What is Nondestructive evaluation (NDE)?
Nondestructive evaluation (NDE) encompasses several diagnostic techniques and tools used to examine the condition and structural characteristics of infrastructure.
Like a doctor may use X-rays or MRIs to detect broken bones or tumors, infrastructure professionals use NDE to see what is inside and below roads, bridges, and other infrastructure to gauge infrastructure “health.” NDE can spot potential issues before they are visible on the surface, so preventative measures can be taken before small problems become big ones.
NDE is used to examine entire structures or elements of structures and evaluate their material characteristics, reveal the presence of flaws, and ensure their quality and soundness. NDE also is essential in collecting condition data for infrastructure management systems.
NDE tools quantitatively measure and assess materials and structures by probing mechanical, electrical, thermal, optical, or other physical or chemical properties. Some of these technologies include ground-penetrating radar, infrared thermography, and ultrasonics.
NDE testing doesn’t compromise the integrity of a structure or otherwise detract from its future usefulness since the examined material or structure is left intact. It also means less disruption in service for drivers on our roads, bridges, and tunnels.
