Özet
Perpira is a registered ancient bridge, probably constructed during the Late Roman/Early Byzantine, to
span the banks of the Batman Stream. The foundations and the piers are the surviving remains of this
bridge. It is known that the bridge has not been repaired since it was discovered. Therefore, the remaining
parts of the structure, especially the cut stone blocks, are original and contain precious information about
the construction techniques and material selection of the period in which it was constructed. During the
site investigations, it has been found that the stones used in the downstream and upstream sections seem
to be different. In order to examine this unique application, samples were collected from the piers'
downstream and upstream sections. The samples were then used to evaluate their petrographic,
geochemical and engineering properties. At the macro scale, the questioned samples' petrophysical
characteristics seem similar. The variations in the physicomechanical, petrographic, and mineralogical
characteristics of stones used in these sections, however, indicate that they have noticeably different
properties. The laboratory results demonstrate that the stone used in the downstream section is dolomite
and has a strength of 25.21 MPa and a porosity of 25.38 percent, while the one used in the upstream section
is limestone and has a strength of 59.93 MPa and a porosity of 5.80 percent. According to the experiment
results, it can be stated that Romans constructed this structure using highly competent engineering
knowledge and material optimization. The findings also highlight how even a single piece of artefacts may
provide new insights for understanding ancient material application practices.
