An engineering grand challenge, identified by the National Academy of Engineering (NAE), is to restore and improve urban infrastructure. It is widely known that the aging and failing urban infrastructure is a worldwide challenge. Most recently, the American Society of Civil Engineers (ASCE) has assigned a grade of “D+” to the US infrastructure, across sixteen categories. ASCE estimates that it will cost each American family $31,00 annually in personal disposable income unless the backlog of projects and deferred maintenance are duly addressed nationwide. Engineers of 21st century will have the formidable challenge of restoring and improving infrastructure in view of limited resources and funding. Regarding the transportation systems, it has been recognized that innovative design and advanced materials can provide a more sustainable solution. In this paper, the application of the advanced fiber-reinforced polymer (FRP) composite, a novel construction material—christened the material of 21st century—will be... |
