Bleeding refers to the accumulation of asphalt binder (cement) on the pavement surface - normally in the wheelpath areas. Bleeding can be caused by excess asphalt cement and/or insufficient voids in the asphalt mix, with the excess asphalt being flushed to the pavement surface by wheel loads during hot weather. Pavement areas affected by bleeding reduce the friction available for aircraft braking and can become very slippery - especially when wet.
