Abstract. The objective of this study is to conduct a mineralogical and chemical characterization of the mortars Roman archaeological site of Volubilis to rebuild spare mortars for restoration. Samples of mortar, broken tile palate garden, and pavement mosaic Falavius Germanus. The analysis by X-ray diffraction reveals that the coarse mortar Flavius Germanus is made of quartz and calcite, with feldspar and probably, mica and dolomite in small amounts. The binder end is formed calcite and quartz. However, the broken tile mortar is formed by coarse particles, clay base mixed with a binder phase dominated by calcite. These results allowed us to reformulate spare mortars for the restoration of damaged Roman mosaics, the mortars are made up by 63.6% of lime and 36.4% of sand(with (4.19% of large grain, 71, 04% of coarse sand, 24.22%, of fine sand and 0.55% fines parts). The performance of these mortars was tested by mechanical testing.
