Results of field and laboratory tests are said to have indicated that presence of ballast above level of bottom of tie has little influence on quiescent load which will be carried before ballast will work out from under tie and allow it to settle, but that under repeated applications of load and particularly under jarring and vibratory loads ultimate carrying capacity of ballast is considerably increased by raising level of ballast surface to top of tie.
