TESTING OF SUBGRADE-STABILIZATION MOVES AHEAD

One of at least five different fabrics which are available for stabilizing soft ground is discussed in this article. Monsanto's Bidim is a highly permeable fabric of continuous filament polyester fibers which has been installed for tests in railroad subgrades. Since ballast must be removed, test installations have been made in conjunction with track undercutting. Claims for fabrics are that they facilitate drainage, prevent fine soil from fouling subballast and spread heavy axle loads.
