SPECIFICATION
APPLICATIONS & BENEFITS
THE VIBRATION ISOLATION PERFORMANCES CAN BE TUNED BY MODIFYING:
• Mitigationofvibrationtransmission,generatedbyrollingstock,into neighboring environments
• Reductionsof15dB(v)andupto25dB(v)(ofrecordedvibrationlevels)arepossible as a function of mat stiffness and slab properties
• Insulationperformancecanbetunedbyeithermodifyingthestiffnessofthemat or the properties of the slab
• CDM-FSMiscompatiblewithalltypesofrailandtracksystems
• Straightforwardinstallation
CDM-FSM (Floating Slab Mat) is a continuous resilient mat used in Floating Slab Track vibration insulation systems. The system is based on the principle of a mass-spring system; where the mass of a concrete slab is elastically supported by a continuous elastomeric material.
