Abstract

The tunnels that longer than 2km which have been recently constructed have serious noise problems resulting from the friction of vehicle wheels and pavement. In special, concrete pavement inside tunnels with a closed characteristic increases discomfort due to the traffic noise and the dust of pavement pollutes the air in tunnels. Therefore, it is urgent that we find out ways to cope with. This study purported to reduce noise inside tunnels covers the investigation of various pavement surface treatment methods adapted in developed countries, the analysis of the effect in noise reduction and construction methods and cases. The surface treatment method for silent pavement in tunnels reduced noise to 5dB (A)∼10dB (A). Aggregate treatment method is evaluated the most appropriate method in that, related with other surface treatment method, it reduces noise and improves skid resistance. It is necessary for us to introduce equipments and design and rearrange of specification for the development of the silent pavement method in Korea.
