Hot-dip galvanized composite dowel strips

This paper presents additional potential for the future economic development of composite dowel strips by using the durable and long‐lasting corrosion protection of hot‐dip galvanization. Based on the completed FOSTA research project P835 [5] on the use of hot‐dip galvanizing for steel and composite bridge construction, the range of applications for hot‐dip galvanizing will be transferred to composite dowel strips in composite bridges. Following a brief summary of the most important results of the previous project, where the corrosion protection duration and the influence of hot‐dip galvanizing on the fatigue behaviour of steel were examined, the objectives and planned studies of the new research project will be presented. The currently ongoing FOSTA research project P1042 [8] was initiated by RWTH Aachen University and TU Dortmund University. The results should allow the safe use of hot‐dip galvanized composite dowel strips in conjunction with cyclic loads.
