“Composite Drainage Nets – Design and Testing”
Presented by:
Bob Mackey, P.E., BCEE
S2L, Incorporated
Maitland, Florida, USA
DATE: Wednesday July 9, 2014, 1:00 – 2:00 pm EST
ABSTRACT: The development of composite drainage nets (CDNs) (a.k.a. “geocomposites”) has advanced from the initial biaxial nets to tri-axial nets to the current composite drainage products of various geosynthetic materials and structures. The use of CDNs requires a fundamental knowledge of the CDN components and the specifications for those materials.
This North American Geosynthetics Society webinar will address the various design, testing and installation issues one must consider with composite drainage nets. Issues include:

“Recent insights on the performance of GCLs in bottom liners and covers”
Presented by:
R. Kerry Rowe
GeoEngineering Centre at Queen’s-RMC
Queen’s University, Kingston, Canada
DATE: Wednesday March 19, 2014, 1-2 pm EST
ABSTRACT: The available evidence suggests that both geosynthetic clay liners (GCLs) and composite liners with a geomembrane (GMB) over a clay liner have performed extremely well at controlling leakage in field applications for a couple of decades. However there have also been some problems reported and recent research has allowed us to have a much better understanding of the key design and construction factors affecting good and poor performance. This lecture examines some of these issues affecting GCL performance such as the water retention curve of GCLs, subgrade grain size and initial water content, GCL water content and normal stress on the GCL, the effect of daily thermal cycles on hydration, GCL panel shrinkage, and cation exchange. Factors affecting composite liner performance examined include the potential for desiccation of the clay liner under a sustained thermal gradient, GMB/GCL interface transmissivity, wrinkles in the GMB when the ballast layer is placed over the composite liner, and the potential interaction between wrinkles and GCL panel overlaps. Recent insights regarding leakage through composite liners are discussed. Although a number of potential issues with liner performance are discussed, it is concluded that all can be addressed by appropriate design, material selection, construction, and operation.
ABOUT THE SPEAKER: Professor Rowe holds the Canada Research Chair in Geotechnical and Geoenvironmental Engineering at Queen’s University. He is an author of 300 journal papers, 3 books, 18 book chapters, and 290 full conference papers. He has presented many prestigious lectures including the Giroud Lecture (2002), Rankine Lecture (2005), and Casagrande Lecture (2011). He is a fellow of the Royal Society of Canada, the Canadian Academy of Engineering, the Royal Academy of Engineering and The Royal Society.

L. David Suits
L. David Suits, executive director of the North American Geosynthetic Society, Albany, N.Y., has received the A. Ivan Johnson Outstanding Achievement Award from ASTM International Committee D18 on Soil and Rock. This award is presented to a member whose efforts have produced a particular outstanding result orsignificant contribution to the work of the committee.
A dedicated ASTM International member for more than 35 years, Suits works on several subcommittees within Committees D18 and D35 on Geosynthetics. He is a founding member and past chairman of D35 and currently leads Subcommittee D35.03 on Permeability and Filtration as well as the D18 group on the Geotechnical Testing Journal, where he serves as a co-editor. Suits is also a member of Committee D04 on Road and Paving Materials and has served terms on the ASTM Standing Committees on Publications and Technical Committee Operations. He has received several standards development and service awards from D18 and D35, and was honored with the ASTM International Award of Merit and title of Fellow, ASTM’s highest organizational recognition for individual contributions to standards activities, in 1986.
Suits specializes in soils and geosynthetics testing. He was employed by the New York State Department of Transportation for 37 years, where he held various positions of increasing responsibility, including assistant soils engineer and soil mechanics laboratory supervisor, where he over saw the performance of all foundation design testing done in conjunction with the department’s $1 billion design and construction program. In 2005, he retired from NYSDOT and became executive and managing director of the North American Geosynthetics Society, a group that provides leadership for the advancement of education and research ingeosynthetics.
Outside ASTM International, Suits is a member of the American Society of Civil Engineers Geo-Institute and the International Geosynthetics Society.

Prof. John S. McCartney – 2013 ASTM Award Winner
John S. McCartney, Ph.D., an assistant professor at the University of Colorado, Boulder, Colo., has been announced as the recipient of the 2013 President’s Leadership Award from ASTM International. The President’s Leadership Award recognizes individuals early in their ASTM career who have significantly advanced the Society’s mission through extraordinary accomplishment, example and vision, and is presented to two ASTM members annually. This year’s other recipient is William C. Griese, standards development and green initiative manager at the Tile Council of North America (TCNA) in Anderson, S.C. McCartney has served on Committees D18 on Soil and Rock and D35 on Geosynthetics.
As well we are proud to have John as a long standing Member of NAGS and as the Co-Chair of the Student Activities for GeoAmericas 2016 – the 3rd Pan-American Regional Conference on Geosynthetics. Congratulations and thanks to John from NAGS!
The year 2012 has been an active year for NAGS. We have co-hosted, with GMA, a series of regional short courses. We anticipate at least four of these sessions to be held during 2013.
We have participated both with financial support, and attendance at, the Lobby Days organized through GMA and its lobbyists. There have been very positive results from that activity with a congressional mandated report by the Government Accounting Office was released in November on the benefits of using geosynthetics, as well as language in the transportation bill encouraging the use of innovative materials such as geosynthetics in the design and construction of transportation facilities. A copy of the report is available HERE
We worked with IFAI and GMA in conjunction with the Geosynthetics 2013 Conference to be held in Long Beach, CA. April 1-4, 2013. The conference is co-located with the FHWA Southwest Geotechnical Engineers, and the GRI 25 Conferences. We have agreed on the arrangements to participate in the Canadian Geotechnical Society Annual Conference to be held in Montreal in late September 2013.
In conjunction with the Geosynthetics 2013 NAGS will hold its biennial meeting where the new Board of Directors, including the new President, President-elect, and Board members will be introduced.
While we have over 200 members now, growth in membership will allow us to pursue other activities that promote the use geosynthetics. In that regard we would like to ask your help. We encourage each member to recruit at least one new member. As an incentive to do this we are offering, compliments of IFAI/GMA, a one year subscription to “Geosynthetics” for any US or Canadian member renewing for 2013 who recruits at least one new member.
A new website that incorporates many new features, including the ability to share news of members and the industry, a calendar of upcoming events, links to various other sites including the IGS site and a LinkedIn Group, pictures, and more, will be available during the first quarter of 2013. Watch for the announcement.
Should there be any questions regarding anything about NAGS, please don’t hesitate to contact me. We are looking forward to another successful year in 2013, and it will be with your support that this will be possible.
We are the North American Chapter of the International Geosynthetics Society (IGS), serving and representing infrastructure and sustainability professionals in Canada and the United States.
