Focusing on the development of rubber powder processing and applications of waster rubber,the key issues in rubber powder processing including normal temperature crushing and low temperature crushing were described,and the characteristics of devulcanization techniques such as physical devulcanization,mechano-chemical devulcanization and chemical devulcanization as well as bio-desulfurization were summarized. Moreover,the applications of rubber powders in modification of asphalt,blending with rubber and mixing with plastics were reviewed. It was necessary to gradually establish evaluation methods for stability of rubber powders and their products. The research directions of production and application of waste rubber powder were the related mechanism of manufacturing process for rubber powder,activation process for devulcanization and preparation process for reclaimed rubber,the submicroscopic structure of rubber powder/rubber blends and rubber powder/plastic blends,and the life prediction of rubber powder composite products。
