〇Yuji Suzuki1, Kenji Goto1, Tsutomu Hirata2 (1.kawada construction co.ltd, 2.kyouryougiken.co.ltd)

Keywords:bridge deck, drainage basin, concrete suffering from a freezing and fusing

In conventional bridge drainage basins, the edge of tha basin may be higher than the concrete slab surface. Rain water accumulates in this area may cause deterioration of concrete in cold regions.We have developed a drainage basin that can solve this problem.To confirm this effect, an exposure test is conducting on a conventional drainage basin and a new basin.We report the comparison.
