Stress-strain behaviour of some compacted laterite soils from north-east Brazil
Abstract Laterite soils in compacted from are widely used as fills and road construction materials in countries within the tropics. Certain unusual engineering characteristics have been established for some of them and these have been the subject of previous investigations. The present work concerns the examination of one such unusual engineering characteristic. The stress-strain behaviour of three compacted laterite soils from North-East Brazil have been examined using the shear-box machine. The investigation reveals the existence of a “collapse behaviour” previously identified only in undisturbed laterite soils. The “collapse behaviour” has been interpreted in terms of degradable soil particles which comminute under load. The comminution occurs before the ultimate failure of the soil body is reached.
