2005 ACPA Profiler Repeatability Tests

Karamihas, S. 2005. 2005 ACPA Profiler Repeatability Tests.

This report describes testing of profiler repeatability on four sections of textured concrete, including transverse tining, longitudinal tining, diamond grinding, and light turf drag. The profilers included only devices with a large height sensor footprint. The evaluation of repeatability was based on the level of cross correlation between repeat profile measurements after the application of the filters used in the IRI calculation. TYPE UMTRI report
