ABSTRACT:
An arch-beam structure for use in combination with a culvert or the like includes a panel, which is cast or placed on the usual metal culvert conduit, the panel covering the top of the conduit, and having arms extending horizontally outwardly beyond the sides of the conduit for the purpose of transferring loads occurring on the panel-conduit system to the soil at the sides thereof, confining and thus increasing resistance to failure in the area of the soil or backfill materials adjacent to the structure.
