Micro-Deval Test. Is an abrasion loss test carried out on fine or coarse aggregate samples that are partially submerged in water. The Micro-Deval Apparatus is essentially a ball mill using stainless steel jars positioned on a roller mechanism. Samples, with water and an abrasive charge of steel balls, are placed in the jars and then rotated for a prescribed time at a specified speed.
