STABILIZATION OF SOIL WITH LIME

ESTABILIZACION DE SWELOS CON CAL

Soil stabilization with lime is used to improve clayey subgrades and bases of secondary roads. The chemical and physical reactions triggered off by lime stabilization are investigated, and two criteria for quality control are proposed: (1) fineness and (2) percentage of useful lime, e.g., lime capable of physically and chemically reacting with the soil and giving rise to changes in the structure of the latter resulting in cementation. Variations in atterberg limits, CBR values, density, etc., resulting from the addition of lime are discussed, and details are given of the tests to be conducted for determining the proportioning of the mixtures. It is concluded that: (1) small percentages of lime (1.5 to 8%) increase the workability and strength of plastic soils, prevent variations in volume, and increase imperviousness; (2) curing methods have a marked influence on results; (3) lime stabilization is not suitable for soil containing organic matter. /TRRL/
