INVESTIGATION AND ASSESSMENT OF COHESIVE SOILS FOR LIME STABILISATION

This paper outlines an approach to the investigation of sites where lime stabilisation is being considered as an option for inclusion in road pavement layers. Although lime stabilisation is here considered in isolation, it is recognised that the investigation of lime stabilisation may typically be part of a larger ground investigation of a site for a proposed road and its associated structures. Before a ground investigation can be planned, it is necessary to know the criteria for assessing the material to be stabilised. The UK Department of Transport (DoT) has specified these criteria for road schemes, and identifies two material types: (1) material suitable for lime stabilisation to form capping; and (2) lime stabilised material. A good site investigation is essential for allowing a confident decision to be made about including lime stabilisation as an option in a road scheme. The three key elements of such an investigation are the desk study, the ground investigation, and the laboratory testing. The specific relationships of these elements to a lime stabilisation investigation are discussed. An approach to site investigation has been emphasised, that is specifically designed to assess the suitability of cohesive materials on site for the lime stabilisation process.
