SOIL STABILIZATION USING LIME

STABILISERING MED KALK

In Sweden the use of lime for soil stabilization was introduced as late as in 1957. This article describes the experiences gained since then. Methods, equipment, practical hints and fields of application are presented. All soils containing clay or clayish silt can have their bearing capacities much improved by adding lime, mixing it thoroughly with the clay to a depth of 15 cm and compacting the mixture. An increase in bearing capacity can be observed after a few days but further improvement will continue for 1-5 years. An admixture of 10 kg quick lime (80% active cao) or 14 kg slaked lime (80% active ca(oh)2) per M2 improves the bearing capacity of the top soil so that it is equal to that of a 40-50 cm thick gravel base course on the same ground. As the abrasion resistance is low, a 15 cm deep gravel layer above the stabilized surface is necessary to withstand traffic load. Vibrating rollers are not suitable for compaction. /TRRL/
