Studies on Engineering Performance of Geogrid Reinforced Soft Subgrade

Transportation Research Procedia, 2016
Abstract One of the preferred materials for construction of road embankments on soft subgrade soils being coarse grained soils. During the recent past utilization of geosynthetics has been increased to improve bearing resistance of weaker subgrades. Previous researches addressed the problems due to soft subgrade in several ways and provided solutions
