Civil Structural Health Monitoring Workshop. Berlin. Germany. 2012. Report. For a good construction, safe operation and timely maintenance of any bridge structure, a comprehensive structural evaluation becomes necessary. For this purpose, any kind of destructive testing is highly undesirable. Non-destructive testing and evaluation (NDT&E) methods provide an ideal means for a quick testing and a comprehensive evaluation of different parameters related to the strength, durability and overall structural integrity of concrete bridges. Some of these parameters are the elastic modulus/ in-situ compressive strength, uniformity and homogeneity of concrete, presence of cracks, voids and other imperfections, identification of reinforcement profile, cover and diameter, etc. This paper presents the NDT&E of Indian Railways Road bridges. The various NDT&E methods utilized are presented, and the findings are mutually compared to highlight the effectiveness of a particular method in a specific situation or for a specific purpose.
