a research program was conducted on different clay-bearing rocks selected from the ilam, sarpol-e zahab and tajarak regions (iran) to predict their slaking characteristics. the new durability apparatus (nested mesh drums) separates disintegrated particles varying from > 25.4 to < 2 mm as the drums were rotated. on the basis of the particle size distribution, the disintegration ratio (dr) was us...

CBR (California Bearing Ratio) value is usually used to determine the bearing capacity of a soil type. Soil conditions with low are often found in clay types. There several ways increase clay, one which by adding palm bunch ash. In this research, an analysis changes addition 5%, 7.5%, and 10% oil The results showed that largest was obtained at ash, 7.493%.

Metodologi dalam penelitian ini adalah melakukan serangkaian pengujian karakteristik tanah kemudian merancang komposisi campuran Kompaksi (Proctor Standard) untuk mendapatkan nilai kadar air optimum, Pengujian California Bearing Ratio (Unsoaked Design CBR dan Soaked CBR) daya dukung tanah.Hasil dari menunjukkan bahwa memenuhi sebagai lempung. Dari standard pada titik 1 2 dengan variasi 0%, 2,5%...
