Spray plume
As a spray plume is surface water which is stirred up when traveling over a wet road with a vehicle referred. The reason for this is a suction that prevails under the vehicle from a certain speed. The whirled up water can severely obstruct the view and increase the risk of accidents.
In order to avoid the formation of spray plumes as far as possible, the surface water must be drained off as quickly as possible. This task is usually carried out by the cross slope of the roadway. However, heavy precipitation and unevenness in the roadway ( e.g. ruts ) can impair the rapid runoff of surface water. So-called open-pored asphalt surfaces (also known as drain asphalt ) are particularly effective . Due to the large cavities in the asphalt, the surface water penetrates the surface course and is drained there, which means that spray plume formation can be almost completely prevented.
