摘　　要：机场道面密封材料的弹性恢复特性对道面防水密封效果具有重要影响。通过测试不同密封胶样品在不同试验条件下的弹性恢复率,比较了它们的弹性恢复性能。结果表明硅酮密封胶在不同条件下都具有极好的弹性恢复率,双组分聚硫也有相对较好的弹性恢复性能。在高温多雨地区的机场混凝土道面接缝,推荐采用硅酮密封胶或双组分聚硫密封胶。Elastic recovery of joint sealant for airport concrete runway is important to its waterproofing. Elastic recovery of different sealants was measured and compared. Test result indicates that silicone sealant has excellent elastic recovery under different conditions, and the two-component polysulfide sealant has relatively higher elastic recovery. Silicone sealant and two-component polysulfide sealant are recommended to airport concrete runway joints in hot and rainy areas.
