D4580-23 – Standard Test Method Technical Guide

🔍 Overview and Scope

This standard practice, D4580-23, covers procedures for surveying concrete bridge decks to determine delamination by sounding. It is not intended for decks with asphalt overlays but may be used on those with portland cement concrete overlays, where delamination may indicate bond issues. The practice should not be used on frozen concrete and is for research and informational purposes only, not for acceptance or rejection.

Note 1 acknowledges that variable field conditions such as traffic noise, vibration, and moisture content can influence results, and additional investigation may be needed. The standard includes references to notes and footnotes for explanatory material but specifies that these are not requirements
