Abstract (en)
[origin: WO2023110603A1] The invention relates to a drivable construction (1), comprising a first partial construction (2.1) and second partial construction (2.2) movable relative to the first partial construction, wherein the first partial construction (2.1) comprises a first substructure (3.1) and a first roadway structure (4.1), which forms a first drivable surface (5), and the second partial construction (2.2) comprises a second substructure (3.2) and a second roadway structure (4.2), which forms a second drivable surface (5). According to the invention, there is an expansion joint (7) between the first substructure (3.1) and the second substructure (3.2). A bridging structure (9) extends between the first roadway structure (4.1) and the second roadway structure (4.2). The bridging structure spans the expansion joint (7) and has a support plate (17) and an expansion body (10). The expansion body is supported by the support plate, is cast on site from casting compound, and forms a drivable surface (8). The expansion body casting compound is polymer-based. And the expansion body (10) has a multi-layer structure produced in a plurality of successive casting operations; at least two of the layers (31, 32, 33) of the expansion body (10) have different compositions.
