However, few contributions have been made on in situ testing of these soils. This indicates the necessity for additional research work to be done to correlate predictions based on laboratory results with in situ measurements. This paper presents a research work done at 10 different sites located in desert areas at the boundaries of Cairo. 5 of these sites are known for expansive soil formations and the other 5 sites are known for collapsible soil formations. For each site standard penetration testing was done for a depth of two meters, firstly at natural dry state; and secondly after flooding by water for 48 hours. In the same time undisturbed samples were taken from open pits adjacent to borehole locations for the determination of their physical properties as well as the determination of swelling or collapse potentials using the oedometer apparatus. Relationships were then made to correlate the number of blows ( N, N' ) for the standard penetration testing at dry and wet state respectively with the parameters determined from laboratory testing. These relationships were made to test the validity of predictions based on laboratory results and to provide parameters required for the most appropriate and economical design of foundations on problematic soils.  Conference Name : GEOPROB 2005 -International Conference on Problematic Soils to be held on 23-27 May 2005 in Famagusta, N.
