摘要

The paper discusses the current and potential uses of fibre reinforced composites by the UK Highways Agency to strengthen concrete highway structures, and for more fundamental structural applications. It will provide background to research that has been carried out by the Agency, but also identify needs for future work. The advantages of fibre reinforced composites are well known, and have been established in the aerospace and marine industries. However there are still reservations about the use of composites such as glass, aramid, and carbon fibre in construction. They are light and easily handled materials and not subject to corrosion, and are therefore a low maintenance and durable option for bridge decking and strengthening of structures. There are however some potential disadvantages using composites, and areas of uncertainty such as longer term durability. The Highways Agency has undertaken a number of projects to use composites to strengthen existing structures. There have been two main applications - column and deck strengthening, primarily for impact loading and bending. The paper highlights several case studies and the development of design guidance and specifications, and the need for quality control systems and procedures for management of composites.
