Title: swelling behaviour and strength characteristics of expansive soils
Author: Mohamed, Magdi
Abstract: This paper is concerned with the study of swelling behaviour and strength characteristics of expansive soils in order to develop new design charts. Expansive soil samples with high plasticity have been compacted at a wide range of water content and different dry densities. A new characterisation concept was developed. This is called the soil siait factor which was developed for the initial and soaking stale. The initial stale factor is a conibinatirm of the dry density., water content and void reran while the soaking state factor is a combination of the saturated dry density, saturated water content and amount of svitiling during the soaking period. On basis of this concept. characterisation charts for swelling and initial state behaviour as well as strength and initial state behaviour were developed. The use of these charts In pavement design, evaluation and field compaction annual on expansive soil areas is demonstrated.
