Abstract
The purpose of the conducted model tests was to study the possibility of using a number of design solutions with geosynthetic materials to increase the bearing capacity and reduce the deformability of the sub-base, as well as to evaluate the effectiveness of their use. Small-scale modeling tests were conducted to investigate the stress–strains behavior of embankment reinforced in the upper part with geosynthetics. A series of model experiments have shown that an increase in the number of geosynthetic layers does not significantly effect on the roadbed bearing capacity. Reinforcement in a single layer is sufficient if the geosynthetic has required strength.
