CDM designs and manufactures resilient railpads and railstrips to meet any performance requirements. Following are the standard basic types:
The CDM-SRP, or simple railpad is placed immediately under the rail.
1 CDM-SRP reduces vibrations generated by trams, trains, underground and cranes
2 Isolation improvements between 3 and 6 dBV
3 CDM-SRP can be designed to fit any rail type and fixing method
4 Easy to install under existing and new-built tracks
5 CDM-SRP increases the life of both rail and sleeper
The CDM-DPHI is a double flapped railpad. The flaps act as a sound–stop between railfoot and fastener and add damping, thus limiting the noise radiating length of the rail.
Extra advantages (with respect to CDM-SRP):
1 Improvements of up to 8dBV (insertion loss)
2 Reduction of reradiated noise
3 The CDM-DPHI railpad can be custommade to satisfy project requirements
The CDM-SRS or simple railstrip provides a continuous support for the rail, thereby resulting in significant reductions of the reradiated noise and reducing rail corrugation effects.
