Résumé

Dans le but d'une utilisation en technique routière, des argiles latéritiques brésiliennes à kaolinite et gibbsite ont été expérimentalement compactées avec ou sans addition de chaux. Les transformations structurales et minéralogiques du matériau avant et après compactage sont étudiées par des méthodes pétrographiques. La stabilisation du matériau s'effectue en deux temps par une réaction à court terme, en moins d'une heure avant le compactage et par une réaction à long terme, grâce à des néoformations minérales variées (8 espèces) qui jouent le rôle de ciment. La prédominance d'aluminates de calcium semble indiquer une réactivité plus grande de la gibbsite. Les conditions de stabilité de ces phases sont discutées d'après les données de la littérature.

Abstract

With the object of using for road construction, lateritic clays from Brazil (kaolinite and gibbsite) have been experimentaly, compacted with or without lime addition. Structural and mineralogical transformation of the material before and after compaction were studied by petrographic methods. The material stabilization is making in two states by short term reaction, less than one hour, before compaction and by long term reaction thanks to various mineral neoformations (8 species) which take a part in cimentation. The predominance of calcium aluminates seems to indicate a greater reactivity of gibbsite. Stability conditions of these phases are discussed according to litterature data.
