THE USES OF LIME IN GROUND ENGINEERING: A REVIEW OF WORK UNDERTAKEN AT THE TRANSPORT RESEARCH LABORATORY

The paper considers current and recently completed research on applications in highway capping, bulk fill, railway track bed, slope stability and the processing of contaminated materials. The benefits and the technical support for the use of lime are outlined. Guidance is given on design, including site investigation strategy, laboratory testing and application. The main critical soil properties are discussed and their detection and evaluation briefly described. Consideration is given to the chemical and geotechnical effects that stabilisation may have on cohesive soil. The paper is concerned only with the use of quicklime. Examples are given of the treatment of a railway track bed, the modification of bulk fill and the use of lime piles and columns on ageing earthwork slopes. Advice is given on the design of stabilised capping and the factors involved in site investigation. For the covering abstract see IRRD 887532.
