ON THE USE OF CARDED MATERIALS AS FILTERS IN TRACK LAYING

ZUR ANWENDUNG VON FILTERVLIESMATTEN IM GLEISBAU

The CFF have for some time now been using layers of carded materials as filters on various line sections. It must however be conceded that this filtering is inadequate. In point of fact, few are the types of carded material now available on the market that can ensure complete filtering. Hence the need to define criteria taking into account both the thickness of the filtering layer and of track stress. Before reliable solutions can be put into application, measurement bases must be devised for the types of soil that may be encountered.
