不同路面加铺层抗滑降噪效果室内研究
Indoor study on anti-sliding and noise-reducing of different pavement overlays
摘要
Abstract
In order to study anti-skiding and noise-reducing perfomance of pavement overlays, which include the fiber-rubber micro-surfacing and Novachip ultra-thin wearing layer, in this paper, the influence factors of anti-sliding was researched by the surface structure depth test and friction coefficient test. By calibrating the background noise, the rutting test was used to simulate the effect of tire and pavement to analyze the noise-re-ducing of different anti-sliding layers. The results show that the amount and species of fiber are not significantly affected anti-sliding performance of the micro-surfacing. With the increase of load, the sound level of micro-surfacing was decreased, and that of Novachip ultra-thin layer was increased, but which is far less than that of the micro-surfacing and original pavement. The sound level of fiber-rubber micro-surfacing was decreased about 1.5dB, and that of Novachip ultra-thin layer was reduced by about 3dB after running 8h. The relationship of noise-reducing effect of different overlays is:Novachip ultra-thin wearing layer >polyester fiber-rubber micro-surfacing > basalt fiber-rubber micro-surfacing. The rutting test can be used to evaluate the indoor noise test of different overlays.关键词
