The Swedish Deep Stabilization Research Centre (SD) was established between 1995 to 2006 to perform research, development, demonstration and implementation in the field of deep soil mixing. The Centre comprised of 23 members, including government authorities, contractors, consulting companies, binder producers, universities, a research institute and research funding organisations. The R&D activities in-cluded Experience data-base, Properties of stabilised soils, Function of deep mixing improvements, Execution and Control. The results of the SD activities contribute to the advancement of deep mixing and the knowledge gained encourages the use of deep mixing in a better way. Furthermore, the gained knowledge also gives rise to the use of deep mixing in wider range of soil types and in new applications, e.g. reduction of vibrations at high speed trains and stabilisation / solidification of contaminated ground. The results have been published in two series of publications from the SD. All publications can be ordered from Swedish Geotechnical Institute. Two international conferences have been arranged by the SD, 1999 and 2005, both in Stockholm with a large number of international participants.
