DRILL-LIME TREATMENT OF SHALLOW RAILWAY SUBGRADE FAILURES IN EXPANSIVE CLAYS

This report deals with a method of stabilizing roadbed by applying hydrated lime to holes drilled in the subgrade which Southern Railway has been utilizing. With some 80 locations treated, the results after a few months were encouraging. While it is too soon to evaluate permanent results, it appears that the drill-lime application may offer relief to areas having the following combination of features: 1) Expansive clays responding to lime treatment; 2) Track areas having shallow ballast sections; and 3) Shallow subgrade failures.
