Ground modification methods improve poor soil conditions, enable construction on marginal sites, and reduce the risk of transportation infrastructure failure. These methods help accelerate construction in challenging geotechnical environments. TRB will host a webinar on Thursday, July 30, 2026 from 12:00 PM to 1:30 PM Eastern that will present a structured framework for developing performance-based guidelines for ground modification methods used in transportation infrastructure, including embankments, bridge approaches, and other structures. Presenters will share a literature review, methodology development, and proposed performance-based specifications for selected ground modification methods, as well as the steps taken to implement guidance documents in state agencies’ specifications and projects.
