Aggregate Sample Splitters

Sample Splitters, continued Per the ASTM C702 standard, larger field samples need to be reduced to a smaller size for more convenient lab testing purposes. This methodology ensures that the smaller test sample is representative of the entire stockpile. Different sample reduction methods are used depending on the size and condition of the aggregates being sampled.
