On the initiative of the Aluminium Association and in collaboration with the Kamchatka Ministry of Transport and Road Construction in the Russian Far East, preparations are underway to create a model project for the construction of an aluminium flyover of length 12, 5 and 18 metres for the motorway II-V, with size category G8 under load K14.
One foreign and three Russian companies form the working group to develop the model project. The association is currently preparing the project justification and leading a search for funding sources.
The flyover construction up to 8 meters long will close down up to 80% of demand on the bridges along the highway of II – V category. According to the Association’s estimates, just one market for emergency overpasses in Russia consists of 8,500 tonnes. Taking into account the yearly wear of busy bridges, this market will get consistently bigger.
In order to develop the project, the experience and insight of foreign bridge-building companies will be considered. In particular, research will be done on the possibility of using extruded alloy series 6xxx, popular with international bridge-building companies, along with alloy 1915 series 7xxx which is traditionally used in Russia.
Having an approved model project for the construction of aluminium flyovers available would reduce design costs for bridge construction on roads and highways. Design companies can cut costs on staff, and using the model design solutions removes the need to bring in specialists with necessary experience relevant to each individual project.
The finalised technological process outlined in the model project will be a significant factor in lowering the costs of flyover construction. Moreover, the model project will include an algorithm to calculate the economic efficiency of installing aluminium flyover constructions in specific regions, taking into account the logistics and service life of the structure.
Both Russian and foreign specialists are taking part in developing the project, including leading international bridge-building company PML. This will ensure that the structure adheres to modern international requirements, taking into account the construction features and commission of bridges in Russia.
