True triaxial testing of geogrid for high speed railways [PDF]

Transportation Geotechnics, 2019
This work describes a series of novel experimental tests to determine the potential of geogrids to confine granular layers within ballasted railway lines operating at speeds close to critical velocity. This is important because at low train speeds, vertical stresses are dominant, but when approaching critical velocity conditions, dynamic horizontal ...
