Method for determining the abrasion value of aggregates ( AAV )

PROPERTIES OF SANDS EN 1097-8

This method makes it possible to determine the abrasion value of road aggregates.

The sands produced by the SNL are the sands used to produce the test specimens.

Formulation

The fine sand less than 0.300 mm is intended for setting the aggregates at the bottom of the mold.
Abrasive sand is fine siliceous sand containing at least 96% silica. All the sand must pass through a 0.85 mm sieve and be retained on the 0.300 mm sieve. In addition, 75% of the fine sand must pass through the 0.600 mm test sieve and be retained on that of 0.425 mmm (it is kept dry in paper bags with a polypropylene fold): it will then be mixed with the resin.

Conditioning

The bags are 25 kg
