ABSTRACT: This study presents preliminary results of swelling potential for a local unsaturated expansive soil in a large cell. The sample exhibited an initial swelling of 6% after one day of inundation and a primary swelling of 46% after 210 days (seven months). The top surface consisted of alternate crests and troughs of up to 15 mm with respect to the average soil height. The sample is expected to enter into the secondary swelling range in the coming months. A comparison with a conventional test indicated the absence of differential swelling in the later test.
RÉSUMÉ: Cette étude présente les résultats préliminaires du potentiel de gonflement d'un sol local gonflant non saturé. L'échantillon présente un gonflement initial de 6 % après un jour d'inondation et un gonflement primaire de 46 % après 210 jours (sept mois). La surface supérieure est composée de crêtes et de creux alternés avec une hauteur maximale de 15 mm par rapport à la hauteur moyenne du sol. L'échantillon devrait entrer dans la phase de gonflement secondaire dans les prochains mois. Une comparaison avec un test classique a indiqué l'absence de gonflement différentiel dans ce dernier essai
