Abstract
It is known that the noise reduction effect of low noise pavement is affected by both of its surface texture and the state of air voids. At the present, surface texture is evaluated by a few profile data on the single measuring line on the pavement surface. Therefore, it follows that the evaluation of the texture of the whole pavement surface is difficult by the use of the present procedure due to the variation of the surface conditions.
In this paper, a fundamental study on a sampling of precision data and an analysISOf them were carried out for evaluating the texture of the whole pavement surface, based on the way of plane measurement of the pavement profile. As a result, it is shown the variation tendency of the texture for the whole pavement surface and a minimum number of the profile data for analyzing the whole surface texture. Furthermore, a probability of the evaluation of the whole surface texture with accuracy is also shown in consideration of the selection of the present analysis procedures.
