Pavement Rutting Repeatability and Bias Error Checks for a Laser Profilometer
  • Publication no: AGAM-T012-16
  • Published: 13 May 2016

This test method defines the procedure for conducting repeatability and bias of measurement checks for rut measurements made by a laser profilometer.

The bias check included in this method is used to determine whether there is a systematic drift in a laser profilometer’s measurements over time. It does not cover the collection of reference data from a separate measurement device.
