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.
