摘要
Abstract
In-situ hot regeneration of asphalt pavement has the advantages of being fast,convenient and environmentally friendly,and has been widely used in road maintenance in some provinces in China in recent years.However,engineering practice has shown that the road surface after geothermal regeneration is directly used as a road surface layer,and its durability is generally low,and diseases such as white,flying particles,and pits are prone to occur on the road surface.Directly adding an ultra-thin cover on the basis of in-situ thermal regeneration can give full play to the environmental protection and convenience advantages of in-situ thermal regeneration,and can also use the ultra-thin cover as a protective layer to delay the performance degradation of the in-situ thermal regeneration surface layer and extend road service life.Through optimizing the process of in-place hot recycling and optimizing the mix ratio of the asphalt mixture for the supermaster overlay,an effective combination of in-place hot recycling and ultra-thin overlay is achieved.Long-term follow-up observation shows that it has good road performance.关键词
