PROBLEM TO BE SOLVED: To reduce labor cost and to solve a quality control problem by delivering asphalt by screws in steel pipes, and paving in specific width, combining compaction by an iron. SOLUTION: In paving work, asphalt is delivered by the rotation of screws provided in steel pipes in an automatic asphalt paving machine with a paving width of 600 mm-1200 mm to pave combining compaction using an iron. Because of simple structure of providing the screws in the steel pipes to deliver asphalt, the machine can be operated even by two or three common workers at the minimum. The iron is formed in bow shape to facilitate the spread of asphalt. Manual construction work is thereby replaced with mechanical construction work to reduce labor cost and the like by a large margin and to solve a quality control problem such as a rough finish of a pavement caused by the temperature drop or the like of asphalt during manual construction work.
