2011 In 1956 a unique and nearly complete mosaic pavement was discovered within a megaron building at the archaeological site of Gordion, Turkey. Dating to the ninth century BCE, it remains one of the earliest mosaic pavements to be discovered. Its exceptional artistic quality and outstanding condition revealed intricate geometric and abstracted patterns composed of red, white, and dark blue pebbles that distinguished it from other known mosaics of the time. In 1963 Turkish conservators lifted approximately half of the mosaic and backed the lifted sections using reinforced concrete. Despite efforts to preserve the mosaic’s exquisite motifs, the reinforced panels weathered in outdoor storage for years before their installation in the Gordion Museum in the 1980s. Pebble loss from storage and a thin cementitious grout applied over the panels during installation contribute to the now disfiguring display of the pavement; consequently, it remains little known, uninterpreted, and poorly presented. In response, this thesis attempts to (1) construct a written history of the pavement from available documentation, (2) identify and analyze the conditions that have and are affecting its condition and preservation, (3) critique comparable projects that can provide guidance on future work on the mosaic, and (4) propose a phased schedule that can be used to facilitate the conservation of the mosaic pavement in the years to come. |

Soft Capping of Archaeological Masonry Walls |
2006 Assessment of the grout used for the structural stabilization of the Early Phrygian Citadel Gate at Gordion, Turkey Kelly H. Wong Injection grouting for the stabilization of historic masonry structures using traditional hydraulic lime-based mixtures has become increasingly popular in the architectural conservation and civil engineering communities in the past thirty years. Between 2001 and 2005, the Early Phrygian Citadel Gate, an unreinforced masonry structure at the Iron Age archaeological site of Gordion, underwent a structural consolidation program by injection grouting using a hydraulic lime and brick dust mixture, to resist seismic activity in the area. The research presented in this thesis includes an overview of hydraulic lime and crushed brick grouts used in the stabilization of other historic unreinforced masonry structures, the laboratory testing program of three hydraulic lime and brick dust grout formulations conducted in 2006 at the University of Pennsylvania Architectural Conservation Laboratory, and a discussion of test results as it applies to the future stabilization of the Early Phrygian Gate and other historic unreinforced masonry structures in seismically active zones. |
