SMART‐DECK: Multifunctional carbon‐reinforced concrete interlayer for bridges

Abstract: The service life of bridges is often threatened by an insufficient shear force capacity in the transverse direction as well as by leakages in the sealing layer, which leads to chloride ingress and therefore corrosion damages. To prevent expensive repair work and traffic obstructions, a thin, multifunctional interlayer of textile‐reinforced concrete called SMART‐DECK was developed. This interlayer provides three functions: A full‐surface moisture monitoring in real‐time, a preventive cathodic corrosion protection, and an increase of the shear force capacity. The operator of the bridge is able to monitor the condition of the sealer in real‐time. The relevant data are transmitted via the internet and show the condition of the sealer in a simple color scheme. If leakage occurs, the cathodic corrosion protection can be switched on to protect the reinforcement from corrosion damages. The renewing of the damaged bridge deck sealing has not to be carried out immediately but can be postponed over years, for example, to periods with little traffic. In this paper, the scientific approach for the realization of the system is presented, beginning with laboratory pretests on the materials and numerical simulations. The results are used to test the functions of the system in the laboratory and later on two demonstrators. An outlook will present the next research questions.
