MEASUREMENT OF AUTOGENOUS HEALING IN STABILIZED SOILS

Autogenous healing has been known to occur in lime and cement stabilized soils. The extent of, and factors affecting its occurrence are however not adequately documented in the literature. This paper describes a laboratory study of this property using a lateritic soil, lime, and cement. The stress/strain properties of the stabilized soil specimens were measured after periods of initial curing. The tested specimens were further cured for various periods and a second stress/strain measurement undertaken. The autogenous healing was then computed. From the results of the study it was found that short initial curing periods and long curing periods after flawing enhanced the healing process. It is inferred from the study that beyond seven days curing a lime or cement stabilized base over stressed to failure will not heal up but deteriorate. Light traffic may be allowed however, within seven days of laying a lime or cement stabilized base without danger of any flaws being healed up later. (TRRL)
