Whether testing in the field or lab, Gilson has the soil compaction test equipment you need to perform Proctor Compaction Tests, determining soil moisture-density relationship and for testing Relative Compaction and Relative Density of granular soils.
ASTM D698 and ASTM D1557 standards, Laboratory Compaction Characteristics of Soil, and AASHTO T 99 and AASHTO T 180 standards, Moisture-Density Relations of Soils – all commonly referred to as Proctor Tests – are widely used in projects to control placement and compaction of soil embankments and other engineered fills. Products offered in this Proctor Compaction & Density category will keep you compliant with ASTM, AASHTO, and other relevant test methods.
- Mechanical Soil Compactors for Standard and Modified Proctor compaction and preparation of California 216 samples. These Mechanical Soil Compactors feature automatic counting of hammer blows and shutoff upon reaching a preset number. Indexing turntable positions the mold for the next hammer drop, ensuring optimum distribution of compaction energy. These units increase accuracy and repeatability and are easy to use, safe, and reliable. Models accommodate 4in or 6in Soil Compaction Molds for Standard or Modified Proctor tests.
- Soil Compaction Molds are used with the California Bearing Ratio (CBR) and Florida’s Limerock Bearing Ratio (LBR) tests, in addition to soil Proctor Density tests. Molds are sold as complete assemblies or as individual components for Density, CBR, and LBR testing.
- Manual Compaction Hammers are available in 5.5 or 10lb masses for use with Standard or Modified test methods. The Gilson Manual Compaction Hammers feature advanced design and stainless steel construction to compact soil specimens into soil molds.
- Automatic Soil Processor can be used to reduce the time spent preparing soil samples for testing. The processor holds up to 40lb (18kg) of cohesive soil that can be processed in fifteen minutes through a replaceable screen into a sample pan.
- Sample Ejectors are available in two styles, one for 4in molds only and the other for both 4 and 6in molds. Gilson's Sample Ejectors feature a 12,000lbf (53.4kN) capacity. Simple operation easily extrudes compacted soil or asphalt specimens.
- Pocket Penetrometer is a handheld device used in the field or lab for classifying cohesive soils. It provides instant estimates of unconfined compressive strength. OSHA requires its use for trenching and excavation inspections.
- Soil Grinder is an alternative method to traditional mortar and pestle methods for sample reduction. Soil samples are automatically reduced to individual particle sizes for testing.
- Proctor Penetrometer Set with components used for measuring penetration resistance of fine-grained soils during laboratory Proctor density testing. The Proctor Penetrometer Set meets ASTM D1558 Standards. This unit is supplied with interchangeable threaded penetration needles and a wooden storage box with a carrying handle.
- Hydraulic Sample Extruder offers one-stroke continuous extrusion using a hydraulic drive system. Damage to sensitive undisturbed soil samples is eliminated. It can be bolted to a benchtop or mounted on the optional Extruder Stand.
- Relative Compaction Test Set with tamper is used to compact specimens using the California 216 impact method. This test set is used for field and laboratory determination of the maximum wet density of soils and aggregates.
- Relative Density Apparatus with gauges, mold, and funnel sets and vibrating tables are geared to determining the relative density of granular soils that typically do not respond well to Proctor moisture-density tests.
- Proctor/Density Accessories include products commonly used for performing lab and field tests on moisture density of soils.
