Design Characteristics of Road Structure Reinforced with Cell Geosynthetic Materials with Account of Dynamic Load Impact

Modern highways are exposed to intensive transport loads, which require strengthening of the road structure and considering the dynamic load action on design characteristics of materials. The studies define quantitative changes of strength and strain characteristics of the road structure materials depending on amplitude of oscillations under dynamic loads. Subject to the road structure design and materials used, the strength of soil subgrade, for example, can decrease under vibration by 20-30% as compared to the design value defined without taking the vibration factor into account. The use of cell geosynthetic materials in the road structure allows improving its stress strain behaviour within the range of 5% - 15%. To that end, layers of less stiff material should not be placed above stiff layers reinforced with cell geosynthetic materials.
