ABSTRACT
Soil stabilisation with lime and with cement has proved suitable for roads, highways, railways, airfields, and for several special measures (e.g. embankments, backfill of retaining structures), and it is increasingly used for contaminated land and slope stabilisation. The paper focuses on comprehensive test series with cohesive soils which have been running since the year 1963. Laboratory tests have involved the repeated determination of the following parameters: density, Atterberg limits, Proctor values, compressive and tensile strength, permeability, shear strength, and freezing-thawing behaviour. Comparative tests have been performed with lime, lime + cement, and with cement to demonstrate the different behaviour of soil stabilisations. Short and long-term reactions between soil and additives are also reported, including the results from site observations, and finally, practical recommendations are given.
