Details

Chemical soil stabilization designers rely on either empirical data or past experience coupled with engineering tests. TRB will host a webinar on Thursday, April 14, 2021 from 1:00 to 3:00 PM Eastern to address the importance of considering soil mineralogy together with engineering tests to identify the suitable type and application rate of chemical stabilizer for soils. Presenters will provide a brief overview of geochemistry in chemical soil stabilization and present case studies as examples. They will discuss correlating advanced mineralogical characterization methods such as X-ray diffraction and themogravimetric analysis with conventional engineering tests. Presenters will also go over the concept of geochemical modeling as a tool for predicting formation of deleterious and pozzolanic products in lime-treated clayey soils.

 

This webinar was organized by TRB’s Standing Technical Committees on Stabilization of Geomaterials and Recycled Materials; Geo-Environmental and Climatic Impacts of Geomaterials; Transportation Earthworks; and Geotechnical Instrumentation and Modeling.

 

Some registrants will need to pay $95 to attend this webinar. Sign into MyTRB.org to view registration information.

Webinar agenda and presenters

 

  1. Overview of applying geochemistry in chemical soil stabilization: Pavan Akula, Texas A&M University
  2. Correlating advanced mineralogical characterization methods with conventional engineering tests: Anand Puppala, Texas A&M University
  3. Case studies of geochemical modeling for material selection and dosage optimization: Narain Hariharan, Graymont
  4. Question and answer session: Moderated by Erol Tutumluer, University of Illinois at Urbana

 

The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.

 

Learning Objectives

 

At the end of this webinar, participants will be able to:

  1. Determine the role of mineralogy in chemical soil stabilization.
  2. Describe the basics of mineralogical tests such x-ray diffraction and thermogravimetric analysis.
  3. Apply appropriate modeling techniques to mineralogy.

 

Professional Development Hour Information

Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 2.0 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.

Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.

TRB will report credits earned to the Registered Continuing Education Program (RCEP). Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, D.C., 20005.
