RESEARCH ON STEEL FIBER REINFORCED CONCRETE PAVEMENT FOR ORTHOTROPIC STEEL DECK AS A COUNTERMEASURE FOR FATIGUE

This paper describes ongoing studies about application of Steel Fiber Reinforced Concrete (SFRC) pavement for existing orthotropic steel deck as a countermeasure for fatigue problems. Public Works Research Institute (PWRI) and several companies are now conducting joint researches on repair/reinforcement methods including SFRC pavement. In order to evaluate durability of the pavement, strength tests and fatigue tests under negative bending have been conducted using half meter size specimens taking into account of effects of reinforcement in SFRC and influence of water. Wheel running test using real size specimen will get started in the beginning of 2008
