Strengthening of Weak Subgrade Using Geo Nailing Technique
Keywords:Black cotton soil, California bearing ratio, Geo nailing technique, No fine concrete
Soil is naturally occurring materials that are used for the construction of all pavement layers except the surface layer of the pavement. Proper treatment of problems in soil conditions and the preparation of the foundation are extremely important to ensure a long-lasting pavement structure that does not require excessive maintenance. The current study was conducted on weak subgrade soil (black cotton soil) which is having more clay or silt content. Based on the concept of soil nailing technique, in this investigation an attempt is made to increase the CBR value and load bearing capacity of the black cotton soil by introducing geo nails. Geo nails are cone shaped friction piles made of no fines concrete which will be driven into the soil at appropriate depth and lateral spacing.
