Scandinavia. However, there is great uncertainty with regards to strength and deformation characteristics of the resulting stabilized material. Sampling by traditional methods, like geotechnical piston sampling, is unsuitable due to the brittleness and high strength of the stabilized material.
This paper presents the preliminary results of samples collected within lime-cement columns using a Kiso-Jiban GP-Tr sampler to obtain undisturbed, high quality samples from the field. The sampler uses a gel-polymer to lubricate between the sample and the sampler walls to reduce the friction and disturbance of the sampling process.
The method allows for continuous high quality sampling of lime-cement stabilized clay down to great depths. High quality samples allows for determination of material parameters from advanced laboratory tests, e.g. triaxial and oedometer tests, which can be used to investigate the properties of the stabilized material, and thereby determine if the designed strength has been reached.
