Three-Dimensional Visualization and Presentation of Bridge Deck Condition Based on Multiple NDE Data
AbstractA method is developed for presentation of a concrete bridge deck condition assessed by multiple nondestructive evaluation (NDE) technologies using a three-dimensional (3D) visualization program. Four types of NDE data are merged and visualized in the program: (1) impact echo for mapping and describing the severity level of concrete delamination; (2) ultrasonic surface wave for concrete quality (elastic modulus) assessment; (3) electrical resistivity for estimating the corrosion rate of steel reinforcement; and (4) high-resolution imaging of a bridge deck surface for documenting signs of deterioration, previous repairs, and surface wear. The developed visualization platform integrates the four NDE data types and visualizes in a 3D space in a very intuitive way. As such, the program assists in understanding of the complex relationships of bridge deck conditions assessed by multiple NDE techniques. In addition, a correlation between external (surface cracks, wear, and previous repairs) and internal deterioration (delamination, concrete degradation, and corrosion) can be studied and visually identified utilizing the developed 3D visualization program.
