In this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from SM to GM on behavior of sandy soil. In this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 KPa were carried out in ...

This study introduced at first the background of numerous highway widening projects that have been developed in recent years in China. Using a large ground settlement simulator and a fiber Bragg grating (FBG) strain sensor network system, a large-scale model test, with a similarity ratio of 1:2, was performed to analyze the influence of differential settlement between new and old subgrades on p...

Modular Geogrid Reinforced Soil (GRS) retaining walls, as flexible structures, usually have a certain deformation capacity. However, the damage of facing panels will directly affect durability performance wall and pose threat to safety operation road related facilities. In order study influence different load factors on mode failure characteristics wall, an indoor large-scale model test was car...

Roads are subjected to vehicle traffics with different loads and velocities. Geogrid reinforcement is of the best methods for road improvement due to the ease of construction, delay in damage development and financial efficiency. This study evaluates pavement response under different loads and velocities, before and after geogrid reinforcement. A finite element software (ABAQUS) is used for num...
