SOIL SUCTION IN EMBANKMENTS OF EXPANSIVE CLAY

Three case records are presented of road embankments in which soil suction profiles were measured. The three case records consider: (i) the long-term behaviour of an expansive basaltic clay embankment; (ii) the selection of fill materials to be used for a reinforced earth embankment incorporating basaltic clays and (iii) the effect of tree roots on embankments. Soil suction profiles were used to: (i) monitor the long-term moisture conditions in the embankment; (ii) validate the choice of fill materials for the reinforced earth embankment and (iii) measure the extend of drying due to tree roots. The long-term soil suction values measured in the high embankments of expansive clay were found to differ from the expected equilibrium value. (A) For the covering abstract see IRRD 881647.
