before the last readings. A better estimate would have been possible if the
readings could be continued until 1 year after the last load increment, at least.
An attempt was made to use an alternate procedure, developed by Asaoka
(1978) for predicting consolidation and creep settlements. Although Asaoka's
procedure is generally applied for predictions in clays, the creep behavior
observed with the displacement velocity plot suggested that its use can be
extended to HRSS of the type of the Verrand Embankment.
The typical plot used in connection with Asaoka's method is displacements
at time t 2 1 versus displacements at time t. The typical shape of these curves,
upon application of a single loading increment, is a sharp rise followed by a
flatter segment, eventually ending against the reference curve ds ð t 2 1 Þ¼ ds ð t Þ:
