Theoretical background of hardening the layers of rubble rocks in forest road pavements reinforcement of their geocell volume
This article describes the technology of hardening layers of crushed stone road forest road construction geocell reinforcement of their volume in order to reduce deformability-shear processes and static loads on the lower layers of the underlying subgrade and forest roads. The shear resistance of bulk materials - it is their resistance to friction with the angle of internal friction φ is directly proportional to normal pressure σ<sub>n</sub> is Coulomb ' s law. However, during the compression of the bulk material layer, a «total value of clutch c », which consists of a rigid structural coupling, fracture and irreversible adhesion plastic. Volumetric geocell layer in road is considered as material tensile horizontal wall and compressing it in the vertical plane. When the shear layer of gravel packed bulk geocell reinforced, limiting resistance in a large range of compressive pressures and stressed conditions (tensile, shear, compression) describe envelope circles limiting stresses, which is close to the curvilinear relation. In a pilot study determined the nature of change the horizontal shift and vertical crush pellet mixtures structural pavement layers. The study of deformation processes System gravel-geocell performed on various fractions of gravel samples under the action of the vertical load on the hard round stamp with limited lateral and axial movement of the material. Data are processed using mathematical statistics method with a high degree of reliability. Analysis of the data shows the positive impact of volume geocell almost all mixtures of rubble solid rock in terms of m, t, j, and Z.
