N2 - Micro-surfacing mix has been wildly used in pavement maintenance for its water proofing, anti-skidding and wear resistance. However, micro-surfacing has higher noise than common asphalt pavement and its noise can't be measured effectively and accurately. Therefore, this study designs a new indoor noise test method based on wet track abrasion instrument. Firstly, the noise is measured to find out the noise of micro-surfacing is higher than contrastive pavement. Texture Depth (TD) and the exposure rate index of micro-surfacing are proposed as the evaluation indexes to describe the surface properties of micro-surfacing. Secondly, a new indoor noise test method is developed based on wet track abrasion instrument. Thirdly, the low noise gradation is determined based on orthogonal test design method. Finally, the indoor noise of recommended gradation was validated. The result shows that the indoor noise of recommended micro-surfacing gradation can be lowered about 2.5dBA than common micro-surfacing gradation.
