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。
Aiming at the problems of cracks, sinking and damage in semi-rigid base asphalt pavement in the alpine region, combined with the characteristics of semi-rigid materials and abundant solar energy resources in the alpine region, the paper presents the conservation methods of the heat-preservation bags with the advantages of energy saving, environmental protection and recyclable. Design test selected the best thermal insulation effect of the type of insulation bag. The results show that the curing method has a good heat insulation effect, can effectively inhibit the semi-rigid base temperature shrink and improve road quality.
