Relative Compaction Test Set

The Relative Compaction Test Set provides a practical way to establish maximum wet density for soil and aggregate samples using the California impact-compaction procedure. Technicians compact material in a tall split mold and determine the laboratory reference density used to assess field compaction. The manual design makes the procedure accessible without a powered compactor, while quick-release clamps simplify removal of the compacted specimen.

Key Features

• Designed for the California Test 216 impact method for maximum wet density and relative compaction of soils and aggregates.
• The split steel mold opens quickly to remove compacted material with less disturbance and easier cleanup.
• The integrated graduated tamper shaft simplifies determination of compacted specimen height during the test.
• A manual impact system offers a straightforward option for laboratories performing California-specific compaction testing.

Included Items

Split mold with removable base, 10lb tamper, metal leveling piston, piston handling rod and calibration certificate, per the HMA listing.

Lab Manager's Tip

Verify the specified 10lb tamper, 18-inch drop and mold condition before use. California Test 216 uses a particular compaction sequence and reporting basis; do not substitute ASTM D698 or AASHTO T 99 compaction energies.

Typical Applications

California relative compaction testing, soil and aggregate maximum wet density, field density comparisons and roadway subgrade quality control.
