Composite rehabilitation systems reinforcements

Composite rehabilitation systems (CRS), i.e., structural hybrid systems involving advanced polymer composite (APC) materials (generally referred to as fibre-reinforced polymer, FRP), structural adhesives (SA) and conventional construction materials (CCM) (e.g., timber, concrete, masomy, steel, iron), constitute one such technology. 

Abstract This chapter continues the discussions of the development of advanced polymer composite material applications associated with bridge engineering. It focuses on the rehabilitation of metallic bridge structures, all-FRP composite bridges and bridges built with hybrid systems. Chapter 16 covered the materials used in FRP composites, in-service properties and applications of FRP composites in bridge enclosures, the rehabilitation of reinforced and prestressed concrete bridge beams and columns.

A composite system was used to rehabilitate a concrete bridge deck. The reinforcement works were carried out in the scope of a pioneer research project in Portugal in this area, promoted by the Portuguese Innovation Agency, named Strengthening of bridges with advanced composite -... 

Use of composites to rehabilitate existing infrastructure is not dealt with in this chapter due to space limitations. However, readers must note that great strides are being made in applying polymer composite wraps and laminates to reinforce the infrastructure systems in a cost-effective manner so that hundreds of millions of dollars can be saved through the rehabilitation techniques with a simultaneous reduction of user inconveniences.
