Evaluation of Infrared Technology (Pave IR) and GPR for Uniformity Measurements During Asphalt Placement

This project will evaluate implementation of infrared (IR) imaging — recently proposed by the SHRP2 program — for temperature uniformity measurements on new hot-mix asphalt (HMA) layers. Uniformity of HMA materials is critical to the durability and performance of asphalt. Segregation and inadequate and non-uniform density continue to be major construction-related problems around the U.S., adversely impacting pavement service life. Commonly used quality control testing procedures only provide limited information on the overall uniformity of HMA. Acquiring information that is real-time, non-destructive, and which covers the full pavement width for thermal uniformity will help improve HMA quality. Kentucky Transportation Cabinet (KTC) will also evaluate a ground penetrating radar (GPR) rolling density device.
