The usage of brushwood, branches or rods in road construction is documented across the Medieval Europe, from Denmark to the Balkans. The bundles of tree-branches, or ”fascines”, are used to fill and repair holes in the road surface, as a temporary measure. The fascines are construction materials very versatile, used since Antiquity as means to fill trenches during sieges, to allow the passage of assault troops or war machines. In road construction, the fascines were used extensively as shoring material, i.e. to strengthen and support the embankments, or as casing lining to provide a bed that was vertically and laterally stable when the road was built over unstable or swampy terrain. The fascines are ideal emergency repair material, as these are light, stable and in the same time bulky, with a very good strength-to-elasticity ratio. These features are present, though, only for a short time, as the both the branches and the bundles are quite perishable, even when weather resistant and tough wood is used (birch, oak, hazel or alder). However, there are instances when the usage of such construction material goes beyond the temporary patching of holes, the thick layer of lined-up branches making a continuous road surface both practical and resilient, although not very long-time resistant to the elements.
