Anotácia

This specification covers the requirements for material, geometric, and wall section properties of aluminum box culverts manufactured from corrugated plate or sheet with attached rib stiffeners, for field assembly. Suitable fasteners and optional materials such as aluminum invert plates and headwalls are also described here. Material applications include surface water gravity flow drainage conduits like culverts and storm drains, small bridge, and grade separation structure conduits like pedestrian or vehicular underpasses, and utility tunnels. This specification does not cover the requirements for foundations, backfill, the relationship between earth cover or live loads and strength requirements, or the hydraulic design of these structures. The required plastic moment capacities should be determined for both the crown and haunch segments of the box culverts.
