The literature have been directed to categorizing this transitional border line material into soil-like and rock-like types. Many of these types are unsaturated with a certain degree of lithification and associated with geotechnical problems. These problems are due to their tendency to volume change and mobilization of swelling or collapse. The present research aims at integrating the behavior of the material into the framework of unsaturated soil mechanics. Based on testing of 72 samples representing a wide range of soil properties, prediction charts were constructed. The proposed charts were investigated by testing 29 undisturbed samples representing a variety of transitional border line deposits and their deformations were measured. A very good agreement was found between measured and predicted values.  Conference Name : Proceedings of the International Conference “Geotechnical Challenges in Megacities” (GeoMos2010; Moscow, June 7-10, 2010)- vol. 3- pp; 1054-1060  Publishing Year : 1431 AH 2010 AD  Number Of Pages : 7  Article Type : Article  Conference Place : Moscow- Russia  Organizing Body : International society of Geotechnical Engineering  Added Date : Saturday, March 26, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email محمد عبدالقادر الصهبى El- Sohby, Mohmmed Abdelkader Investigator Doctorate msohby@hotmail.com سعيد أسامة مازن Mazen, Said Osama Researcher Doctorate Mazen_62@Yahoo.com محمود إبراهيم أبوشوك Aboushook, Mahmoud Ibrahim Researcher Doctorate profdraboushook@gmail.com Files File Name Type Description  29383.pdf pdf Differential classification at boundaries of soil and rock Back To Researches Page
