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.

已经进行了本研究，以调查道路和轮胎/道路噪声的表面轮廓之间的关系，以使混凝土路面，尤其是裸露的聚集体的混凝土路面，以降低噪声。采用了一种改革道路表面的方法来改变最大裸露的粗骨料大小。进行这项研究是为了通过更改骨料大小的变化并检查对轮胎道路噪声的影响来评估道路剖面，在该噪声中由空气抽水噪声和轮胎振动的噪声组成。用鼓类型的测量设备与考试路标的测量装置一起执行轮胎振动噪声的测量。接下来，空气抽水噪声的测量使用了轮胎秋季类型的测量装置，用于检查混凝土和沥青材料的路标。这项研究阐明了以下内容。1。可以使用频率分配的频率进行评估，可以通过使用的频率进行更改。道路深度的更多离子2。当聚集体尺寸增加时，轮胎振动的轮胎/道路噪声会增加，并且随着滚筒型噪声测量设备的增加，轮胎/道路噪声的量会增加。在速度上增加轮胎振动噪声的道路的凸零件间隔。3。当它使总尺寸大时，轮胎/道路噪声通过降低空气泵噪声而降低，因为路面的缝隙是由2kHz或更多的，并使用秋季类型的噪声测量设备产生的。此外，最佳的总尺寸会降低空气泵的噪声。从上述尺寸（对于总尺寸）中，骨料尺寸很小会降低轮胎振动的噪声，而聚集体尺寸很大，大小降低了空气泵的噪声。因此，可以认为，通过检查元件在轮胎振动的噪声和空气泵噪声上的元素的比率是获得最佳的总尺寸，这是真正运行时轮胎/道路噪声的元素。较少的
