International Conference on Deep Mixing - Best Practice and Recent Advances, Deep Mixing ''05

The conference, which was endorsed by leading international professional organisations, took place in Stockholm, Sweden on May 23-25, 2005.

The primary aim of the conference was to provide a platform for information exchange and communication between the main groups involved in the planning, design and execution of the deep mixing process. At Deep Mixing ''05, there was the opportunity to meet colleagues from all over the world for technical, scientific and commercial discussions. In the technical sessions, various aspects of Best Practices and Recent Advances in wet and dry deep soil mixing were discussed.

An extensive installation of lime/cement columns is ongoing for Bärbyleden, a main road connecting the new highway E4 at Uppsala town, about 70 km north of Stockholm. The difficult ground conditions, with deep layers of soft clay require improvement by 330 000 m of columns with diameters of 600-800 mm. Deep mixing is carried out in order to increase the stability of road embankments and to reduce settlements at bridge approach embankments.

Representatives of the National Road Administration (client) and the foundation contractor LCM informed about the construction project, challenges and geotechnical requirements etc.. The installation of lime/cement columns were demonstrated (see photo by Ilkka Vähäaho).
