The Micro-Deval is used to test the resistance of fine/coarse aggregates to degradation by abrasion. This testing of fine/coarse aggregates determines their abrasion loss in the presence of water and an abrasive charge. Test results are helpful in judging the suitability of fine/coarse aggregates subject to weathering and abrasive action when adequate information is not available.

 

Principle of operation
A pre-soaked aggregate sample is placed in the jar with a fixed volume of water and a fixed quantity of 9.5mm S.S. balls. The unit is then put into rotation for a known period of time. The period of time depends on the initial grade of the sample. At the end of the cycle, the sample is removed and the aggregate quality is determined by the percentage of loss by gradation.
