layer 5: green lumps of black basalt clay-dust filling. stone block structure, exists as the foundation stone of 20-50 cm size. scattered over the area. This layer of weathered basalt boulder format, distribution dissimilar classes focus lying areas. distributed heterogeneous classes in the entire route, the depth of the soil layer from 0.6-2.6 m average, sections separate from g2 - g5 rather shallow, g3-g4 special. therefore in the construction process should redefine exactly compressive strength, to select construction solutions
