RISApplication of Impact Resonance C-Scan Stack Images to Evaluate Bridge Deck Conditions
Publisher: American Society of Civil Engineers
Abstract: This study presents a practical approach for imaging concrete pavement and bridge deck slabs for the presence of delamination defects. Air-coupled impact resonance (impact-echo) test data are presented as a fused image by ...
Improved Interpretation of Vibration Responses from Concrete Delamination Defects Using Air-Coupled Impact Resonance Tests
Publisher: American Society of Civil Engineers
Abstract: The deteriorating national infrastructure demands improved nondestructive evaluation (NDE) and structural health monitoring methods for existing concrete structures. Vibration resonance tests offer an efficient NDE method ...
Nondestructive Bridge Deck Testing with Air-Coupled Impact-Echo and Infrared Thermography
Publisher: American Society of Civil Engineers
Abstract: Two different nondestructive test (NDT) methods, air-coupled impact-echo (IE) and infrared (IR) thermography are evaluated on a full-scale simulated reinforced concrete bridge deck containing simulated delamination and ...
Comparison of NDT Methods for Assessment of a Concrete Bridge Deck
Publisher: American Society of Civil Engineers
Abstract: The field application of three different nondestructive tests (NDTs)—air-coupled impact echo (IE), infrared (IR) thermography, and sounding (chain drag)—are evaluated in this paper, where an actual in-service concrete ...
