Soil Density Testing Equipment

• Sand Cone Test Density Sand meets ASTM D1556 and AASHTO T 191 standards. It is free-flowing and uniform, with a bulk density that varies less than 1%.
• Sand Cone Density Apparatus (6.5in) is a plastic jar fitted with a metal valve and cone for soil density testing in accordance with ASTM D1556 and AASHTO T 191. The cone has a 6.5in (165mm) diameter.
• Sand Cone Density Apparatus (12in) is a larger sand cone apparatus for density determinations in gravels and coarse soils. The cone diameter is 12in (305mm).
• Balloon Density Testers (1/20ft³ or 1/13ft³) determine the in-place density of soils in compacted earth fills. The 1/20ft³ unit is for testing soils with 0.5in (13mm) maximum particle size, while the 1/13ft³ model tests soils with a particle size up to 1in (25mm). Water held in the calibrated vessel displaces a flexible balloon into a hole dug in the test area for volume measurements.
• In-Place Density Accessory Kit contains items needed for testing with Sand Cone Density Apparatus or Balloon Density Testers. Items in the kit include plastic sample bags, a pocket dial thermometer with a case, a fine bristle cleaning brush, a chisel, spoon, and a rubber mallet.
• Soil Density Volumeter is designed for portability and quick measurements of cohesive soil density. Its calibrated cylinder has a 30cm³ capacity.
