Review article

The paper presents the results of research on establishing the optimal cross-sectional shape of a 3d geogrid rib. in the course of research, there was studied the behavior of crushed stone particles in the array and the mechanical characteristics of the bearing base wedging were determined. The influence of flat and volumetric reinforcement on the behavior of crushed stone particles in a reinforced array was analyzed. Conclusions were drawn regarding the influence of rib geometry on the use of 3d geogrids in crushed stone base on the improving of highway operational characteristics. it has been established that the most optimal options for reinforcing road clothes are geogrids with the ratio of the sides of the cross-section of the rib 1:1 and 1:2.
