Technical Field

[0001] The utility model relates to the technical field of road engineering machinery and equipment, in particular to asphalt mixture cold regeneration mixing equipment. Background Art

[0002] Natural solid asphalt granules are a natural asphalt additive material that is in solid granular form at room temperature. Natural solid asphalt granules are asphalt minerals formed by the combined effects of temperature, pressure, oxidation, etc. after hundreds of millions of years of sedimentation and change of petroleum in the cracks of rocks. The asphalt content inside natural solid asphalt granules is about 20%, which can replace the asphalt content in asphalt mixtures. At the same time, natural solid asphalt granules have extremely high stability and can significantly improve the road performance when added to asphalt mixtures. In the cold recycled aggregate and asphalt of asphalt mixtures, no heating is required. The mixing tank is continuously added with the materials put in sequence to produce qualified asphalt mixtures.
