Thermal imaging of slopes and substructures
Infrared thermography is a non destructive testing method that enables large areas to be surveyed quickly, remotely and therefore, in many cases, cost effectively. It is often used to narrow the scope of an investigation by finding potential problems hidden within slopes and structures prior to further investigation using other methods. In this scoping study, the use of thermal imaging was investigated for a range of civil engineering applications to evaluate its potential. Field investigations were undertaken at a highway slope, embankment dams, a masonry arch bridge and a retaining wall. Active thermographic studies, where heat was introduced, were undertaken to detect subsurface defects in concrete, defects in concrete below a waterproofing layer, and to locate under the road heating pipes.
