LIME STABILISATION FOR NEW ZEALAND ROADS

The purpose of lime stabilization, lime sources and soil suitability for lime stabilization are discussed, and a project feasibility study procedure designed to determine whether lime stabilization is economically viable for a particular situation is suggested. Laboratory testing, mix design and pavement design showing how the lime stabilized layer may be incorporated into the pavement in the most economical way are described. Stabilization construction is comprehensively covered, and quality control measures are reviewed. Agricultural lime, quicklime or burnt lime, and hydrated or slaked lime are considered, and the reaction mechanism and physical characteristics of the lime-soil system are described. The degree of reaction with different soils (clay, organic, volcanic sulphate soil, pozzolanic materials, etc.) is discussed. Recommended laboratory testing, durability testing are described and comments are also made on pavement repair.
