to have a special design. Cf. in this regard fig. 8 in Section 2. In order to avoid water flows and leaks, it is recommended arranging a drainage channel to be backfilled with chippings (no fines) beneath the longitudinal joint (lining separation) which drains into the frost-resistant layer or into the layer consisting of frost-proof material. In order to reduce strains owing to varying movements and to provide additional sealing, it is sensible to apply welded bitumen sheeting to the concrete edge. The joint design shall correspond to the thickness of the basecourse according to the construction; the width of the joint shall be at least 10 mm. Chamfering of the concrete edge is not absolutely necessary. b) Connections to sett pavements When joining sett pavements to different carriageway surfaces, the connecting joint is constructed to the width of the paving joint. Building materials a) Products standardised across Europe: filling compounds must be adapted to the respective intended purpose. They must comply with European standards, the requirements of which are incorporated in the Technical terms of delivery for joint filling compounds in traffic areas. Hot applied joint sealants Cold applied joint sealants (permissible total deformation: 25%) Joint seals Primers The use of type F1 and F2 hot applied joint sealants as per DIN EN 14188-1 is not permissible. If a primer is envisaged for a joint filling system, the instructions concerning execution from the system provider must be observed. b) Products that are not regulated across Europe: Hot applied paving and rail joint sealants and crevice sealers, cold applied joint sealants (permissible total deformation: 35%), bituminous water stops and appropriate primers must satisfy the “Technical terms of delivery for joint filling compounds in traffic areas”.
