Micro-Deval

The Micro-Deval method is a test method used to evaluate the abrasion resistance and durability of aggregates, especially for use in concrete and asphalt. 

The testing machine mainly consists of a heavy steel frame on which stainless steel cylinders can be mounted. It is supplied with a sound-insulated safety enclosure in accordance with CE requirements. 

The method measures the extent to which aggregates are worn down when subjected to mechanical loading in the presence of water. This provides an indication of the material’s resistance to wear and degradation. 

The aggregate is divided into specific size fractions and weighed before being placed in a steel cylinder together with water and magnetic stainless steel balls.
The container is then rotated to simulate wear. 

The Micro-Deval test is useful for quality control of aggregates, as it provides information on how materials will perform under load and in different environmental conditions. Materials with a low wear percentage are more durable and better suited for use in construction. 

The method is recognized for its accuracy and cost-effectiveness, and it requires smaller sample quantities compared to other methods, such as the Los Angeles test.
