For the water protection of concrete bridge decks specific asphalt pavement systems are used. These asphalt pavements have to fulfil a lot of requirements regarding different parameters (bitumen, mixtures), but so far test methods and procedures for assessing their structural resistance and functionality are missing. In a recent Swiss research project different asphalt pavement systems for bridge decks were chosen. Roller compacted asphalt and mastic asphalt for wearing and protection layers as well as waterproofing layers with polymer bitumen sheets (PBD), liquid polymer (FLK) and mastic asphalt (MA) and their system behavior was investigated using different mechanical tests. The investigation provided a ranking for the different systems and showed that the predicted system behavior given by different tests often varies for the applied test methods and investigated parameters. For example, it is interesting to, see that the rutting prediction for some systems differs and the ranking changes when using cyclic compression tests instead of rutting tests conducted with the French rutting tester.
