Webinar: Next Generation TSDD Technology — Turning Network Data into Smarter Maintenance Decisions
August 11, 2026 | 3:00 PM EST
Presented in partnership with GeoSolve Engineering Consultants
ICC-IMS invites DOT and municipal agency partners to join us for a technical deep dive into the latest generation of Traffic Speed Deflectometer Device (TSDD) technology and how the data it generates can directly power your agency’s pavement preservation and rehabilitation programs.
Why it matters:
- Full network coverage: Continuous structural data across the entire road network, not just isolated test points
- Highway-speed collection: No lane closures, no traffic control, no disruption
- High-density data: A reading approximately every 20mm, 1,000x more data than legacy TSD systems
- Faster, more cost-effective network surveys
What you’ll learn:
- How 5th generation TSDD compares to FWD and earlier TSD technology
- How TSDD data converts to an FWD-equivalent deflection bowl for familiar back analysis (layer moduli, remaining life, rehab design)
- The Preventive Maintenance Index (PMI) — catching pavement distress before it’s visible on the surface
- How Estimated Poisson’s Ratio (ePR) flags subsurface saturation, one of the biggest drivers of pavement failure — and points to the lowest-cost fix: drainage
- Real-world case studies from state and local agency deployments
Who should attend:
- DOT pavement management, asset management, and materials/design engineers
- Municipal and county public works and engineering staff
- Agencies evaluating network- or project-level data collection programs
- Anyone planning, budgeting, or prioritizing pavement preservation work
Presenters from GeoSolve Engineering Consultants will lead the technical presentation, with ICC-IMS providing insight on program delivery and how TSDD fits within our broader data collection offerings.
