Influence of geosynthetic localization in subbase was examined considering its effectiveness and mining influences. Large-scale apparatus was used to simulate horizontal unloosing strains Epsilon_r. A coefficient of lateral earth pressure K_Epsilon determined on horizontal and vertical stresses was used to compare effectiveness of geosynthetic in different height of subbase. Results for unreinforced and reinforced subbase were compared. Implementation of geosynthetic reinforcement allowed to withstand higher values of horizontal unloosing strains Epsilon_r.
