Description

Technical Field

[0001] The utility model relates to the technical field of road surface repair, in particular to a compacting device for cold regeneration of asphalt road surfaces. Background Art

[0002] Asphalt pavement is widely used due to its superior performance such as comfortable driving, low noise, easy mechanized construction, and convenient maintenance and repair. Compaction is an important part of asphalt pavement construction. The performance of compaction methods and equipment directly affects the compaction efficiency and the quality of asphalt pavement.
