ACE products can play various roles in railway application. For instance, ACETex®
can separate ballast and subgrade to decrease upward pumping of subgrade fine aggregate which may pollute the ballast and lower its bearing capacity. ACEGrid®
can help decrease the occurrence of ballast sinking into soft subgrade. Moreover, ACEDrain®
can be used to improve the drainage of subbase and above mentioned situations.
High tensile strength ACEGrid® and ACETex® or ACECell® with confinement ability can be used in unstable subgrade to increase its bearing capacity.
