Book excerpt: "The dissertation is composed of three papers, which cover the lack of information on the specific aspects of non-destructive and destructive bridge deck assessment. In the first paper, appropriate data acquisition and processing parameters for concrete bridge deck condition assessment using ground-coupled ground penetrating radar are developed. The use of proposed parameters helps to significantly reduce acquisition and processing time, while providing engineers with reliable and detailed information on the condition of bridge deck. In the second paper, a novel approach to develop relationship between GPR data and concrete removal depth measurements collected after hydrodemolition is proposed. A linear relationship between the two is assumed, justified and corrected. Two case studies are used to verify the proposed approach. In the third paper, an integrated approach in assessing bridge deck condition is introduced. Four techniques -- visual inspection, GPR, USW, and core control -- were used to perform a bridge deck assessment. LiDAR measurement of concrete depth removal collected after hydrodemolition were used as ground truth. The advantages and disadvantages of each method are discussed. Qualitative and quantitative comparisons of data collected using non-destructive and destructive techniques are performed"--Abstract, page iv.
