| Abstract: |
In Switzerland, a considerable number of transportation infrastructure rehabilitation projects are expected till 2020. In this new context of mobility, rehabilitation projects have become increasingly complex under various constraints, such as the traffic maintenance under reconstruction and the rapid facility delivery with the minimum cost. This paper brings insights from our practice on how new technologies such as the Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) and the fiber composite sandwich decks could be leveraged for the best satisfaction of these macro constraints. The assessment is based on two criteria of the facility delivery time and the traffic control under reconstruction. The application of UHPFRC is discussed both as a waterproofing layer integrated to the pavement layout and also as a promising reinforcement technology for concrete deck rehabilitation. A project is also reviewed highlighting a fiber composite sandwich deck as a replacement solution enhancing a rapid facility delivery. |
