Reinforcement of pavement subgrade using granular fill and a geosynthetic layer

Engineers are often faced with construction of pavement structures over soft and compressible subgrade. Such conditions render the structures unable to withstand required design loads and thus are susceptible to high settlements associated with excessive distress leading to pavement damage. The use of imported quality fill to improve the load-bearing capacity of the subgrade has limited benefits, which leads to the necessity of an alternative construction approach to attain the necessary strength of the soil structure. The use of geosynthetics in soil offers a better alternative to improvement of the soil's stability. This research was conducted to determine the degree of improvement of the load-bearing capacity and reduction in settlement due to geosynthetic reinforcement of a soft clay overlain by granular material.
