ABSTRACT:
Apparatus for measuring two parallel spaced surface profiles is disclosed. The apparatus disclosed has dual laterally spaced beams linked to a transport device shown as a trailer that is towable by a motor vehicle. Each beam has a profiling wheel that measures road surface deviations and transmits the resulting measurements to a recording device. The beams are foldable and stowable on the trailer for transport of the apparatus between measuring sites.
