Pavement design on weak subgrade soils is to a certain extent challengeable and challenging for transportation and geotechnical engineers. Weak soil is vastly compressible clayey soils so the life of the pavements is less and effect of the weakening of the paved or unpaved surface. The development of such soil are substitutes such as replacement and excavation of unsuitable soils, compaction, Mechanical and chemical stabilization, Pre-compression and reinforcement of soil, etc., are used typically at such locations. During the recent historical utilization of reinforcement of soil by various methods has been increased to progress the strength properties and bearing capacity of poor subgrades. Field signals indicate that geosynthetic reinforcements will expand pavement performance. From this, the employment of various geosynthetics to pavement surface is testified by several researchers. Geosynthetics has numerous applications such as separation, reinforcement, filtration, drainage, and containment, etc. This paper targets to study the conclusions from various studies on weak subgrade soils using reinforcement.
