Stabilization additives are used to increase the strength and stiffness of road foundations in weak and susceptible soils. Numerous additives exist for improving performance of aggregate base and subgrade layers. TRB will host a webinar on Tuesday, February 28, 2023 from 2:30 PM to 4:00 PM Eastern that will explore examples and case studies using conventional and nonconventional additives. Presenters will discuss non-proprietary additives that are commonly used and alternative proprietary additives that are garnering new interest. Presenters will also share compaction methods to improve pavement foundation layers.

This webinar is a follow on to the TRB Annual Meeting Workshop: Performance of Stabilized Pavement Foundations With Conventional and Unconventional Stabilizers held on Friday, January 22, 2021.

This webinar is sponsored by the TRB Standing Technical Committees on Stabilization of Geomaterials and Recycled Materials, Transportation Earthworks, and Geotechnical Instrumentation and Modeling.

Registration is free for employees of TRB sponsors as well as Titanium and Cobalt Global Affiliates. The registration rate for all other attendees is $100. Sign into MyTRB.org to view registration information. Contact Patrice Davenport to inquire about becoming a TRB sponsor or global affiliate organization.

A recording will be sent to all registrants after the webinar.

Webinar agenda and presenters

• Sustainable pavement foundations with chemically stabilized quarry byproducts – Erol Tutumluer, University of Illinois, Urbana-Champaign
• Novel stabilization methods for sulfate soils using laboratory and field studies – Anand Puppala, Texas A&M University
• Improving stabilized full depth reclamation with intelligent compaction – John Siekmeier, Minnesota Department of Transportation

Learning Objectives

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

• Determine the impact of different stabilizers on geomechanical properties of pavement foundation geomaterials
• Apply different stabilization techniques for pavement foundation improvement

Professional Development Hours

Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 1.5 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.

Pre-registration is required. Once the webinar starts, you will be unable to register. Individuals that are registered for a webinar but do not receive their confirmation emails due to their organization’s internal firewalls should contact TRB Helpdesk for assistance in signing in.
