Geothermal Regeneration Technology in Highway Asphalt Pavement Maintenance
In this paper,the basic situation of highway asphalt pavement maintenance engineering is expounded.On this basis,the performance of the original asphalt pavement is analyzed through the test,etc.The existing problems mainly include the small proportion of coarse particle size aggregate.When designing the new mixture,add a coarse aggregate of 7.5％from 5 to 10 mm and 5％from 10 to 20 mm.In addition,it is found that adding additives can further improve the comprehensive mechanical properties of the mixture.Finally,the specific construction technology is analyzed from the construction preparation,road heating,road loosening,mixing,paving and rolling.Practice has proved that this technology can achieve the ideal effect,which is worth further promotion and use.
