Penelitian dilaksanakan di wilayah Desa Limamar yang tanahnya tersusun oleh tanah lempung kaolinit. Tanah kaolinit terendapkan diatas formasi warukin umumnya mengandung lapisan batubara. Kegiatan tambang batubara memerlukan jalan tambang.Pengumpulan data dilakukan berdasarkan hasil observasi lapangan, sampling dan uji laboratorium serta studi literatur. Data primer dikumpulkan berkait karakteri...

Clays encountered during road construction are mostly weak and result in major pavement failures due to their low California bearing ratio (CBR) high swelling potential. In this study, sustainable eco-friendly waste materials including brick dust (BDW), ground granulated blastfurnance slag (GGBS), recycled plastic (RP) glass (RG) at varying proportions of 11.75% 23.5% were used as partial repla...

The study area is located in Upper Egypt as a part of the Sohag Governorate. In this study, engineering geological properties for soil deposits three new urban areas southwestern Governorate are discussed and evaluated based on field survey boring, geotechnical experiment petrographical examination. studied covered by Quaternary Pliocene composed mainly gravely sand, silty clay, clayey silt roc...

In this research, behaviour of clayey soils under triaxial loading is studied using Neural Network. The models have been prepared to predict the stress-strain behaviour of remolded clays under undrained condition. The advantage of the model developed is that simple parameters such as physical characteristics of soils like water content, fine content, Atterberg limits and so on, are used to mode...

compost is a gradual process in nature by which organic materials are decomposed in the presence of air by microorganisms and fungi. the product is a valuable fertilizer that is used in different places even in home little gardens, so that it has signed as an unnoticed asset. with due attention to the importance of compost, its guidelines and standards should be evaluated. it is pointed and com...

The Betz theory expresses that no horizontal axis wind turbine can extract more than 16/27 (59.3%) of the kinetic energy of the wind. The factor 16/27 (0.593) is known as the Betz limit. Horizontal Axis wind turbine designers try to improve the power performance to reach the Betz limit. Modern operational wind turbines achieve at peak 75% to 80% of the Betz limit. In 1919, Albert Betz used an a...
