In the project different products for road tunnel application are investigated by systematic long time storage in hot water using a new test procedure based on SIA V 280 standard (test no. 13) and EN 14415. The objective of this research project is to derive suitable exposure conditions and criteria for a practical testing procedure with regard to service lifetimes of up to 100 years. For that test temperature and time as well as the best suitable test medium have been investigated in a structured way. To verify the results of the new test procedure the material properties of GBR-P samples removed from older road tunnels are investigated. Based on the presented results of the still on-going research program some preliminary conclusions regarding the updating of the German regulations for road tunnel sealing systems (ZTV-ING part 5 section 5 and TL/TP KDB) are given.
