Skid resistance and noise of roads highly depend on the characteristics of pavement texture. Therefore, the estimation of texture characteristics may give an useful information for the skid resistance and noise of road. As an indicator, MTD (Mean Texture Depth) is generally measured by the Sand Patch Test (SPT). Even though the SPT can be simply conducted with very low cost, it has some disadvantages including time-consuming and traffic interruption. There is a strong need to develop a method to quickly estimate characteristics of road surface textures without traffic interruption and implement it in the expressway pavement management system. In this study, an effective measurement way for the texture depth is developed using the MPD (Mean Profile Depth) which can obtained by the Portable Laser Profiler.
