Product Description
Plate Bearing Test Apparatus
- Dynamic Cone Penetrometer (DCP) It is used for rapid in-situ measurement of the structural properties of existing road pavement constructed with unbound materials.
- The unit incorporates an 8 Kg weight having a drop of 575 mm, fitted to end of the shaft is a 20 mm diameter cone. With the standard DCP measurements can be made down to a depth of approximately 850 mm.
- Reading are taken after a set number of blows, changing the number according to the strength of layer being penetrated. For good granular bases,
- readings every 5-10 blows are satisfactory, but for weaker sub-base layers and sub grades, readings every 1-2 blows may be appropriate.
- The DCP requires Three operators, one to hold the instrument in a vertical position, one to raise the hammer and let it fall and one to record the results. A typical test takes only a few minutes, providing a very efficient method of obtaining information, which would otherwise require the excavation of test pits. Where pavement layers have different strengths, boundaries can be identified and layer thickness determined.
- Supplied complete in a nice Wooden Carrying Case.
