Geotechnical properties of some residual micaceous soils in the Kumasi Metropolitan area (Ghana)

  • E. M. Frempong


Micaceous soils derived from granites, granitic gneisses and phyllites within the Kumasi Metropolitan Area have been used in road construction. The mica flakes are normally silt—and sand-sized but sizes greater than these are not uncommon.

The texture, consistency limits, compaction characteristics and California Bearing Ratio of some of these soils have been examined.

Based on these results appropriate recommendations have been made with a view to raising the standard of these materials to meet highway specifications when in service.

Propriétés géotechniques de quelques sols résiduels micacés dans la zone Urbaine de Kumasi (Ghana)


Des sols micacés dérivant de granites, de gneiss granitisés et de phyllites ont été utilisés en construction routière dans la zone urbaine de Kumasi, Ghana. Les lamelles de micas sont de la dimension des silts ou des sables et peuvent même être plus grosses.

Les données concernant la texture, la consistance et le C.B.R. ont été réunies.

Des recommandations fondées sur les résultats obtenus ont été faites, visant à améliorer les caractéristiques de ces matériaux afin qu'ils puissent satisfaire aux spécifications routières.
