The inspection done after one year (full year season with high temperature gradients
summer versus winter time) proved that there are no cracks and no evidence of significant
movement of abutments can be noticed for realized bridges. This was the case for differ-
ent configurations including significant skew. The solution applied for this critical detail
(“Fig. 20”) consisted of a special layer of composite applied in the asphalt and two chases 20
mm width spaced about 400 mm filled with bituminous material. Extensive documentation of
the construction of VFT and VFT-WIB bridges at the S7 road and many pictures can be found
