Abstract
Bridge deck deterioration includes delamination, corrosion of rebars, vertical cracking and concrete degradation. Ground Penetrating Radar based inspection technique was used for mapping bridge deck in order to monitor the health of this vital structure. Beginning from the 1970‘s, research has focused on identification of bridge deck deterioration which causes severe deficiencies by reducing seriously strength. The main purpose of this work was to review the literature existing in the field of bridge deck diagnosis by means of Ground Penetrating Radar. This enabled to survey detailed evolution of this technique, to understand the effects of key intervening parameters and to determine the kind of material disorders that this device could be used for. Bridge deck condition assessment can then be performed more successfully, based on the huge progress experienced by this particular method of inspection.
Highlights
Bridges are vital infrastructures for transportation activity
The Ground penetrating Radar (GPR) device works by transmitting an electromagnetic energy pulse of short duration into the surface and recording reflections that occur at interfaces of materials having different dielectric properties
In the late 1980’s and early 1990’s, most of applications of GPR that were dedicated to detection of deteriorated areas in bridge decks [18,19,20,21,22,23,24,25,26,27]
Summary
Bridges are vital infrastructures for transportation activity. They require recurring maintenance and repair which can result expensive. The common method used for the assessment of bridge deck condition is based on the attenuation of the reflected waves. The GPR device works by transmitting an electromagnetic energy pulse of short duration into the surface and recording reflections that occur at interfaces of materials having different dielectric properties.
