摘　　要：针对高寒地区半刚性基层沥青路面出现裂缝、沉陷、残损等病害问题,结合半刚性材料的特性以及高寒地区丰富的太阳能资源,提出了具有节能环保、可循环使用等优点的保温袋养护方式,经设计试验选择了具有最佳保温效果的保温袋类型。结果表明,该养护方式具有良好的保温效果,能有效地抑制半刚性基层温缩,提高道路品质。Aimed at the cracks,subsidence,damage and other diseases on asphalt pavement with semi-rigid base in alpine region,a maintenance approach with the advantages of eco-friendly and recyclable was proposed considering the characteristics of semi-rigid materials and the abundant solar energy in alpine region.Isothermal bags were chosen based on the test results.Thanks to its best heat preservation effect,the maintenance approach with isothermal bags effectively inhibits the temperature shrinkage of the semi-rigid base and improves the road quality.
