Akoto, B.K. A., 1986. The effect of repeated loading on the ultimate unconfined compressive strength of a lime-stabilized laterite. Eng. Geol., 23: 125--135.

The effect of repeated loading on the unconfined compressive strength (U.C.S.) of both natural and lime-stabilized laterite has been examined. The general observation was that subjecting the material to repeated loading increases the ultimate unconfined compressive strength. For the same lime content and curing period, samples subjected to dynamic tensile load applications have residual unconfined compressive strengths greater than similar samples subjected to compressive dynamic loading before the determination of the residual unconfined compressive strength. Samples cured for seven days have an unconfined compressive strength about 80% of those cured for 28 days, but after subjecting samples cured for seven days to repeated loading, these had ultimate unconfined compressive strengths greater than the 28 days samples subjected also to repeated loading.

Factors responsible for these changes in strength have been examined.
