PROBLEMS OF THE SEALING OF BRIDGE STRUCTURES

PROBLEME DER BAUWERKSABDICTHTUNG VON STRASSENBRUECKEN

The increasing use of lighter prestressed concrete, the disappearance of previously standard protective layers for the concrete carriageway slab and the increasing use of thin bituminous surfaces call for special requirements as regards sealing. The following forms are common at the present time: mastic sealing with guss asphalt surfacing, metal strip sealing with guss asphalt and metal strip sealing with asphaltic concrete surfacing. The guss asphalt requires A steam pressure relieving layer to prevent blistering and must remain stable and free from cracks at all temperatures. Various steam pressure relieving layers such as glass wool, oiled paper, and crude cardboard and the problems arising during construction are described. Guss asphalt is preferred to asphalt concrete and mastic to metal strip which has to be renewed every time the asphalt is renewed. The best solutions to these problems are thought not yet to have been discovered. /TRRL/
