Description of ASTM-D4788 2007ASTM D4788 - 03(2007)Standard Test Method for Detecting Delaminations in Bridge Decks Using Infrared ThermographyActive Standard ASTM D4788 | Developed by Subcommittee: D04.32 Book of Standards Volume: 04.03 ASTM D4788Significance and Use This test method may be used in conjunction with other test methods in determining the general condition of a bridge deck. Areas indicated as delaminated on overlaid bridge decks may be an indication of lack of bond between the overlay and the underlying bridge deck. This test method may be used in determining specific areas of delaminations requiring repair. 1. Scope 1.1 This test method covers the determination of delaminations in portland-cement concrete bridge decks using infrared thermography. This test method is intended for use on exposed and overlaid concrete bridge decks. 1.2 A Precision and Bias statement has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes. Note 1This test method can be used on asphalt or concrete overlays as thick as 4 in. (100 mm). 1.3 This test method uses an imaging infrared scanner and video recorder, mounted on a vehicle, to detect delaminations and debonded areas on bridge decks and to record the information. The values stated in inch-pound units are to be regarded as the standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
