The 3D laser texture measuring device measures the road surface with high resolution. The measuring device is mobile and can be used in the laboratory as well as in istu. The measurement data is evaluated in Matlab for specific applications.


  • Grain loss of open-pored asphalts
  • Grain and substance loss of traffic surfaces
  • Texture measurements for acoustic calculations (program SPERoN®)
  • Texture measurements for skid resistance assessment (macro texture, aquaplaning risk)

Characteristic Data

  • Lateral resolution: 150 µm
  • Resolution in z-direction: 019 µm
  • Measuring field size: max. 365 mm x 600 mm
