ABSTRACT
Due to their technical advantages, waterproofing systems with Gussasphalt mastic asphalt, polymer-bitumen waterproofing membranes and asphaltic plug joints are widely used for bridges and tunnels in Switzerland. Experience shows that type of solution is very successful and durable if planning, selection of material quality and application are conducted professionally and with special care regarding the interaction between the different components of the system.
This article focuses firstly on the interaction between polymer-bitumen asphaltic plug joints and the adjacent pavement, especially on the de-bonding which may occur due to incorrect planning or construction. Secondly, the practical aspects of the compatibility between the mastic asphalt and the polymer-bitumen waterproofing membranes, as well as the application of mastic asphalt, are explained and discussed.
