In-situ in-situ cold regeneration method for asphalt pavement
The invention discloses an asphalt pavement in-situ cold regeneration method, which belongs to the technical field of asphalt pavement repair, and comprises the following steps: shoveling, crushing and stripping an old asphalt pavement, and finally mixing old stone with a binder, a modifier and water in cold regeneration mixing equipment for cold regeneration to obtain an asphalt mixture. According to the invention, the old asphalt pavement is entirely shoveled by using the old asphalt pavement shoveling equipment, and then the shoveled old asphalt pavement is flexibly crushed by using the old asphalt pavement material crushing equipment to form small crushed aggregates; then stripping the old asphalt pavement crushed aggregates by using old asphalt pavement material stripping equipment to obtain old stones; and finally, mixing the old stone with a binder, a modifier and water in cold recycling mixing equipment, and performing cold recycling to obtain the asphalt mixture meeting the requirements. By adopting the method, the in-situ cold regeneration of the old asphalt pavement can be realized, the asphalt pavement repairing process is simplified, and the construction efficiency and the construction quality are improved.
本发明公开了一种沥青路面原位就地冷再生方法，属于沥青路面修护技术领域，包括旧沥青路面的铲削、破碎及剥离，最后将旧石料与粘结剂、改性剂和水在冷再生拌合设备中混合冷再生得到沥青混合料。本发明利用旧沥青路面铲削设备将旧沥青路面整体铲除，再利用旧沥青路面材料破碎设备将铲削下来的旧沥青路面进行柔性破碎，形成小块碎料；然后利用旧沥青路面材料剥离设备剥离旧沥青路面碎料得到旧石料；最后将旧石料与粘结剂、改性剂和水在冷再生拌合设备中混合冷再生得到符合要求的沥青混合料。采用本发明能够实现旧沥青路面的原位就地冷再生，简化了沥青路面修补工艺，提高了施工效率及施工质量。
