The technologies used in Japan for designing and constructing bridges and slabs with UFC(Ultra-high strength Fiber-reinforced Concrete) have advanced over the past ten years. This paper describes two recent UFC applications: the Kayogawa Bridge, and the Runway D extension at Tokyo International Airport.

The Kayogawa Bridge was the first railway bridge in the world to be constructed of UFC. The use of UFC resulted in a thinner slab and a lower project cost. This paper describes the design and construction of this bridge, as well as the results of displacement and noise measurements.

The Runway D extension project is still the world’s largest application of UFC. Approximately 6,900 UFC slabs with a total volume of 22,000 m3 were placed in a 192,000 m2 area of Runway D. Using UFC rather than conventional concrete reduced the weight of the slabs by 56%. This paper describes the design and mass production of these slabs.
