Compliance with ASTM D6951, IRC:SP:72
The Dynamic Cone Penetration Test provides a measure of a material’s in-situ resistance to penetration. The test is performed by driving a metal cone into the ground by repeated striking it with a 17.6 lb (8 Kg) weight dropped from a distance of 2.26 feet (575 mm). The penetration of the cone is measured after each blow and is recorded to provide a continuous measure of shearing resistance up to 5 feet below the ground surface. Test results can be correlated to California Bearing Ratios, in-situ density, resilient modulus, and bearing capacity.
Features:
- Well proven, robust design
- Portable and easy to operate
- Tests can be carried out in minutes
- Results correlate well with conventional CBR readings
- Detects layer boundaries and thicknesses
- Ideal in locations where access is difficult (such as coal holes)
Equipment detail:
The 8 kg free fall hammer is lifted and dropped through a height of 575mm. The distance of penetration of the cone tip is then recorded and the cycle repeated. Continuous measurements can be made down to a depth of approximately 850mm or when extension shafts are fitted to a maximum recommended depth of 2 meters. Where sub-pavement layers have different strengths, the boundaries can be identified and the thickness determined.
