ARCHED BUILDING
The broken, cracked or deformed ceiling slabs (Fig. 1) of the structure were drilled (Fig. 2) at two points each and fitted with stainless steel-chrome dowels with a length of 80 cm and diameter of 30 mm; these dowels and broken surfaces were fitted using epoxy resin (Fig. 3).
The southern arches of the fifth, seventh and tenth rows had fallen; some blocks of the first row of arches slid causing the balance to deteriorate in the south. Thus, all the concerned blocks were photographed, documented and carried to the stone field using a crane (Fig. 4). Some parts of the fifth and tenth rows were missing or had deteriorated so much that new stone blocks had to be prepared to replace them.
In order to facilitate the restoration of arches the earth filling under them were left unexcavated at suitable heights. Then wooden moulds following the curvature of the actual arches were put up and restored blocks in the stone field were brought back and placed (Fig.5). Lead pieces were inserted in the gaps between the blocks and filled with mortar (Fig. 6).
Following the placement of the voussoirs, the masonry of creek stones and travertine between the two rows of arches and where the southern arches join the southern wall were rebuilt using the original materials collapsed and tasting them in place first; the gaps between the voussoirs and the walls were filled with travertine mortar, thus completing the restoration work (Fig. 7). The broken blocks of the fourth row were cleaned of their dead layers and were adhered using epoxy resin after probation, and compressed with bench clamps (Fig. 8). When the restoration of the rows of arches was completed then the ceiling slabs were placed on their original positions; the gaps between these slabs and the arches were filled with travertine mortar (Fig. 9).
