Mustafa Saadi Presented on Use, Benefits, Shortcomings of ASTM Methods at D35 Geosynthetics Committee Meeting

Mustafa Saadi, Ph.D., P.E. (Georgia) presented case studies related to geosynthetics testing that Geosyntec has dealt with in the past few years at the D35 Geosynthetics Committee's bi-annual meeting in Atlanta, Georgia on February 5-7, 2020.

As part of the American Society for Testing and Materials (ASTM) D35 committee's continued efforts to solicit feedback from end users of the standards, and develop new standards and methods to meet the end users' needs. Geosyntec was invited to present on the use of relevant ASTM methods, what some benefits and short comings are, and how that relates to products the designer specifies and oversees the installation of in the field.

Mustafa Saadi is a Senior Engineer based in Georgia with more than 20 years of experience focused on Geotechnical Engineering and Civil Design, Remediation Design and Implementation, and Waste Containment Facility Design.

ASTM Committee D35 on Geosynthetics was formed in 1984. D35 meets twice each year, in January and June, with up to 100 members participating in 45 meetings over three days. The Committee, with a membership of approximately 330 members, currently has jurisdiction of over 155 approved standards that are published in the Annual Book of ASTM Standards, Volume 4.13. A list of each subcommittee, and the portfolio of approved standards and work Items under construction are available from the List of Subcommittees, Standards, and Work Items below.

Over 12,000 ASTM standards operate globally. Defined and set by themselves, they improve the lives of millions every day. Combined with their innovative business services, they enhance performance and help everyone have confidence in the things they buy and use.

Presentation Description

As part of the ASTM D35 committee's continued efforts to solicit feedback from end users of the standards and develop new standards and methods to meet the end user's needs, Geosyntec was invited to present on the use of relevant ASTM methods, what some benefits and short comings are, and how that relates to products the designer specifies and oversees the installation of in the field.

Mustafa Saadi presented to the D35 bi-annual meeting attendees a few case studies that Geosyntec dealt with the last few years related to geosynthetics testing. Topics presented and discussed included:

  • Determination of number of constrictions and other design criteria for geotextile filters
  • Variability in testing results of internal and interface shear strength of geosynthetic clay liners
  • Specifying and testing hydraulic transmissivity of drainage layers to better reflect field conditions
  • Evaluation of loss of asperity and shear strength in soft geomembranes due to field installation or movement effects
