Relative Compaction Set Replacement Parts

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.

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.
