24 November 2009 – The ASTM Committee D35 on Geosynthetics meeting in San Antonio, 27-29 January 2010, will feature important new events which we’ve highlighted below:
Geocell Standardization Exploratory Meeting
Wednesday, January 27, 10:30 am – 12:00 noon
Geocell products been used successfully for a variety of applications. However, many regulators, specifiers and users have related significant market variability with regard to product characterization, market specifications and product quality. In this important inaugural meeting, all interested individuals are invited to attend and contribute to this discussion of potential D35 standardization efforts. Two major producers will be on hand to present case histories, answer product questions and discuss needed standardizations.
Shear Strength Test Result Interpretation
Wednesday, January 27, 3:00 – 4:00 pm
In response to a wealth of significantly different shear strength specifications and result interpretation practices, a new effort has been initiated to draft a Standard dealing with interpretation of interface friction test results. Contributors to this important effort are sensitive to those that do not desire a mandatory and authoritative standard ignoring or negating site-specific engineering judgment. Interested parties are invited to attend and provide input into this developing Standard Guide.
Subgrade Reinforcement
Thursday, January 28, 8:00 – 9:00 am
This ongoing standardization effort meets again to review cyclic tension testing and the recently completed ASTM D 7499, Geosynthetic-soil resilient interface shear stiffness.
Workshop on Geosynthetic Material Durability: Field and Laboratory Experiences
Friday, January 29, 8:00 am – 5:00 pm
This workshop will focus on durability issues with all types of geosynthetic materials and applications. Presentation titles include: Laboratory Weathering of Various Types of Geomembranes; Predicting UV Durability of Exposed Geosynthetics with QUV Weatherometer Data; Service Lifetime Assessments of Hypalon, HDPE, fPP, PVC, and VLDPE Geomembranes; Parametric Transitions in the Determination of Exposed HDPE Geomembrane End of Life; Case Histories of Exposed HDPE; Case History of HDPE Geomembrane Durability; PVC Durability: 15 Year Exposed Case History; the Flaking Failure of a Water Reservoir’s Geomembrane Floating Cover and Liner; Engineering Properties of Geosynthetics Exhumed from Final Covers for Waste Containment; Nanocomposite Resin and Their Effects on Physical and Mechanical Properties of Geosynthetics; Long-Term Field Study of Nonwoven Geotextiles in Earthern Flood Control Dams; the Long Term Durability of Polyester Based Geosynthetics after 20-30 Years of Field Service; Durability of GCL; GCL Seam Testing Using a Modified D5887 Test Method; Applicability of Draintube Drainage Geocomposite for Heap Leach Pad; In-Situ Tensile Strength of Erosion Control Products; Prediction and Analysis of Long-Term Performance of Geosynthetics by Accelerated Index Tests; the Influence of the Geosynthetic Color on the UV Resistance Performance Under Natural and Lab Testing Conditions; Historical Performance of Exposed HDPE Geoweb Walls; and Geomembrane Reservoirs for Storage of Hazardous Liquids.
