Measurement of profile
VTI carries out various types of profile measurement and have a number of different kinds of equipment ready for use.
Surface testing vehicle
The VTI Laser RST (Road Surface Tester) can measure a road's longitudinal and cross profile, its undulating profile and its texture profile according to the Swedish Transport Administration (Trafikverket) specifications (pub:2009:78 MB121 and 2009:79 MB 122).
Primal profile tester
Primal, VTI's profile tester, measures the profile of the surface crossways and lengthways with great precision between two points. Primal can be used on roads, runways, docksides, industrial surface areas or other paved surfaces where the profile of the surface needs to be determined with a high degree of accuracy.
The VTI wear profilometer can measure the abrasion of the road surface caused by studded tyres. By taking measurements in the autumn and spring, the wear caused by studded tyres over the winter can de determined with great accuracy. The wear profilometer can also be used for other paved surfaces in order to assess wear or abrasion.
VTI can offer the texture profile measurement of a road surface, which can be used, for example, for the calculation of MPD (Mean Profile Index) or megatexture according to the Swedish Transport Administration specifications (Trafikverket method description pub:2009:78 MB121 and 2009:79 MB 122).
