This work involves the construction of RC slabs of three bridges on the Okanyoufudai Road between Tanohata Kita IC (tentative name) and Fudai. In this paper, we report the construction system of this construction from the trial construction and the quality confirmation result of the Ashiwatari Overpass constructed as the first bridge.
We obtained the advice before construction from experienced persons, and performed the construction plan and driving based on the results of other companies and the knowledge of the test construction, and constructed our first highly durable RC slab without failure.
