Abstract. This article presents a comprehensive analysis of the performance of a composite superstructure during the implementation of a construction and installation technology for replacing a reinforced concrete driveway slab with a new orthotropic metal superstructure along half the roadway while simultaneously accommodating transit traffic.

The design parameters of a double-girder composite superstructure, using the 43282KM standard design, the most common in the Far East, are examined in detail. The main cases of specific superstructure loading by process equipment, mechanisms, and transit traffic are identified.

The authors present a comprehensive analysis of the performance of a composite superstructure during the driveway slab replacement during the dismantling phase. It is determined that the load-bearing capacity of the main beams is ensured. However, certain structures, particularly transverse ties, do not ensure stability during the implementation of the work; recommendations for their reinforcement are provided. The article clearly confirms that the key condition for the successful reconstruction of composite bridges along half the roadway during the production process is the construction of a temporary support under the superstructure.

The article presents an example of the reconstruction of composite superstructures according to standard design 43282KM for the bridge across the Bystraya River in Kamchatka Krai using a temporary support. This serves as a full-scale demonstration of the implementation of individual research results. The positive values obtained for the design coefficient as a result of static tests confirm the effectiveness of the proposed solutions for converting the superstructure to an all-metal one.
