What condition is required for coarse aggregates when using a mechanical splitter?

When using a mechanical splitter for coarse aggregates, the most favorable condition is that any condition is acceptable. This means that the aggregates can be processed whether they are wet, dry, or have some surface moisture. The key is that the mechanical splitter is designed to handle various moisture conditions without compromising the integrity of the sample being obtained.

Other conditions, such as requiring aggregates to be completely dry or having specific moisture content, could introduce issues such as segregation or inaccurate sampling due to the particles sticking together. Therefore, the fact that a mechanical splitter can function correctly under a variety of moisture conditions makes it a versatile and practical tool in aggregate testing.
