The CDM-BAM-C is a Continuous Mat Ballast Mat which is specifically designed for reducing the vibrations, caused by rolling stock (trams and trains). The CDM-BAM-C is installed at foundation level and on the vertical surfaces of the ballast pit. The system provides a high performance massspring-mass system, resulting in low resonant frequencies and high isolation efficiency.
Advantages:
1 The CDM-BAM-C system provides a high level of vibration isolation: considerable insertion losses are achieved (see graph below)
2 Straightforward installation
3 The CDM-BAM-C system can be designed to site specific characteristics and performance requirements

system description:
The CDM-BAM-C system consists of two components:
1 A continuous elastomer mat
2 A protection mat on top
(Usually an identical ballast mat is used to treat the vertical sides of the ballast pit)
