New methods of subgrade stabilization are devised which take into consideration traffic loading, moisture within ballast and subgrade, and physical and physicochemical properties of subgrade soil; study included laboratory experiments on chemically stabilized specimens; durability tests on various synthetic resin films laid with sand beneath ballast and repeatedly loaded with mechanical vibrator mounted on full-size model track, and application of stabilization methods to actual tracks for prevention of mud pumping and various field investigations; methods tried on soft subgrades of Japanese National Railroads.
