A042 Z-99 Assessment of the quality of radar results on Abstract Summary 1 bridge decks JOHANNES HUGENSCHMIDT EMPA Ueberlandstrasse 129 8600 Dübendorf Switzerland [email protected] Ground-Penetrating-Radar has become an important tool for non-destructive testing of concrete bridges. The evalution of the quality of radar results is in most cases restricted to very few points on real objects or to laboratory experiments. In recent years Empa had the opportunity to complete several projects aiming at the evaluation of radar results on concrete bridges. This paper presents an overview of the results giving a quantitative estimate of the quality of radar results. Introduction
