Abstract

The geotechnical properties of crushed shales from the Abakaliki Albian Awgu Coniacian and Enugu Campanian Shale Formations have been assessed to determine their suitability for use in construction projects The results indicate the Abakaliki Shale is likely to be satisfactory as a fill and embankment material although the relatively high liquid limit and plasticity index may result in some swelling of the compacted shale It is not suitable as a subbase or base course for pavements The Awgu and Enugu Shales may also serve well as fill and embankment materials although their fines fraction is higher than the recommended limits Both shales are unsuitable for use as subbase or base course unless improved The use of heavy compaction equipment is recommended wherever these shales are used in geotechnical projectsLes propriétés géotechniques de schistes concassés des formations d’Abakaliki Albien d’Awgu Coniacien et d’Enugu Campanien ont été évaluées afin de déterminer les usages possibles dans les projets de construction Les résultats indiquent que les schistes d’Abakaliki sont vraisemblablement adéquats comme matériaux de remblai bien que les valeurs de limites de liquidité et d’indices de plasticité relativement fortes puissent conduire à des phénomènes de gonflement après compactage Ils ne conviennent pas comme matériaux de souscouche ou couche de base dans les structures de chaussées Les schistes d’Awgu et d’Enugu peuvent aussi servir comme matériaux de remblai bien que leur fraction fine dépasse les limites des recommandations Ces deux types de schistes ne conviennent pas comme matériaux de souscouche ou couche de base sauf si des traitements sont envisagés L’utilisation d’équipements lourds de compactage est recommandée lorsque ces schistes sont utilisés dans des projets géotechniques
