Disclosed invention comprises innovations related to the fabrication process and the associated design of Prefabricated Link Slabs made using Ultra High-Performance Concrete (UHPC) for bridges hereinafter referred as PLS-UHPC. This disclosure is regarding methods of designing, manufacturing, and installing PLS-UHPC as connections between bridge spans. The invention includes the concept of installing PLS-UHPC which will provide numerous benefits such as faster construction in the field, and better maintenance of established systems.

This invention is the concept and method of designing, fabricating in a factory environment and installing Deck Joint Systems (DJS) consisting of Ultra High Performance Concrete (UHPC) joint headers sandwiching the joint sealer and pre compressing the sealer using a plurality methods for applying compression. The deterioration of bridges due to the exposure to chlorides, most commonly from leaking joints, has been established as the biggest challenge for bridge owners in the US and abroad. In general, the lack of performance of deck joint systems constructed using state of the art practices is causing accelerated bridge deterioration, especially in areas where deicing chemicals are used.

A segmental joint of cast-in-place UHPC bridge beam. The joint comprises a female joints at an end of a first segment and male joints at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure improves the structural strength of the bridge and facilitates on-site construction, which not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.

The present disclosure relates to a segmental joint of cast-in-place UHPC bridge beam, and belongs to the field of bridge structure. The joint comprises a plurality of female joints disposed at an end of a first segment and a plurality of male joints disposed at an end of a second segment, wherein each female joints and the male joints are correspondingly connected to form a tongue-and-groove connection, and each of the male joints is of a structure with big outer part and small inner part. The beam segment joint of the present disclosure not only applies to the joint connection between the segmental cast-in-place UHPC beam segments and the construction of the segmental cast-in-place UHPC beam segment, but also to joint connection of UHPC bridge deck of UHPC-steel composite beam and of full UHPC bridge deck of UHPC composite box girder with corrugated steel webs and to UHPC bridge deck construction.

A drivable building structure is provided including a first partial construction and a second partial construction movable relative to the first. The first partial construction has a first substructure and a first roadway structure which forms a first drivable surface, and the second partial construction has a second substructure and a second roadway structure which forms a second drivable surface. An expansion joint is between the first substructure and the second. A bridging structure extends between the first roadway structure and the second. The bridging structure spans the expansion joint and has a support plate and an expansion body. The expansion body is supported by the support plate, is cast on site from casting compound, and forms a drivable surface. The expansion body casting compound is polymer-based. The expansion body has a multi-layer structure produced in successive casting operations, and at least two of the layers have different compositions.

A method of waterproofing a bridge expansion joint, gap between a pair of bridge decks or a bridge deck and a ground deck, implemented through a layer of primer, an elastic membrane, a waterproofing membrane, a reinforced membrane, and a repaving process. As the first step, the layer of primer is applied to adjacent ends of the pair of bridge decks or the bridge deck and the ground deck. The elastic membrane is then shaped to an inverted dome and positioned within the gap as terminal ends of the elastic membrane are thermally bonded to the layer of primer. The waterproofing membrane is then thermally bonded to the layer of primer and the elastic membrane. Then, the reinforced membrane is thermally bonded onto the waterproofing membrane along the bridge expansion joint. The repaving process is then executed to install an asphaltic plug, completing the waterproofing of the bridge expansion joint.

A roadway joint device for providing a drivable joint section between a road and an adjoining structure, particularly a bridge structure, includes at least one joint element placed on a sliding surface adjacent to the bridge structure. A longitudinal axis of the joint element is arranged substantially parallel to a plane of the roadway and a bridge end section of the bridge structure. Joint gaps with a specified gap width are arranged between the joint element and the adjoining bridge end section and/or an adjoining retaining device arranged at a distance to the bridge end section. The joint element is attached to at least one rod, the rod being arranged substantially in the direction of the longitudinal axis of the bridge structure, anchored at one rod end in the bridge structure and another rod end thereof in the retaining device.

A transition slab connected at opposing ends to a deck compression slab and to an anchoring. The transition slab absorbs the expansions of the deck by means of compressing sheets of polymer, elastomer or the like, that are arranged in parallel spacing and integrated in the transition slab to be oriented perpendicular to the longitudinal direction of the road. The transition slab absorbs the contraction movements of the deck limited expansion due to the summation of crack openings in induced cracks. Crack planes are created by forms made of wood, polymer or the like arranged in parallel, spaced relation within the body of the transition slab.
