Quality control of profilometers
It is important to maintain a known quality in the test data. For many years, VTI has tested and made comparative measurements of profilometers that are used when making road condition inventories and for functionality tests of surface designs.
VTI has carried out assignments as a part of international projects, for the Swedish and Finnish Transport Administrations, the German Federal Highway Research Institute (Bast) as well as users and manufacturers of measuring equipment.
VTI is in possession of a number of pieces of equipment that can be used as reference, and well thought out methods have been prepared for how these tests should be done.
