Description

Asphalt pavement material recovery device Technical Field The utility model relates to the technical field of asphalt recycling equipment, in particular to an asphalt pavement material recycling device. Background The asphalt pavement material is recovered by converting the waste asphalt mixture into a reusable recycled material through a series of physical and chemical treatment steps. Wherein, a cold milling machine is generally adopted to cut old asphalt pavement into fragments (the particle size is generally 20-50 mm), the cut fragments are loaded and conveyed to a processing site, and then the fragments are further crushed to the target particle size (such as 10-20 mm) by a crushing device. However, the old asphalt mixture contains asphalt binder, and fragments are adhered to each other due to the equivalent principle of asphalt time temperature after the fragments are transported back to a storage yard.
