The present study has been carried out to investigate the relationship between the surface profile of road and tire/road noise for concrete pavement, particularly concrete pavement with exposed aggregate, for reducing noise. A method for reforming road surface is adopted to change profile by maximum size of exposed coarse aggregate. This study was performed to evaluate the road profile by changing aggregate size and to examine the influence on the tire road noise where consists of the air pumping noise and the tire-vibrating noise. The measurement of the tire-vibrating noise was executed with a measurement device of the drum type to the examination road specimen bound aggregate with epoxy resin. Next, the measurement of the air pumping noise used a measurement device of the tire fall type, to examination road specimen of concrete and asphalt materials.This study clarified the following.1. The road profile changing by used aggregate size can be evaluated by using the frequency distribut … More ion of the road depth.2. The tire/road noise by the tire-vibration increases when aggregate size increases, and furthermore the amount of the tire/road noise increases when the speed increases, with the drum type noise measurement device. The convex part interval of the road where the tire-vibration noise is led to an increase for the speed exists.3. When it makes aggregate size large, the tire/road noise decreases by reducing the air pumping noise because the gap on the road surface causes, being generated by 2kHz or more, with the fall type noise measurement device. Moreover, best aggregate size exists being reduce the air pumping noise.From the above-mentioned, as for aggregate size, it is that aggregate size being small decreases the tire vibrating noise and aggregate size being large decrease the air pumping noise. Therefore, it is considered that optimum aggregate size is obtained by examining the ratio of the element on tire-vibrating noise and the element on air pumping noise as an element of the tire/road noise when really running.

为了降低混凝土路面的噪声，本文研究了混凝土路面，特别是暴露集料的混凝土路面的路面形状与轮胎/路面噪声之间的关系。提出了一种利用暴露粗集料最大粒径改变路面纵断面的方法。本研究旨在探讨改变集料粒径对路面轮廓的影响，并探讨集料粒径对轮胎路面噪声的影响，其中轮胎路面噪声包括轮胎充气噪声和轮胎振动噪声。用转鼓式测量装置对环氧树脂结合集料的试验路试件进行了轮胎振动噪声的测量。其次，在抽气噪声的量测上，使用轮胎坠落式量测装置，以混凝土及沥青材料的道路试件进行量测。利用频率分布可以评价骨料粒径对路面纵断面的影响 ...更多信息 道路深度的离子。对于鼓型噪声测量装置，当聚集体尺寸增大时，由轮胎振动引起的轮胎/道路噪声增大，并且当速度增大时，轮胎/道路噪声的量增大。存在导致轮胎振动噪声随车速增大的路面凸部区间.当其使集料尺寸大时，通过降低空气泵送噪声来降低轮胎/道路噪声，这是因为路面上的差距导致的，使用下落式噪声测量装置产生2kHz或更高。此外，存在降低充气噪声的最佳骨料粒径，从上述可知，对于骨料粒径而言，小骨料粒径降低轮胎振动噪声，大骨料粒径降低充气噪声。因此，可以认为，通过检查作为实际行驶时的轮胎/道路噪声的要素的轮胎振动噪声要素和空气泵送噪声要素的比率，可以获得最佳聚集体尺寸。少
