Ice and snow accretions on bridges pose a hazard for motorists and pedestrians, as shedding accretions can have a significant mass associated with them. Various technologies have been tested on numerous bridges in an attempt to prevent accretion build-up or help mitigate the effects of the falling snow or ice on the traffic below. Most have been found to have problems with durability and cost-effectiveness though. In this paper, we present preliminary test results from ice shedding tests that have been performed on innovative cable surface modifications in the DTU/Force Technology Climatic Wind Tunnel (CWT) in Lyngby, Denmark. It is shown that contrary to the ice shedding of contemporary cable surfaces, the innovative surfaces retain the ice longer during the melting process, reducing the shedding ice mass and particle size, thus reducing the risk associated with the shedding ice. |
