In many sites on Egypt desert roads collapsible soils is broadly classified as a problematic soils containing silty fine sand which is cemented
with low density and low degree of saturation which is susceptible to a large
and sudden reduction in their volume upon
inundation, with or without vibration in its stress. Four sites have been
studied for new urban, roads and industry work sits, related to increase in natural water
content. These soils go through radical rearrangement of
their particles, causing sudden changes in the stress-deformation behavior
which cause differential settlement of foundation and roads.
This change in volume can lead to foundation failures and
worth of damages under ground public facilities and infrastructure. In this
study, the search program
