Abstract: The operational principle for today's bridge deck surfacings is a strong and durable bond between all layers of the pavement and the concrete structure under all loads. A strong bond helps to ensure the desired safety level against water penetration. But in use there is a strong loading of the bond by crack development in the structure or pavement and its dynamical movement. To ensure the sealing function of the bridge deck surfacing over the time its waterproofing has to show a durable crack bridging ability. With it the useful life of the bridge deck surfacing is essentially determined. To characterise the influences on a durable bond strength and crack bridging ability of waterproofings special research and tests were realised in the BAM. From the test results it is possible to detect suitable waterproofing layers and differences in durability. Tensile fatigue strength and other mechanical features seems to be special suited material characteristics to describe the crack bridging behaviour of waterproofing layers.
