TESTING OF SUBGRADE STABILIZATION FABRICS MOVES AHEAD - 2

This is the second in a series of articles dealing with fabric for stabilizing soft roadbeds. Mirafi 140 is a nonwoven material composed of man-made fibers randomly laid into a continuous web and fuse bonded. In railroad applications Mirafi is engineered for use over soft subgrades. It can serve to separate ballast from subgrade, as a filter preventing the migration of moist soil fines into ballast and as a tensile reinforcement which also confines ballast by frictional resistance at the ballast/subgrade interface.
