Research & Application of Cold Patch Asphalt Materials of Roads in Plateau Areas
By analyzing the working mechanism of the cold patch asphalt materials,two types of cold patch agents were chosen for indoor mix design.The determined cold patch asphalt material was applied in plateau environments.After on-site paving,repair effect testing and compared with indoor experiments,the applicable requirements and the scope were proposed.Based on this,the design concept of cold patch asphalt materials was further optimized to provide a scientific basis for the implementation in plateau areas.
