Expansive soils mostly cause significant damage to structures such as buildings, pavements and
bridges. Therefore, the objective of this study was to quantify the improvements achieved on the
weak subgrade soil strength ...
Expansive soils have considerable volume changes, which related to the change in its moisture
content. The sudden change of the volume in the expansive soil can cause major damages to the
overlying structures such as ...
