THE PRESENT AND FUTURE OF SOIL STABILIZATION

RECOGNIZED SOIL STABILIZATION TREATMENTS DISCUSSED ARE: MECHANICAL, CHEMICAL, AND ELECTROTHERMAL. STABILITY IS DEFINED IN TERMS OF COHESION AND EFFECTIVE OR INTERPARTICLE FRICTION. THE PROCESS OF STABILIZATION HAS AS ITS SCOPE THE MODIFICATION OF THESE PARAMETERS. IN MECHANICAL STABILIZATION, FINE-GRAINED SOILS ARE COMBINED TO IMPART THE DESIRABLE PROPERTIES TO THE RESULTING SOIL MASS. CHEMICAL STABILIZATION REFERS TO THE ADDITION OF HYDRATED LIME, PORTLAND CEMENT, BITUMINOUS MATERIALS, AND CHEMICALS CONTAINING LARGE ORGANIC MOLECULES. IN ELECTROTHERMAL SOLIDIFICATION, DIRECT ELECTRIC CURRENT IS USED TO DRAIN FINE-GRAINED SOILS WHICH OTHERWISE CANNOT BE DRAINED OR HIGH TEMPERATURES ARE USED TO CHANGE THE NATURE OF FINE-GRAINED SOILS. THE ROLE THAT MAY BE PLAYED BY POLYMERS IS DISCUSSED. ALL CLAYEY SOILS DO NOT RESPOND EQUALLY WELL TO A SPECIFIC STABILIZATION TREATMENT. DIFFERENCES IN MINERALOGICAL COMPOSITION, SURFACE CHARACTERISTICS, ENVIRONMENTAL EFFECTS SUCH AS PH, ABSORBED ELEMENTS, MICRON-CLAY CONTENTS WHICH DEFY GRAVITATIONAL LAW, INFLUENCE DIFFERENT STABILIZATION RESULTS. ALL SOILS DEPICTED ARE CLAY, BUT THEY DIFFER IN THEIR ACTIVITY, CATION EXCHANGE CAPACITY, AND IN PLACE PH VALUE. CONSEQUENTLY, THEIR RESPONSE TO STABILIZATION TREATMENT IS VERY DIFFERENT.
