A building structure, particularly a road bridge structure, has an upper part (6-10) adapted to carry traffic, and a lower part (2) supporting the upper part. The two parts are separated by a non-adhesive, low friction membrane (1) having hood portions (4) fitting around anchorage blocks (3) projecting upwards from the surface of the lower part. The upper part comprises a course of pavement blocks (7) in which blocks are omitted to form a void around each anchorage block (3), the voids being filled with concrete (9). At least one asphalt layer (10) is laid on top of the pavement blocks (7). Liquids penetrating through the upper part are prevented by the membrane (1), including the hood portions (4) from penetrating into the lower part (2) and are drained off above the membrane (1). Horizontal forces resulting from traffic are transmitted via the asphalt layer (10), the pavement blocks (7), the concrete filling (9), the hood portions (4) and the anchorage blocks (3) to the lower part (2). |
