| 摘 要： | 为了提高机场混凝土道面封缝材料的工作性能和使用寿命,通过测试7种密封胶在4种试验条件下的弹性恢复率,分析比较了单(双)组分的聚硫、聚氨酯以及单组分的硅酮三大类密封胶的弹性恢复性能.通过35 d的试验测试表明,硅酮密封胶在不同条件下部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.

| Abstract: | In order to improve the performance and service life of joint sealant for airport concrete pavement,observations were carried out on elastic recovery of 7 sealants subjected to 4 weathering conditions,the elastic recovery of three generic types of sealants of nmnoeamponent and bicompnnent polysulfide,monocomponent and bicomponent polyurethane,and monocomponent silicone were analyzed and compared. The test observation over a period of 35 days indicates that the silicone sealant has excellent elastic recovery under the different conditions,and the bicomponent polysulfide sealants have relatively higher elastic recovery. It is recommended to use silicone sealant or bicomponent polysulfide sealant for airport concrete pavement joints in high temperature and pluvial region. |
