Which of the following is a method for splitting aggregates besides mechanical splitting?

Quartering is a method for splitting aggregates that involves dividing a bulk sample into smaller, representative portions. This technique is particularly useful to ensure that the subsamples maintain the same particle size distribution and composition as the original bulk sample.

The process of quartering typically involves laying out the aggregate material in a flat, even layer and then dividing it into four quadrants. The two opposite quadrants are then removed, and the remaining two are combined and further quartered if necessary. This method is widely used in aggregate sampling because it is straightforward and can be performed without specialized equipment, making it accessible for field applications.

Accurate weighing, on the other hand, pertains to the measurement of sample weight rather than splitting. Digital measuring also refers to measurement techniques but does not specifically address the splitting process. Batch sampling implies collecting a pre-defined quantity of material but does not involve dividing the aggregate into smaller portions for testing or analysis. Thus, quartering stands out as the correct and specific method for effectively splitting aggregates.
