Abstract

Aging and deterioration of civil infrastructure such as bridges, railway sleepers, piles and pipelines is a major challenge faced nowadays. Moreover, increased loading together with longer expected design life of such structures make this a complex problem to be resolved. In Australia, there are several timber bridges that have already reached its design service life and needs to be replaced urgently. The limited financial resources to maintain these bridges and the depleting supply of quality hardwood timber have created a need for a cost effective alternative for the replacement of these timber bridges. Engineered fibre composites offer an extremely versatile option to strengthen or rehabilitate existing structures to solve structural problems arising from environmental exposure, inadequate designs, increased traffic loads, and continuous aging. Road and bridge authorities in Australia have become actively involved in these type of projects as many of its existing bridge structures requires replacement and major rehabilitation. This paper will discuss case studies on innovative alternative solutions using engineered composite materials for infrastructure rehabilitation. These projects include sustainable fibre composite bridge girders, pile rehabilitation, composite railway sleepers, strengthening of existing structures and other applications. Overcoming challenges and lessons learned in the implementation of these projects will be also discussed.
