Abstract
A method and apparatus for recycling asphalt shingles in an asphalt plant which heats and dries aggregate and mixes the heated and dried aggregate with liquid asphalt to form an asphalt paving composition. The shingles are comminuted to particles of a size which can be easily flowed and metered, and the shingle particles are introduced into the asphalt plant such that they are heated to melt the asphalt in the shingle particles. The aggregate, heated shingle particles, and liquid asphalt are thoroughly mixed to form an asphalt paving composition.
