Ballasted Roof System | Ballasted EPDM

Ballast stone traps a lot of dirt, making patching difficult. Ballast stone fractures and gets sharper over time, which can puncture the membrane. Ballast stone can crush the underlying insulation, creating weak spots in the roof membrane. Over time, the stones move around, creating "Bald spots" where the system isn''t held down at all.

Discrete element modelling of scaled railway ballast under ...

 · The aim of this study is to demonstrate the use of tetrahedral clumps to model scaled railway ballast using the discrete element method (DEM). In experimental triaxial tests, the peak friction angles for scaled ballast are less sensitive to the confining pressure when compared to full-sized ballast. This is presumed to be due to the size effect on particle strength, whereby smaller particles ...
