This publication provides introductory technical guidance for civil engineers, geotechnical engineers and other professional engineers and construction managers interested in soil stabilization with portland cement. Here is what is discussed: 1. STABILIZATION WITH PORTLAND CEMENT, 2. STABILIZATION WITH LIME, 3. STABILIZATION WITH LIME-FLY ASH (LF) AND LIME-CEMENT-FLY ASH (LCF, 4. STABILIZATION WITH BITUMEN, 5. STABILIZATION WITH LIME-CEMENT AND LIME- BITUMEN, 6. LIME TREATMENT OF EXPANSIVE SOILS.

This report surveys the available information on mixtures of soil and cement. Included are data on (1) properties of cement-treated soil, (2) factors influencing properties of cement-treated soil, (3) uses of cement-treated soil and bituminous surfacing requirements, (4) preliminary surveying, sampling, testing and mix design for cement- treated soil construction, (5) structural design of soil- cement bases, (6) cement-treated soil construction, (7) engineering control of construction, and (8) field performance of soil-cement base courses.

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.

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.
