貯蔵してから使用している。2. Description of the Related Art When the ground is dug up for road construction, etc., a large amount of asphalt pavement waste material (hereinafter referred to as "waste material") is generated. For this reason, recently, asphalt pavement waste materials are often mixed into new asphalt mixtures in appropriate amounts for recycling. The waste materials brought from the construction site to the asphalt mixture manufacturing factory are piled up in large chunks on the factory grounds. Then, as necessary, a predetermined amount of the waste is taken out using a shovel loader and carried to a crushing device, which crushes it and temporarily stores it in a waste material hopper before use.

に、廃材の貯蔵、供給の自動化の弊害となる。Furthermore, a shovel loader is often used to take out waste materials piled up in the open, and if the shovel loader is constantly operated in parallel with the operation of a waste material recycling plant, it will cause problems in terms of noise and securing personnel. This poses a problem and also becomes an adverse effect on the automation of storage and supply of waste materials.

The waste material is roughly crushed to about 0.00 mm, and the crushed waste material is stored in a water tank. The buoyancy of the water reduces the compaction of the waste wood due to its own weight, and the presence of water weakens the stickiness of the asphalt, reducing the chance of the waste wood sticking together, allowing the waste wood to be stored in crushed particles.

Then, the waste materials brought in from the construction site by the dump truck 2 are put into the primary crushing device 1.
Then, the waste material of about 1000 mm is crushed into pieces of about 150 to 200 mm. This primarily crushed waste material is put into a water tank 4 by a conveyor 3, and is submerged in water stored in the water tank 4 for storage. When waste wood is stored in water in this way, the buoyancy of the water can reduce the compaction caused by the waste wood's own weight, and the presence of water can weaken the stickiness of the asphalt and reduce the sticking of waste wood particles to each other. Even waste materials containing sticky asphalt can be stored well.

として再生されるのである。In response to a request for production of an asphalt mixture, waste material is picked up from the water tank 4 by a grab bucket 10 and taken out to a receiving material hopper 11 while being drained. The waste material primarily stored in the receiving material hopper 11 is cut out into appropriate amounts by a waste material transfer conveyor 12 and sent to a secondary crushing device 13. At this time, a certain amount of water is attached to the waste material, but since the particle size of about 150 mm is crushed by the secondary crushing device 13 to about 20 mm or less, the surface area increases and it becomes attached to each particle. The amount of moisture that is released does not cause any practical problems. The waste materials crushed by the secondary crushing device 13 are stored according to particle size and recycled as asphalt mixture.
