Symposium on Shear Testing of Soils

(In-person only event)

Date: January 29, 2025 - January 30, 2025

Event Location:  Hyatt Regency Houston, Houston, Texas, United States

Organized by: ASTM Committee D18 on Soil and Rock



About the Event

The Symposium on Shear Testing of Soils will be held January 29, 2025 - January 30, 2025. The symposium is organized by ASTM Committee D18 on Soil and Rock, and will be held at the Hyatt Regency Houston, Houston, Texas, United States in conjunction with the standards development meetings of the committee. The language of the symposium will be English.


Objective and Scope

This symposium will provide a forum for experts from around the world to discuss the need for new or revisions to current ASTM standards used in laboratory ring shear, direct shear, direct simple shear, and triaxial compression testing of soils, which includes specimen preparation, reconstitution, consolidation, and drainage during consolidation and shearing. This symposium also will provide a forum for experts to discuss the need for new or revisions to current ASTM standards used in field shear testing, e.g., field vane shear, T-Bar, cone penetrometer, pressuremeter, and any other field shear test.

Papers are sought on the following topics:

  • Specimen Preparation
    1. Undisturbed/Intact
    2. Reconstituted
    3. Ball-Milling
    4. Index Property Testing
    5. Interface Testing
  • Drained Torsional Ring Shear Testing
    1. Peak Strength
    2. Fully Softened Strength
    3. Residual Strength
    4. Interface Testing
    5. Multi-Stage Testing
  • Drained Direct Shear Testing
    1. Peak Strength
    2. Fully Softened Strength
    3. Residual Strength
    4. Interface Testing
  • Drained Triaxial Compression Testing
    1. Peak Strength
    2. Fully Softened Strength
  • Undrained Ring Shear Testing
    1. Peak Strength
    2. Residual Strength
  • Undrained Direct Simple Shear Testing
    1. Peak Strength
    2. Post-Peak Strength
    3. Effects of Cycle Loading
  • Undrained Triaxial Compression Testing
    1. Peak Strength
    2. Post-Peak Strength
  • Field Shear Testing, e.g., vane shear, cone penetration, and T-Bar Testing
    1. Peak Strength
    2. Remolded Strength
    3. Residual Strength


Abstract Submission

To participate in the symposium, authors must submit a 2- to 3-page abstract using the ASTM Extended Abstracts template found below and in the online Abstract Submission Portal no later than September 1, 2023. To ensure your abstract was received into the ASTM database, please email and let us know that you have submitted an abstract. Abstract authors who submit but do not use the extended abstract template will be asked to resubmit using the correct format.

The abstract must include a clear definition of the objective and approach of the work discussed, pointing out material that is new, and present sufficient details regarding results. The presentation and manuscript must not be of a commercial nature nor can it have been previously published. Because a limited number of abstracts will be accepted, be sure that the abstract is complete to allow for careful assessment of the paper's suitability for this symposium. The symposium chair(s) will notify you via email by September 11, 2023 of your paper’s acceptability for presentation at the symposium. If the preliminary abstract is accepted, the author will be requested to submit a final abstract a few months before the symposium. The final abstracts will be distributed in a program booklet at the symposium.


Publication Information

Based on the technical quality of the abstracts, presenters may be contacted to submit a full paper for the planned special issues of ASTM’s Geotechnical Testing Journal (GTJ). The GTJ is focused on publishing papers on new or modified testing methods and procedures, particularly those that may lead to new ASTM testing standards. Only papers that fit the scope of the GTJ will be considered. You will be notified by October 6, 2023, if the Co-Editors of the journal would like you to submit a full paper for a special issue. Please note that all submitted papers are subject to peer review by two independent reviewers.

Manuscripts to be peer reviewed for the special issue are due online at the ASTM Editorial Office no later than January 31, 2024. Papers submitted to the Geotechnical Testing Journal will be peer reviewed prior to publication in the Special Issue. The corresponding author will receive a copy of their paper in an electronic format. All published authors will have the opportunity to purchase reprints of their papers at a nominal cost.


Technical Program

A technical program (presentation times, paper titles, and presenters’ names) will be posted on the ASTM website by October 2024.
