Geosynthetics October/November 2020 - Geosynthetics Conf. Brochure 4

Panel Discussions
Panel discussions are a source of lively debate during Geosynthetics
Conference. Audience participation is strongly encouraged.
At What Frequency Should We Take Seam Destructive Samples?
Moderator: Glen Toepfer, CQA Solutions, LTD

Over the past decade, the debate about destructive testing frequencies has heated up as the
standard frequency of 1 sample per 500 lineal feet of welding has been criticized and challenged.
There have been numerous alternatives suggested, yet the most common specification found on
containment projects remains the 1/500.
What factors should be considered in determining the appropriate sampling frequency?
Materials? Weld type? Experience? Use of smart technology welding equipment? Non-destructive
seam testing failures? Should the frequency be changed? Should the change be universal for the
industry or determined on a project-by-project basis?
A panel composed of key members representing a cross-section of the containment system
industry will try to answer these questions and more in what is sure to be a lively discussion!

Geosynthetic Specifications:
The Pros and Cons of Existing Geosynthetic Specifications
Moderator: L David Suits, LDS Geosynthetics Consulting Services

Panel members will review critical geosynthetics specifications in the areas of landfill systems,
erosion control systems, pavement systems, earth structure systems, and drainage systems,
focusing on the current pros and cons of each as well as potential future developments. Audience
participation is strongly encouraged as potential improvements to the specifications are explored.

Measuring the Performance of Geosynthetic Roads-Bench Top to Full-Scale
Testing and Monitoring Method
Moderator: Eli Cuelho, TRI Environmental and Jeb Tingle, USACE

There are several test methods and equipment styles currently used to measure the large-scale or
full-scale performance of roadways that utilize geosynthetics as reinforcement and/or stabilization.
Designers ultimately desire to have performance data that are accurate and reflect the true benefit
of using geosynthetics in roads so they can confidently use this information in design; however,
many research projects often present confounding results or are inconclusive due to the lack of
standardization. Test methods are currently being developed that would benefit from the input of a
broader audience to improve the likelihood of successful adoption and implementation.

The Permanent Road Foundation Experience
Moderator: Mark Marienfeld, Propex Consultant

Arguably the largest asset of most transportation agencies is the unbound aggregate used as
road support. This huge asset does not receive the attention it deserves and is largely placed and
forgotten. Inadequate forensic research is conducted to prove to agencies that the degradation of
aggregate layers is the root cause for most premature road failures, and unnecessary maintenance
and repair. Members of this panel will; explain the problem of base aggregate contamination,
propose a simple geosynthetic solution, explain a Permanent Road Foundation, discuss stone
requirements, verify DOT successes, explain FHWA oversight responsibility, explain the lack of
transportation asset management attention, and identify research needs. Interaction with the
audience will be encouraged. Goal is to bring more attention to the unnecessary loss of aggregate
while verifying that a Permanent Road Foundation; reduces construction and maintenance cost,
reduces road downtime and traffic congestion with the associated poor traffic safety statistics,
and conserves resources and lowers our carbon footprint.

Women in Geosynthetics Round Table Discussion
Moderator: Jordan Wiechmann, Plastatech Engineering, Ltd and Jen Miller Fabricated Geomembrane Institute

The Fabricated Geomembrane Institute at the University of Illinois has created a group titled,
"Women in Geosythetics (WIG)" in order to promote the advancement of women in the
geosynthetics industry through education, networking and mentoring opportunities. Audience
participation is the focus of this highly interactive discussion
The discussion will include, but is not limited to the following points of interest:
*	 How can we recruit MORE women into the Geosynthetic Industry?
*	 How can we create more opportunities in the industry for women?
*	 What types of educational opportunities are out there to educate women
throughout the industry?
*	 Mentorship opportunities
