Micro-Deval test

The purpose of the Micro-Deval test is to determine the resistance of aggregate particles to wear by mutual friction. For some rocks, this wear resistance differs between dry and wet conditions, so the Micro-Deval test is generally performed either in the presence of water (wet Deval) or dry (dry Deval).
The Micro-Deval test is performed on the following size fractions:

  • 4/6.3 mm;
  • 6.3/10 mm;
  • 10/14 mm;
  • 25/50 mm.

For the Micro-Deval test, CiviLab applies the following standards:

  • ASTM D6928-17;
  • BS EN 1097-1;
  • NA 5129;
  • NF EN 1097-1;
  • NF P18-572.
