Abstract: According to a lot of cold regeneration technology research literature, summarized the classification of the regeneration technology, as well as the advantages and applicability of all kinds of cold regeneration of cold regeneration technique. And emphatically studied the foamed asphalt cold regeneration, the emulsified asphalt cold regeneration, the two ash cold regeneration, the water stability of cold regeneration of mixture ratio design method. Evaluation method of old pavement materials, the dosage of the different kinds of cold regeneration of various materials and their properties, and the requirement of grading, the determination of optimum moisture content, as well as some specific research test method in common use, according to many literature obtained several kinds of cold recycled mixture ratio design of technical index requirements. Through induction and comparison, finally it is concluded that the difference and connection between different kinds of cold regeneration.
