Roman Bridge of Lugo (object state)

A condition of an object at a particular time, reflecting the object's ability to fulfil it's requirements.

Object state
Summary
:
Two longitudinal parallel profiles in opposite directions along the bridge, each 122 m in length, were collected using a RAMAC/GPR system from MALÅ Geoscience with 250 and 500 MHz shielded antennas. Data acquisition was based on constant distance intervals following the common offset mode, and the survey parameters previously selected. Later GPR processing filters were employed in order to reduce clutter or any unwanted noise in the raw-data. The geometry, condition and size of this reflector allow to conclude the original double slope profile as well as the response of the transversal reinforcements and the existence of masonry and filling materials within the bridge structure. Finally, a comparison of real data is performed with synthetic models, allowing the extraction of subtle interpretive information to produce a comprehensive data interpretation.
