Soil stabilization is the process whereby soils and related materials are made stronger and more durable by mixing with a stabilizing agent. These techniques are used for road construction in most parts of the world, although the circumstances and reasons for resorting to stabilization vary considerably.

This publication provides introductory technical guidance for civil engineers and other professional engineers and construction managers interested in stabilization of soil for pavements. Here is what is discussed: 1. INTRODUCTION, 1.1 PUPOSE, 1.2 SCOPE, 1.3 DEFINITIONS, 1.4 USES OF STABILIZATION, 2. SELECTION OF ADDITIVE, 2.1 SOIL TYPES AND ADDITIVES, 2.2 USE OF STABILIZED SOILS IN FROST AREAS, 2.3 THICKNESS REDUCTION FOR BASE AND SUBBASE COURSES, 3. DETERMINATION OF STABILIZER CONTENT, 3.1 STABILIZATION WITH PORTLAND CEMENT, 3.2 STABILIZATION WITH LIME, 3.3 STABILIZATION WITH LIME-FLY ASH (LF) AND LIME-CEMENT-FLY ASH (LCF), 3.4 STABILIZATION WITH BITUMEN, 3.5 STABILIZATION WITH LIME-CEMENT AND LIME-BITUMEN

LIME TREATMENT OF EXPANSIVE SOILS.

For many years, various forms of lime, including products with varying degrees of purity, have been utilized successfully as soil stablizing agents. The state of the art in lime treatment based on a comprehensive analysis of current practice and technical literature is presented in this report. References are included for more information.
