The original Dynamic Cone Penetrometer (DCP) was developed in 1959 by the late academician saint george F. The DCP uses a 15 lb (6.8 kg) nerve mass tumbling 20 in (50.8 cm) that strikes the anvil to cause onset of a 1.5 in (3.8 cm) diameter cone (45° apex angle) that has been sitting in the poorest of a jack augered hole. The blows required to drive the embedded chamfer a wisdom of 1-3/4 in have been related to by others to N values derived from the Standard Penetration mental measurement (SPT). The bevel can be replaced with a plated Drive electronic device Assembly for group of 3 x 10 in (7.6 x 25.4 cm) tube samples in ability augered holes. happening has shown that the DCP can be used efficaciously in augered holes to depths of 15 to 20 ft. The S-200 DCP and hand tool Test Set for 10 ft depth includes: As a related item, the Sleeved Drive Hammer, S-20000, has been studied to give a safe means of conducting the DCP effort in accordance of rights with ASTM STP-399, the most wide constituted portable method for evaluating asset and density of soil, in situ.
Dynamic Cone Penetration Test | Pavement Interactive
The impulsive cone cell Penetration Test provides a measure of a material’s in-situ resistance to penetration. The trial is performed by driving a metal cone cell into the material by repeated striking it with a 17.6 lb (8 Kg)weight born from a spacing of 2.26 feet (575 mm). The penetration of the cone is calculated later on each blow andis recorded to provide a continuous measure of cutting off resistance up to 5 feet beneath the ground surface.
ASTM D1586 - 11 Standard Test Method for StandardPenetration Test (SPT) and Split-Barrel Sampling of Soils
Soil deposits containing gravels, cobbles, or boulders typically event in penetration refusal and harm to the equipment. This mental measurement know-how provides a disturbed soil sample for moisture content determination and laboratory identification. illustration quality is mostly not appropriate for advanced laboratory testing for application properties.
