Porous asphalts are applied all over the world to minimize the effect of noise caused by everyday traffic. Beside the effect of noise reduction, thanks to their open texture and improved drainage characteristics, porous asphalts decrease the impact of spraying water behind a moving vehicle. Since drainage capability of porous asphalt as a surface permeable layer is much higher compared to a conventional dense-graded asphalt surface course, the values of cross grades of pavement wearing course on the road sections with porous asphalts should be additionally considered. Hence, the primary topic of this paper is how the application of porous asphalt could affect the geometric design of grading plans of pavement surface on urban roads, especially in intersection zones, where different longitudinal and cross grades of intersecting directions have to be mutually aligned. Due to a higher drainage capacity of porous asphalt layers, layout plan of storm water inlets can be changed if pavement c...ross grades are reduced.
