Collapsible behaviour of soil is considered as one of the major problems in the stability of roadway embankment, the lack of cohesion between soil particles and its sensitivity to the change of moisture content are reasons for such problem. Creation of such cohesion may be achieved by implementation of liquid asphalt and introduction of Nano additives. In this work, silica fumes, fly ash and lime have been implemented with the aid of asphalt emulsion to improve the unconfined compressive strength of the collapsible soil. Specimens of 38 mm in diameter and 76 mm height have been prepared with various percentages of each type of Nano additive and fluid content. Specimens were subjected to unconfined compressive strength determination at dry and absorbed test conditions. It was concluded that the unconfined compressive strength increases by (13-25) folds after stabilization with asphalt emulsion at dry test condition. The implementation of lime shows that the cohesive strength is increased by a range of (93-517)% for absorbed condition, while it decreased by a range of (50-31)% at dry test conditions. When 5% silica fumes was introduced, the compressive strength increased by 9.2% in dry test condition while it decreases in a range of (31.5-63.8)% for other percentages. When fly ash class F was introduced, the reduction in the strength was in the range of (100-120)% for various fly ash content at dry test condition.
