An experimental study on the stiffness of a lime-treated clayey soil

One of the main reasons for the difference between lime-treated soil samples prepared in the laboratory and the treated soil samples taken from the field could be the difference in aggregates size. Indeed, prior to compaction in the laboratory, the soil is usually sieved at a few millimeters and then mixed with lime. On the contrary, in the field, the dimension of clay clods may reach several centimeters before the treatment.
