The preceding methods are specific for use with fine aggregates; however, Hossain, Parker, and Kandhal (2000) report on the development of a similar procedure for coarse aggregates. ASTM C 29 can be used to determine a compacted (by rodding or jigging) or uncompacted (shoveling) void content of coarse or fine aggregate.
