This project will advance the use of Ground Penetrating Radar (GPR) as a reliable and practical tool for pavement inspection in Pennsylvania by evaluating its capabilities, limitations, and implementation strategies. The research will assess how GPR is currently used by DOTs to measure pavement layer thickness, structural characteristics, reinforcement location, and subsurface distress, while identifying factors that influence data quality and interpretation. Through engagement with state agencies and industry practitioners, the project will synthesize best practices for both network-level asset management applications and project-level site investigations. The effort will culminate in clear, implementable recommendations and guidance to support informed adoption of GPR within maintenance and rehabilitation decision-making processes, complemented by knowledge-transfer webinars to ensure practical uptake by IRISE members.
