Technologies to Enhance Quality Control on Asphalt Pavements (R06C)

Real-time, high-speed nondestructive testing (NDT) of asphalt pavements during construction can greatly improve quality, durability, and performance, stretching highway dollars and extending service life. Technologies to Enhance Quality Control on Asphalt Pavements (R06C) offers products aimed at providing real-time testing of potentially 100 percent of the pavement area, providing much more inspection coverage than existing methods in hot- or warm-mix construction. R06C includes two products:

• Paver Mounted Thermal Profiler, which measures thermal segregation
• GPR Rolling Density Meter (RDM) system, which measures density

Through an equipment purchase and demonstration program, showcase, and targeted workshops, selected states are receiving hands-on experience using these technologies under varying conditions.

• Veta - Intelligent Construction Tool
  • Veta is a map-based tool for viewing and analyzing geospacial data. Veta can import data from various intelligent compaction (IC) machines and MOBA PAVE-IR thermal bars and scanners to perform editing, data layering, point testing, and analysis. Veta displays compaction information in easy-to-read formats, including graphs and maps. For more information and to download Veta click here.
  • The Transportation Pooled Fund Study supporting Veta is found here: “TPF-5(334) Enhancement to the Intelligent Construction Data Management System (Veda) and Implementation”

• These states implemented the R06C Paver Mounted Thermal Profiler technology through the Implementation Assistance Program: Alabama, Alaska, Illinois, Maine, Missouri, New Jersey, North Carolina, Virginia, West Virginia, and Eastern Federal Lands.
• These states implemented the R06C GPR Rolling Density Meter technology through the Implementation Assistance Program: Maine, Minnesota, and Nebraska.
