Assessing the impact of the slopes on runway drainage capacity based on wheel/path surface adhesion conditions

Aircraft braking distance is dependent on the friction between the main gear tires and runway pavement surface.Pavement texture, which is divided into macrotexture and micro-texture, has a noticeable effect upon friction, especially when the surface is wet. A risk analysis framework is developed to...
