Abstract

<p> There are 700,000 bridges in Japan. Many of the bridges in Japan were built during the period of rapid economic growth. As a result, the number of bridges that are more than 50 years old is increasing. Many of the bridges in rural areas are of the single span, short-length type, crossing small rivers and agricultural water channel. In addition, many of them are constructed on soft ground. Therefore, it is considered that the impact from passing vehicles will deteriorate the bridges due to the steps caused by the settlement of the back of the abutments. In order to develop a quick and durable step correction method, a test construction was conducted on a bridge with steps near the expansion device. Noise and vibration were measured using a test vehicle before and after construction to verify the effect of the repair.</p>
