SEALING CONNECTIONS AT BUILT-IN UNITS IN BRIDGES

ABDICHTUNGSANSCHLUESSE BEI EINBAUTEILEN AUF BRUECKEN

Based on the information available in the governing DIN standards and VOB specifications, the advantages and disadvantages of glued or loose or fixed gaskets including bituminous and plastic waterproofing courses are treated. The conditions or requirements for glued gaskets, clamped gaskets or loose and fixed gaskets are given (the liability, minimum dimensions, possibilities of repair, safe dewatering, long term impermeability under static, dynamic and thermal stresses). Loose and fixed gaskets should generally be used, where static force effects are to be expected over the pavement, small gasket surfaces cannot be produced safely and the ends of the waterproofing courses must have a secure protection against the possibility of water flowing back along the waterproofing course surface. Glued gaskets may be used when a loose gasket hinders the drainage at the surface and where an adequate gasket width makes possible a two layer junction of the sheet-type material in a back-packing operation. The additional costs for a safe junction of a waterproofing course to eliminate penetration is given for four actual projects. Finally, the calculation of the traction moment of a glued structure and of a bitumen waterproofing course is explained. (TRRL)
