Sažetak
When calculating the lateral pressure on the retaining wall, and generally, where there is contact between soil and the structure, it is necessary to know angle of soil friction on construction. This paper deals with experimental research of the friction angle of the grain materials on rigid wall, with different dominant orientations of the grains relative to the wall. Twelve series of direct shear experiments were performed with the dominant orientation of the particles of grain materials 0° and 90° with respect to the wall. Specific fill in technology method was proposed. The results showed that the difference in the angle of wall friction relative to the orientation of the grain is less than 5%. In other words, we can neglect it, and in calculations with grain materials, can use the angle of wall friction as a constant irrespective of the orientation of the layers to the retaining wall
