Effect of Adding Mixture of Sand Dunes and Emulsified Asphalt on Engineering Properties of Gypseous Soil

This research includes an examination of direct shear to find cohesion gypsum soil (C) and the angle of friction (9) internal to that soil and also conducted screening collapse to find the amount of collapse (Cp) and examination of endurance Californian rate (CBR TEST) in addition to the tests Mark Forums Read this soil. Where that all these tests were conducted on soils is confused and soil confused untreated soil confused address mixture (2%, 3%), (2% 0.6%), (2% 0.9%), (2 .12%), (4 % 0.3%), (4%, 0.6%), (4%, 0.9%), (4%, 0.12%), (6% 0.3%), (6%, 6%), (6%, 9%), (6%.12%) (8% 0.3%), (8%, 6%), (8% 0.9%), (8% 0.12%) {emulsion asphalt and sand dunes on respectively. The results showed that the strength of cohesion Azdadh worth about (43%) at the optimum proportions of emulsion asphalt and sand dunes that are (6% emulsion asphalt 0.9% sand dunes mixture treatment) compared to the untreated soil confused. The value of the friction angle also increased its value by 33% at the optimum proportions of the mixture of asphalt emulsion and sand dunes that are (6% asphalt emulsion 0.12% sand dunes treatment) compared to the untreated soil confused. As for the breakdown in the soil in the gypsum soil used in research has decreased by 59% when using the optimal ratios of emulsified asphalt and sand dunes mixture (6% asphalt emulsion 0.12% sand dunes) compared to the untreated soil confused. As well as increased endurance ratio Californian by (27%) for a breakthrough at 2.5 mm and also this figure increased by 19% for a breakthrough at 5 mm and when treatment for optimization of emulsion asphalt and sand dunes mixture (6% Asphalt Emulsion 0.12% sand dunes) compared to soil Jbsh confused untreated .
