The SAND 500 road pavement analysis system is used for detailed registration and evaluation of damage to bituminous, concrete and small-size concrete road surfaces.
The evaluation takes place in two stages:

  1. Scanning the road pavement using broadband laser scanners placed on the test vehicle and preparing photographic documentation of the road environment using cameras installed on the vehicle (mobile part of the system).
  2. Data processing at a stationary station (fixed part of the system).
    As a result of the road test using the SAND 500 method, we obtain data consisting of:
    – monochromatic laser images;
    – hypsometric road pavement mapping, where the individual unevenness corresponds to the colours according to the assigned scale.

Post-processing allows you to receive documentation consisting of:
– graphical mapping of the road pavement with precisely located and dimensioned damage;
– photographic inventory of road pavement marking;
– the results of the measurement of reliable rut depths according to the SOSN classification;
– maps with the actual location of the measurement sections;
– photos from two cameras in Full HD quality.


The SAND 500 is fully suitable for current pavement condition assessments, for periodic road inspections and for solving existing problems related to planned pavement repairs, construction and reconstruction of roads.
Advantages of the system:
– repeatability of test results,
– objectivity – high accuracy,
– elimination of interference,
– graphic mapping of the surface of the tested road, precise location of the types of damage, as well as their dimensioning.
The damage report during the performed test is recorded in the damage table. It contains:
– time and place of measurement;
– measurement length with accurate GPS data;
– measurement direction of the section;
– type of tested surface;
– the number of the section of the tested road with a description of the damage.


The description on the damage table includes an assessment of elements such as:

  • asphalt cavities;
  • bumps, breakthroughs;
  • transverse cracks of low and high harmfulness;
  • longitudinal cracks of low and high harmfulness;
  • mesh cracks of low and high harmfulness;
  • pavement collapses and subsidence;
  • folds and humps;
  • transverse deflections;
  • local bulges;
  • transverse and longitudinal bulges;
  • patches of low and high harmfulness;
  • ruts;
  • pavement irregularities and other damage.
