Technologies to Enhance Quality Control on Asphalt Pavements (R06C)
Product Overview

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:

  • A Paver Mounted Thermal Profiler, which measures thermal segregation
  • The 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.
