ABSTRACT:
Arch elements (S) of an overfilled load support structure (L) suitable for use in highway construction are associated with a foundation (F) by a hinge (10). The hinge is formed by edges (12,14) of the arch element bearing on a horizontally disposed load bearing surface (22) and a vertically disposed load bearing surface (24). Essentially unrestrained rotation about the edge bearing on the horizontally disposed surface is permitted, and translation of the element is primarily restrained by the edge bearing against the vertically disposed load bearing surface. The rest of the element is spaced from the foundation.
