Testing has begun of advanced pultruded composite profiles intended for the construction of a prototype highway bridge in Oxfordshire next year. Developed by a European consortium led by composite structures specialist Mouchel, the two-cell fibre reinforced polymer profiles will undergo 150 large scale tests at Spanish research institute IETCC, which is also a consortium member. A 225mm deep by 520mm wide version of the profile is now in production in Denmark. More than 30 of the two cell profiles will be bonded together side by side to form the deck of the 10m span bridge, supported by four composite box beams.
Complete with concrete upstands, diaphragms and parapets, the finished structure will weigh just 27t, less than the 95t of a conventional replacement.
