Durability of JGT

There have been rigorous research and studies with JGT in several engineering research institutes in India and Abroad. The following inferences are note-worthy  

  • Loss of strength of JGT after a year is NOT a technical disadvantage– because by that time, JGT provides a self-sustaining sub-grade for most soils  (Ramaswamy & Aziz-1989)  

  • The gain in strength of the sub-grade compensates the loss of strength of JGT within the same time frame (IBID & JU 2005) 

  • With the passage of time dependence of soil on JGT for stability decreases
