SUCTION - MOISTURE CONTENT - STRENGTH AND TIME RELATIONSHIPS OF A LATERITIC SOIL

Experiments were carried out to examine relationships between the soil suction, water content, time and unconfined compressive strength for compacted "red earth" of South- western Australia. The suction of moderately compacted samples with initial (or moulding) moisture content of 12 per cent increased from zero to 3.5 mpa (or 35 bars) after a drying period of 5 days. This value increased to about 20 mpa (or 200 bars) after 14 days. As the compacted soil specimens dried out from 12 per cent to 6 per cent moisture content, the unconfined compressive strength correspondingly increased from 16 kpa to a peak of about 300 kpa. Below 6 per cent moisture content the strength decreased sharply. Results from the present study and those reported by other investigators were used for establishing general relationships between suction, unconfined compressive strength and moisture content.
