Ashlar Arches
In this type, the stones are cut to proper shape of voussoirs, and are fully dressed, set in lime or cement joints along with proper bed joints. Up to depth of 60 cm, the voussoirs are made of full thickness of the arch. Ashlar arches have a good appearance and are used for superior work. Figure 11 displays a few details of segmental, semicircular, and flat arches of ashlar stones.
