3D GPR applications for network level testing, SPR-4915

The Federal Highway Administration (FHWA) awarded the Indiana Department of Transportation (INDOT) a Formula Grant totaling $123,183.91 on June 9, 2025, under the Highway Planning and Construction program (CFDA 20.205) to support 3D Ground Penetrating Radar (GPR) Applications for Network Level Testing (SPR-4915). This project leverages advanced ground-penetrating radar technology to conduct non-destructive diagnostic testing of Indiana's highway infrastructure at the network level, enabling data-driven assessment and analysis of pavement conditions and subsurface conditions across the state's transportation network.

The award supports INDOT's specialized research and diagnostic initiatives that enhance infrastructure preservation and maintenance decision-making capabilities. As part of the broader Highway Planning and Construction program authorized under the Infrastructure Investment and Jobs Act (IIJA), this funding aligns with the federal government's commitment to advancing innovative technologies for transportation infrastructure assessment, preservation, and improvement. The research outcomes from this 3D GPR testing initiative will inform strategic maintenance and rehabilitation priorities across Indiana's diverse highway network, ultimately supporting more efficient stewardship of federal transportation investments.
