Description

It is urgent task for road administrators to establish a recycling system of the wastes in construction sites and rest areas on expressways. In this paper, it is reported the development of recycled concrete aggregate made from a part of the wastes and the test results of the performance of the concrete noise barrier that includes the recycled aggregate.<br>As the results, the recycled concrete noise barrier has about the same level performance in terms of the effect of intercepting noise and the load-carrying capacity compared with that of the conventional concrete noise barrier. In addition, the cost of the recycled concrete noise barrier is 15% less than that of the conventional one.
