Abstract:
To provide an asphalt mixture manufacturing method that can suppress noise, vibration, dust, etc., and can be also expected to improve efficiency of recycling waste materials.SOLUTION: A waste material block dug up in a road construction is put into a primary crusher 1 to be primarily crushed, and then the waste material block discharged from this primary crusher 1 is put into a secondary crusher 3 to be secondly crushed. Then, an entire amount of the waste material mass discharged from the secondary crusher 3 is supplied, with original particle sizes thereof maintained, to a waste material dryer 6 without being circulated and supplied to the secondary crusher 3. Then, in the waste material dryer 6, the supplied waste material mass is cut by a waste material mass shredding body provided projectingly on an inner drum wall while being heated by radiant heat of a burner flame formed in a former half part of a drum 7, and then raised and dropped with raising blades in a latter half of the drum 7 so as to be heated and crushed by applying impact force while being exposed to hot air from the burner 13.SELECTED DRAWING: Figure 1
