Abstract
The main objective of this paper is to evaluate the field applications and the noise reductions of micro surfacing pavement, which is often used to reduce environmental problems. A traffic noise mechanism was analyzed and a modified mix design method was proposed for nighttime constructions. Results on noise measurements using the statistical pass-by method showed noise reductions of 2.0 to 7.1 dB were observed. In addition, results on noise measurements using the close proximity method demonstrated that noise reductions of 5.6 to 6.7 dB were recorded under vehicle speed of 80km/h. The noise measurements revealed that the close proximity method was more stable than the statistical pass-by method. As a result, the effect of micro surfacing pavement on noise reductions was proved through the research. It is considered that the micro surfacing pavement method could be used as a preventive maintenance method and a comfortable noise reducing pavement technique.
