<P>PROBLEM TO BE SOLVED: To provide an asphalt-coated and corrugated steel plate for a water way, which can restrain a crack from being formed in an asphalt mixture at a low temperature. <P>SOLUTION: In this asphalt-coated and corrugated steel plate for the water way 1, an inner surface of the curved and corrugated steel plate 2 is coated with the asphalt mixture 3 in such a manner as to form a smoothed inner surface. In the asphalt mixture 3 for use, 2-6 kg discontinuous fibers are mixed into each cubic meter of an asphalt mixture 3 which does not substantially contain aggregate, which contains 75±2 wt.% blown asphalt and the rest of which is occupied by a filler. <P>COPYRIGHT: (C)2010,JPO&INPIT |
