Description

Technical Field

[0001] The utility model relates to the technical field of asphalt mixture production equipment, in particular to asphalt concrete regeneration equipment. Background Art

[0002] Asphalt concrete is commonly known as asphalt concrete. It is a mixture of artificially selected mineral materials with a certain graded composition, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, mixed under strictly controlled conditions. Recycled asphalt concrete is of great significance in terms of technology, economy, and environment when used in highway pavement construction. Recycled asphalt concrete has more application prospects than pure use of new mixed asphalt concrete. After using recycled asphalt concrete, its advantages in reducing energy consumption and enhancing environmental protection are highlighted. Asphalt mixture regeneration technology refers to the technology of reusing asphalt mixture pavement waste that cannot meet the use requirements after treatment through various measures, including digging, crushing, and screening the old asphalt concrete pavement. Then remix it with new aggregates, new asphalt, and regeneration agent (if necessary) to form a mixture with the expected road performance, and re-pave it into various structural layers of the road surface (including surface layer and base layer) according to the process and technical conditions, for the regeneration of asphalt mixture.

[0003] The existing technology has the following problems:

[0004] After searching, for example, announcement number: CN220878687U discloses a device for preparing recycled asphalt concrete waterproof binder. During actual use, the stirring range of the stirring blades on the asphalt concrete is limited, resulting in the asphalt concrete stirring effect close to the stirring blades being relatively ideal, while the asphalt concrete far away from the stirring blades is difficult to stir evenly, affecting the stirring effect and efficiency of the asphalt concrete.

[0005] To this end, we proposed asphalt concrete recycling equipment to solve the above-mentioned drawbacks. Utility Model Content
