which will be added to Geo-U.com shortly.

The “Mechanisms” course is worth 1.5 PDH, following successful completion of the post-presentation test.


“Design of Geosynthetic-Reinforced Paved Roads” – Dr. Jie Han

The presentation is forthcoming.
