Recovery treatment method and application of silicone adhesive for caulking of failure pavement

The invention discloses a recovery treatment method and application of a silicone adhesive for caulking of a failure pavement. The recovery treatment method of the silicone adhesive for caulking of the failure pavement sequentially comprises the steps of: mechanical crushing, magnetic separation crushing, fine grinding, chemical modification, drying, nanometer grinding and the like. Recovered waste rubber powder can be used as a reinforcing filler of the silicone adhesive for pavement caulking, on one hand, the value of waste solid waste is greatly exerted, and the problem of environmental pollution caused by joint cleaning waste is solved; on the other hand, the prepared silicone adhesive is excellent in performance in various aspects and meets the requirements of related technical standards. 本发明公开了一种失效道面嵌缝用硅酮密封胶回收处理方法及应用，该失效道面嵌缝用硅酮密封胶胶回收处理方法按顺序包括机械破碎、磁选粉碎、精细研磨、化学改性、干燥、纳米研磨等步骤。本发明回收得到的废胶粉可以作为道面嵌缝用硅酮胶的补强填料，一方面大幅发挥了废弃固体废料的价值，解决了清缝废料带来的环境污染问题；另一方面制得的硅酮胶各方面性能优异，符合相关技术标准的要求。
