    Proctor Compaction Test Equipment

    Proctor Compaction test equipment from Karol-Warner features our Soil Density Molds, which are manufactured to ASTM and AASHTO standards, and Sample Ejectors to easily remove compacted soil samples from the molds.

    Proctor Compaction testing dates back to the early 1930s when University of California, Berkeley student Ralph R. Proctor first developed a method for evaluating maximum soil density. The test has changed slightly over the years but is still the most widely recognized method for determining the relationship between water content and the dry unit weight of soil used in construction.

    Proctor Compaction Test Equipment
    • Soil Mechanical Compactor is used for standard Proctor compaction. It features automatic counting of hammer blows and shutoff to a preset number. The model accommodates 4in or 6in soil compaction molds.
    • Soil Density Molds (Proctor Compaction Molds) are available in 4in (102mm) and 6in (152mm) diameters. Mold, Collar, and Base components can be purchased separately.
    • Stainless Steel Straightedges are available unmarked or with laser-engraved graduations from 0 to 6in with 0.5in increments for monitoring approximate lift thicknesses. Both are in accordance with many ASTM and AASHTO test methods.
    • Sample Ejectors are used to removing soil samples from Soil Density (Proctor Compaction) Molds, CBR Molds, and LBR Molds. Sample Ejectors are available in 4in (102mm) or 6in (152mm) models and can be adapted to extrude soil from smaller Shelby tube samplers.
    • Soil Pocket Penetrometer is used in the lab or field for quick estimates of the unconfined compressive strength of cohesive soils.
    • Calcium Carbonate Apparatus determines the presence of calcium carbonate (CaCO3) in soils and soft rock by using the gasometric method.
