Laboratory Repeatability of the Hamburg Wheel-Tracking Device and Similar Wheel-Tracking Devices
The objective of this research was to assess the repeatability of HMAC moisture susceptibility testing using the Hamburg wheel-tracking device and similar equipment. The tests were performed round-robin-style among seven laboratories. The seven participants were the University of Arkansas, the Colorado Department of Transportation (CDOT), the Federal Highway Administration (FHWA), Koch Materials Company, Superfos Construction, Inc., and Utah Department of Transportation (UTDOT). All the steel-wheeled devices showed very good repeatability during the testing of the polymer-modified asphalt gravel mixture; however, the repeatability was poor during testing of the limestone aggregate mixture. There was less variation within the data collected for Helmut Wind manufactured devices compared to the amount of variation from all the wheel-tracking devices.
