Aggregate Compaction / Density

Bulk Density and Void Content of Fine and Coarse Aggregates

Returns the bulk density and void content of a material in a dry condition. Run alongside C127 or C128 to obtain relative density and saturated surface dry density.

Lightweight Particles in Fine and Coarse Aggregates

Returns the percentage by mass of lighweight particles that have specific gravities of less than 2.4 (chert) and less than 2.0 (coal / lignite).

Density (Specific Gravity) and Absorption of Coarse Aggregates

Run on materials retained on the #4 sieve. Samples containing fractions of fine and coarse particles may need both ASTM C127 and C128 run.

Density (Specific Gravity) and Absorption of Fine Aggregate

Run on materials smaller than the #4 sieve. Samples containing fractions of fine and coarse particles may need both ASTM C127 and C128 run.

Standard Effort Laboratory Compaction of Soils (“Proctor Test”)

Produces the theoretical maximum compacted density of a sample, and the optimum water content at which that density occurs.

Modified Effort Laboratory Compaction of Soils (“Proctor Test”)

Produces the theoretical maximum compacted density of a sample, and the optimum water content at which that density occurs.

Proctor Correction Procedure for Oversize Particles

Run alongside ASTM D698/D1557 to determine the effects of moisture retained in large particles on proctor test results
