A bridge support system includes a support embankment formed from at least one light-weight material. The support embankment is arranged to support and be positioned under a footing of a bridge structure. A restraining system is operatively connected to the support embankment. The restraining system includes cross-members which are angularly offset from each other and arranged to limit at least one of lateral and vertical movement of the support embankment under high levels of excitation.

A composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross-sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

A structural frame includes a plurality of members formed from fiber reinforced polymer. A pair of the members are arranged to engage one another at a first joint. The joint includes a notch that is provided in an outer surface of the first member of the pair of members and which is arranged to receive an end portion of the second member of the pair of members.

A bridge construction comprises a bridge support or abutment (2) and a bridge deck (1) supported thereon, comprising a composite panel (5) with a top plastic skin (6), a bottom plastic skin (8) and a core (7) between and attached to the plastic skins. The bridge deck also comprises an edge beam (9) on at least one edge of the composite panel and resting on the bridge support. The edge beam (9) overlaps the core (7) of the composite panel (5) in the height direction, while the top plastic skin (6) has a protruding part (28) which protrudes relative to the core (7). The protruding part (28) of the top plastic skin (6) extends over and is attached to the edge beam (9).

A modular bridge is formed from a plurality of bridge modules (4), the bridge (2) having a longitudinal direction along the spanning direction and including: a first longitudinal compression member (11,13, 70) that is, in use, at an upper part of the bridge cross-section; a second longitudinal compression member (9, 72) that is, in use, at a lower part of the bridge cross-section; a structural lateral element (9) for forming a deck of the bridge or for supporting deck elements of the bridge; a shear element (14, 16) for carrying a shear load; and a tension member (6) applying a compressive force to one of the longitudinal compression members (1,13, 70); (9, 72) such that when in use the other of the longitudinal compression members (1,13, 70); (9, 72) forms a main compression element for the bridge (2) and the tension member (6) forms a main tension element for the bridge (2). The bridge modules (4) form segments of the length of the bridge (2) and each bridge module (4) is of a one-piece construction, this single piece including: a segment (10, 12) of the first longitudinal (1) compression member of the bridge; a segment (8) of the second longitudinal compression member of the bridge; a segment (8) of the structural lateral element; and a segment (14, 16) of the shear element; and the bridge modules being arranged to support a portion of the tension member (6).

A composite structural panel for use in bridge structures, and method of manufacturing same, comprises a top panel and a bottom panel separated by and attached to at least one, but preferably a plurality, of structural composite preforms which may be fabricated by a continuous manufacturing process and may be saturated by resin using a continuous wetting process. The composite preforms may take any cross-sectional shape but are preferably trapezoidal. The top and bottom panels may be fabricated from a plurality of layers of woven fabric layers and non-woven fabric layers which are saturated with a resin that is subsequently cured using cure processes known in the art. The composite structural panel of the invention is usable as a flat structural member for use as bridge decking, ramps, trestles, and any application requiring a structural panel.

Bridge including a bridge deck extending in a bridge direction or longitudinal direction of the bridge, and two prefab bridge railings situated on the longitudinal side of the bridge deck, wherein the bridge deck is substantially formed by one or more slabs spanning the bridge width, wherein the bridge railing includes a lower girder provided with a bearing, particularly a bearing edge, for a longitudinal edge strip of the bridge deck.

A modular foundation structure for artificial surface systems may include a plurality foundation sections. Each of the foundation section may comprise a structure base layer, an adhesive layer, and an impact and thermal protective layer. The adhesive layer may cover the structural base layer, and the impact and thermal protective layer may be attached to the structural base layer via the adhesive layer. The foundation sections may be provided as separate foundation sections that may be positionable to be attached to one another to form the modular foundation structure. The foundation sections may be attachable one another with a section adhesive. Embodiments may include a connection edge that may be positioned to surround and abut a perimeter of the modular foundation structure. Embodiments may also include an artificial surface layer that may be positioned to cover an upper surface area of the modular foundation structure.
