. In the paper results from experimental tests and state of the art of the GPR technique are presented. Tests were done with the use of SIR-20 GPR system with two antennas 1.6 GHz and 2.6 GHz. The results indicated possible application fields of this technique during condition assessment process of the concrete and prestressed bridges. Particular attention was focused on the preparation of guidelines on how to use this technique in practice. In the paper all stages of testing and data interpretation were thoroughly described and explained.

W pracy przedstawiono stan wiedzy oraz wyniki badań doświadczalnych konstrukcji żelbetowych i z betonu sprężonego metodą georadarową. Badania przeprowadzono metodą odbiciową (refleksyjną) za pomocą systemu radarowego SIR-20 wraz z zestawem anten o częstotliwościach centralnych 1,6 GHz oraz 2,6 GHz. Wyniki wskazały możliwe obszary zastoso-wań badań georadarowych przy ocenie stanu technicznego obiek-tów mostowych z żelbetu oraz betonu sprężonego. Szczególną uwagę poświęcono na przedstawienie wytycznych, jak tę technikę zastosować w praktyce. Podano zalecenia dotyczące wszystkich etapów badania z wykorzystaniem georadaru, w tym w zakresie planowania, ograniczeń i wymagań praktycznych, warunków do-stępu do konstrukcji oraz właściwych procedur zbierania i analizy danych.
