In Situ Determination of Density Profiles in Complex

18-06-2019 0183 32 Abstract The nuclear density cone penetrometer ND-CP is an in situ testing device that can provide continuous data on soil density but it measures the composite density of the soil within a spheroid centered at the midpoint between the gamma ray source and the detector A theoretical model for predicting of the ND-CP is proposed and equations for calculating are derived when the ND-CP...

01-06-2018 0183 32 The nuclear density gauge or nuclear densometer is the industry standard for quickly and accurately determining the density moisture content and air voids of a soil This tool is one of the most common forms of geotechnical testing The technician will need a sample of the soil being compacted beforehand so a Proctor density test can be performed...

In Situ Testing CBR Test Site Investigation UK

In-situ California bearing ratio CBR tests in accordance with BS 1377-9 1990 The test is carried out on soils that have a maximum particle size of 20 mm and operates by driving a plunger into the soil at a consistent pace rate This allows for a graphical representation of force vs penetration which in turn allows for the calculation of a...
