• Abstract:
  This report describes upgrades to the Federal Highway Administration Benchmark Profiler (BP) and the University of Michigan Transportation Research Institute Urban and Low-Speed Profiler (ULSP) and comparison between profiles measured by the two devices. BP and ULSP measurements were compared on six pavement sections at the Illinois Certification and Research Track. The test sections composed a diverse set of macrotexture types. Agreement between profiles was quantified using cross correlation of profile filtered by the International Roughness Index algorithm. Agreement between the two devices and among repeat measurements made by each device exceeded the threshold established for reference quality profilers.
