SHRP 2 Demonstration: Infrared Bar for QC/QA, from the Transportation Research Board

More details at http://TRB.org/SHRP2 This video shows a demonstration of an infrared bar being used for quality control and measurement of new hot mix asphalt layers during paving operations. This demonstration was part of Renewal Project R06C: Using Both Infrared and High-Speed Ground Penetrating Radar for Uniformity Measurement on New Hot Mix Asphalt Layers. This project is demonstrating these technologies to assess hot mix asphalt density and segregation in the four AASHTO regions, and will recommend how these technologies can be incorporated into existing department of transportation specifications for construction quality assurance.
