The main line of National Route 1 is the second longest land-based route on the island of Honshū, Japan. Along the route, near the city of Kakegawa, runs a 600 meter long twin road tunnel.
Bekaert provided Dramix® steel fibers for the final lining of this tunnel as well as an automatic dosing machine to control the addition of the steel fibers to the concrete mix as and to measure the final steel fiber content of the wet concrete mix.
