The Workshop on Geosynthetic Materials Durability: Field and Laboratory Experiences, will be held January 29, 2010. Sponsored by ASTM Committee D35 on Geosynthetics and the Geosynthetic Research Institute (GRI), the workshop will be held at the Grand Hyatt San Antonio in San Antonio, Texas, in conjunction with the January 27-29 standards development meetings of Committee D35. ASTM Committee D35 and the Geosynthetic Research Institute are pleased to invite you to submit abstracts in support of this important workshop on geosynthetic materials durability. The workshop will focus on all types of geosynthetic materials durability in both covered and exposed applications, and will be organized in four parts. 1). Long-term field experiences under various environmental conditions; i.e., exposed versus covered, hot versus cold, wet versus dry, stressed versus nonstressed. 2). Accelerated weathering studies. All types of geosynthetics which have been evaluated from the perspective of durability are encouraged, particularly if corroborated with field experiences. Note that the workshop is on polymer durability and not on long-term creep, creep rupture, or installation damage. 3). Polymers and additive packages that constitute the final geosynthetic material's formulation. This critical aspect of durability is rarely discussed in open forum and the workshop organizers feel that (after 40-years of geosynthetics use) the time has come. Examples of premier as well as unsuccessful formulations are greatly encouraged. The fourth part of the workshop will consist of a panel of experts who will summarize the workshop and project research durability needs into the future. Discussions on lifetime prediction methods and projected values will also be included. Request for Abstracts: Several more titles and abstracts for this Workshop are still being solicited and are due by December 31, 2009. Based upon their appropriateness and acceptance, the formal final program will be developed. Titles and extended summaries (2 to 5 pages) will then be required by January 5, 2010. The final abstracts will form the information booklet which will be distributed to all participants at the Workshop. All oral presentations will be on Power Point with a time allocation of 15 to 25 minutes, depending on the response to this solicitation. Information Titles and initial abstracts must be sent to both of the workshop co-chairs, Sam Allen and George Koerner:
