Substantiation of determination of strength performance of coarse-grained media by the oblique shear method

The constantly increasing loads of vehicles predetermine the search for ways to improve both design methods, technological processes and quality road construction materials. volumes open-pit coal mining require finding haul roads mines. Thus, a qualitatively new approach is needed determine strength performance coarse-grained media. In this work, it proposed granular media by oblique shear method, since today there no method advanced apparatus makes possible pre-compacted with particle size up 20-30 mm. To avoid effect keyways chaotic results, optimum clearance between upper lower holders should be 0.3 times maximum size.
