Conference on highway engineering in Africa Addis Ababa April 1974: use of local lime in stabilisation for road bases

Abstract

A locally produced lime manufactured by burning lime atone has been used to stabilize a micaceous sandy clay gravel for use in the construction of the base of a trunk road. In a laboratory trial, the gain in strength of the soils stabilized with imported quick lime was compared with the gain in strength produced by the local lime. It is concluded that lime which can be produced locally in this way can be successfully used in improving the qualities of gravels containing higher percentages of clay and having higher plasticity index than the specifications allow.
