THE INFLUENCE OF SOIL STRUCTURE AND STRESS HISTORY ON THE SOIL-WATER CHARACTERISTICS OF A COMPACTED TILL

The influence of initial water content, soil structure and stress history, as it relates to the soil-water characteristic, has been studied and is reported in this paper. The initial water contents selected for this study represent the dry of optimum, optimum and wet of optimum conditions with corresponding densities determined from the standard AASHTO test. The results indicate that initial moulding water content has considerable influence on the resulting structure (and aggregation), which in turn influences the soil-water characteristics. In the low suction range (i.e. 0-1500kPa), macrostructure governs the soil-water characteristics for specimens compacted with dry of optimum initial water contents and they exhibit a steeper slope. For the specimens compacted at wet of optimum, microstructure governs the soil-water characteristic behaviour. The soil-water characteristic of the specimens compacted at dry of optimum are influenced by the stress history.
