Multifunctions type drainage pavement has a drainage function equivalent to drainage pavement near the surface in the same surface layer, and the lower part has a contexture of the hybrid pavement having waterproofing performance equivalent to SMA. Furthermore, this pavement characterized by this pavement forming a longitudinal groove in the pavement surface at intervals of 4 cm, and since this longitudinal groove has an effect which improves skid resistance, it can control the slide in the curve part of pavement. It is proved by the curve of the national road No. 25 named “Meihan Kokudo” from these things that this pavement can reduce a slip accident. This report evaluates quantitatively the stability at the time of sharply braking of vehicles especially about the effect which controls the slip of this pavement.
