Cílem projektu je ověření potenciálu vícekanálového georadaru (GPR), jako nedestruktivního diagnostického nástroje, při identifikaci vad a poruch vozovek a mostních konstrukcí. Projekt bude zaměřen na navržení a praktické ověření zkušebního postupu pro: detekci dutin pod krytem nevyztužených tuhých vozovek, detekci nadměrného obsahu vody v konstrukčních vrstvách vozovek, detekci a stanovení hloubky trhlin v krytu vozovky a detekci poruch mostních konstrukcí.

Description in English
The main aim of the project is a verification of potential of multichannel ground penetrating radar (GPR) as a non-destructive tool for detection of road and bridge defects. Project is focused on design and practical verification of test procedure for detection of voids under roadbase of rigid pavements (URC), detection of excessive amount of water in structural layers of pavements, determination of crack depth in road bituminous layers and detection of bridge defects.
