Assessment of Structural Integrity for a Concrete Runway by Seismic Techniques

Abstract:

Article Preview

Concrete runways are subject to material deterioration or structural problems, which lead to surface cracks and scaling of a concrete pavement. In this study, seismic techniques including the SASW method, the impact-echo method and the impulse-response method were integrated into a systematic nondestructive approach, which is designed for the assessment of structural integrity of concrete runway pavements. Numerical simulation of the employed seismic methods was performed to verify the validity. For feasibility, the integrated approach was applied to a concrete runway which has surface cracks at pavement segments not subject to airplane loading. The approach verified that the surface cracks were attributed to reduced subgrade stiffness, which may not be detected by conventional pavement tests. The validity of the integrated approach was also proven in lieu of forensic engineering for concrete runway pavements.
