Several master students worked on swelling soils. Intensive laboratory and field test programs were carried out by the students under my supervision. Full scale tests were performed in Wad Medani town and in Khartoum. The research resulted in provision of guidelines for the design and construction of different foundation systems on Sudanese swelling soils (piles, raft and strip foundation). Several papers were published in international conferences and local journals. Research is going on since the year 2000 to study the effect of physic-chemical properties of our soils on their swelling and shrinkage behavior. A research fund (175000 SDG) was generated from the Ministry of High Education for this research project. As a result new approach for the quantification through testing and definition of swell potential has been introduced. A research project on the shear strength of unsaturated swelling clays and its relation to matric suction was partly finished. A paper was recently presented to the 16th African Regional Conference on Soil Mechanics and Geotechnical engineering in Tunisia. - Stabilization of Dispersive Geomaterials: I was an active team member of an intensive research project that continued for 18 months at BRRI in collaboration with University of Kalsruhe in Germany for the 4 characterization and treatment of the potentially dispersive soils of Merowe dam. The research team constituted two staff members from each side. The research was requested by Dams Implementation Unit (DIU) and the International Panel of Experts of Merowe Dam for looking at means of using potentially dispersive Nile deposits as dam core material. Special equipment were availed for the project. The behavior of Nile Silt and Upper Terrace Clay deposits were thoroughly evaluated for suitably as dam core material. The soils were classified as potentially dispersive. Lime and Gypsum were studied for the treatment of dispersivity and erodibility. Intensive laboratory programs were carried out at BRRI and in Germany including scanning electron microscopy and high pressure filter tests. The high pressure filter apparatus used at BRRI was manufactured in Sudan and performed very well. The findings of this research were utilized in the design and construction of Merowe dam. The findings were published in Sudan Engineering Society Journal as well as in BRR Journal (Check publications). - Pavement Materials: The research on pavement materials is going on. One Ph.D student finished his research project on the characterization and engineering properties of the natural unbound materials in Khartoum state. The practice of mechanical and chemical stabilization of unbound materials has been critically studied. Resilient Modulus (MR) and permanent deformation (PD) tests (dynamic tests) were performed for the first time in Sudan on pavement materials from Khartoum state. The findings have been published in local journals (two papers) and international conferences (2 papers). They will help in the understanding of the causes of failure of our major pavements and also the selection of suitable materials for their design and construction. One master student worked on the effect of fines and asphalt grade on the stability and flow characteristics of hot mix asphalt using local materials. The findings were published in Building and Road Research Journal. Another master student is working on the resilient characteristics of subgrade materials from Khartoum state. He is correlating MR with unconfined strength, DCP and un-soaked CBR. He is writing his thesis. I have recently been selected reviewer for Transportation and Geotechnics Journal published by Elsevier. - Lime Stabilization of Tropical Soils: The tropical soils which lend themselves for improvement with lime in Sudan are the swelling clays and lateritic soils. Swelling soils cover more than 40% of the area of 5 Sudan. They are characterized by their very high potential for swelling and shrinkage. They are very poor subgrade for roads and cause great hazard as subgrade soil. Their improvement is vital for road design and construction. Several research projects were carried out at BRRI on lime stabilization of tropical clay soils in Brazil and Sudan. I spent one year in Brasil (1999) working on a project of using lime and waste materials to stabilize lateritic clay soils. The findings were published in ASCE (Journal of environmental Engineering). Two M.Sc. students and one Ph.D. student finished their research on lime stabilization of tropical clay soils (expansive clays and clays with mixed mineralogical composition) for use in road construction. Advanced equipment have been used and interesting new findings were reached. The technical and financial viability of using hydrated lime for the stabilization of our tropical soils have been ascertained. The reaction products of tropical clays with different mineralogical composition when mixed with lime have been identified and the effect of minerslogy on the lime-soil reaction was fully understood and defined. Papers have been published in International journals (GEOMATE & EJGE) as well as local journals (BRR and SES). 5.2 Current On-Going Research Projects M.Sc.
