Description

Technical Field

[0001] The utility model relates to the technical field of asphalt thermal regeneration, in particular to an old material recovery device for thermal regeneration of asphalt pavement. Background Art

[0002] Asphalt is a black, viscous substance that is mainly used for paving roads and making products such as asphalt cloth. It is mainly composed of carbon, hydrogen and other elements, and is usually used at temperatures below its melting point. Asphalt has good water resistance and corrosion resistance, making it a widely used building material. Asphalt will have recyclable raw materials such as old asphalt after long-term use. Thermal regeneration technology is a method of repairing and protecting asphalt pavements that have aged and damaged. Usually, maintenance and renewal are required after the service life of the road reaches a certain extent. The thermal regeneration process involves the process of heating the old asphalt mixture and re-paving it, so that the road surface can be restored to its original height and usage level, so it is necessary to use the old asphalt thermal regeneration recovery device.

[0003] During use, the existing waste material recycling hot regeneration equipment usually performs hot regeneration by heating and stirring the asphalt material. However, the asphalt blocks cannot be crushed before stirring the asphalt. The heating and stirring speed of large pieces of asphalt is slow, which affects the asphalt hot regeneration efficiency. In addition, a large amount of gravel and stones will remain in the recycled asphalt material. The existing technology cannot screen out the gravel and stones in the asphalt, which will result in the presence of gravel and stones in the asphalt after hot regeneration, affecting the smoothness of subsequent asphalt pavement paving.

[0004] Therefore, it is necessary to provide a new waste material recovery device for hot regeneration of asphalt pavement to solve the above technical problems. Utility Model Content
