Roadway paving apparatus
 A roadway paving apparatus applies successive layers of paving material to a roadway surface so as to form a desired thickness of pavement thereon. Preferably, the apparatus comprises a hopper for hauling aggregate material (e.g., gravel, sand, and/or crushed stone) and for dispensing a curtain of falling aggregate material therefrom. An initial group of spray nozzles aimed generally at the surface of the roadway applies a base layer of adhesive material (e.g., liquid asphalt) to the surface of the roadway. One or more groups of subsequent spray nozzles aimed generally at the curtain of falling aggregate material coats the curtain of falling aggregate material with adhesive material such that an intermediate layer of adhesive coated aggregate material is deposited on top of the underlying base layer of adhesive material. A final group of spray nozzles aimed at the surface of the roadway applies an overspray layer of adhesive material on top of the intermediate layer of adhesive coated aggregate material. A corresponding method of paving a roadway surface by applying successive layers of paving material the surface is also provided.
