ASTM C702

Reducing Samples of Aggregate to Testing Size

Applicability: ASTM C702 is a standard practice for reducing large field samples of aggregate (fine, coarse, or mixtures) to accurate, representative, and manageable sizes for laboratory testing. It covers three methods—mechanical splitting, quartering, and miniature stockpiling—to minimize variations between the field sample and the test sample, ensuring reliable results.

Purpose: The primary purpose of ASTM C702 is to ensure that the reduced, smaller sample remains representative of the original, larger, bulk, or field sample.
