    The Third Symposium on Current and Future Practices for the Testing of Multi-Component Geosynthetic Clay Liners, will be held Wednesday June 27, 2012. Sponsored by ASTM Committee D35 on Geosynthetics, the symposium will be held at the Sheraton San Diego in San Diego, CA, in conjunction with the June standards development meetings of the committee.

    Not long after ASTM Committee D35 on Geosynthetics formed its Subcommittee D35.04 Geosynthetic Clay Liners, the first symposium on Testing Acceptance Criteria for GCLs (STP 1308) was held in January 1996 in Atlanta. The event offered a review of what was then the current knowledge and understanding regarding this geosynthetic product group. In 2003, a second symposium took place in Denver under the theme "Advances in Geosynthetic Clay Liner Technology." This symposium proved to be extremely valuable and was a great success. Both the Subcommittee and the overall engineering community benefited from the symposium's focus on new technical issues, developments, usage and concerns.

    Eight years have passed since that gathering, and with more than two decades of projects and research to draw upon and a new wave of GCL innovation influencing the future direction of the material’s utilization, a third symposium is being planned for June 2012.

    A major motivator for this new symposium is the advent of "multi-component GCLs." These materials can be defined as a "GCL with an attached film, coating, or membrane that decreases the hydraulic conductivity or protects the clay core or both." Either a thin plastic barrier is attached to one geotextile component of the GCL or a geotextile component is coated with a polyolefin polymer. In both cases, the added barrier extends the GCL's range of use to a number of site conditions that were previously considered prohibitive (e.g., presence of roots, greater chemical threat, protection against desiccation, etc.). It is now the task of ASTM D35's Subcommittee D35.04 to identify the proper tests for these newer multi-component GCLs, either by adopting/modifying existing test methods or developing new procedures to help designers, owners, operators, regulators, manufacturers and other stakeholders test these materials.

    Topics of the symposium include:

    • Mechanical testing
    • Peel and Shear Behavior
    • Hydraulic Testing
    • Durability of multi-component
    • Field Performance
    • Research Studies

    The language of the symposium will be English.
