ABSTRACT
In a first step to create a standard method for making stabilised peat samples in laboratory, experiences from Finland and Sweden (Lulea University of Technology and Swedish Deep Stabilisation Research Centre) have been reviewed. As a peat has a very high compressibility, the standard method for manufacturing stabilised samples of clayey soils can not be used. During curing time, a load is applied on stabilised peat samples and drainage of pore water is allowed. This method gives repeatable and reasonable results. There are several factors in the manufacturing process of stabilised peat samples, that should be considered before a standard method is established. Main factors discussed and presented in this paper are: size of the stabilised samples, spreading of the results, mixing time, mixing device, curing time and applied load during curing time. Also the stabilisation effect of different peat qualities have been studied, as well as how stabilised peat samples, exposed to freeze/thaw cycles, are affected.
