The cone is pushed using steel rods that are able to be connected to each other in 1-meter lengths as the depth increases. Where pavements layers have different strengths the boundaries can be identified and the thickness of the layers determined. The reusable types can be cleaned in an ultrasonics bath. Most penetrometers measure a single u-value, although dual-, triple-, and even quad-element piezocones are also available e. As rod sizes are nor- mally Copyright - Geotechdata.
The friction reducer is merely an enlarged section of rods e. This reduces costs associated with mobilizing a dedicated CPT truck. Not a MyNAP member yet? GE - Cone Drop Test Apparatus Method to determine the resistance of geosynthetics to penetration by a steel cone dropped from a fixed height, as a simulation of dropping sharp stones on their surface. His research has embraced centrifuge model testing, numerical analysis and plasticity solutions, and he has made particular contributions in the area of site investigation of soft soils.
