The research objectives are to use recent ASTER satellite imageries with the aid of field
samples to map different swelling clay minerals and compare between the different sensors accuracy
in locating them within the buffer zone. Certain engineering measures should be considered to
enable construction over these types of swelling soils. The results confirmed the presence of montmorillonite
in this buffer zone and in the 5 km buffer around the road which represents a hazard
especially for the future planned projects within this area.
