通过室内拉拔试验和剪切试验对SBS改性沥青、橡胶沥青、SBS改性乳化沥青和F型桥面专用防水材料用于桥面防水粘结层的路用性能进行研究,并采用拉拔仪和剪切仪对桥面防水层施工质量进行现场检测。室内试验结果表明:橡胶沥青和SBS改性乳化沥青路用性能良好,4种材料用于桥面防水粘结层时路用性能的综合排序为橡胶沥青〉SBS改性乳化沥青〉SBS改性沥青〉F型防水粘结材料;现场拉拔测试结果与室内小试件拉拔试验结果吻合度较好,表明可以采用室内小试件试验结果来预测和监控现场施工质量。
This paper studies road performance of SBS modified asphalt, rubber asphalt, SBS modified emulsified asphalt and F type deck specific waterproof materials used for waterproof bonding layer on the deck via indoor tensile test and shear test, and conducts site detection of construction quality of waterproof layer on the deck by means of tensile tester and shear instrument. The results of indoor tests show that rubber asphalt and SBS modified asphalt exhibit perfect road performance, comprehensive ranking of road performance of 4 materials used for waterproof bonding layer on the deck is rubber asphalt 〉 SBS modified emulsified asphalt 〉 SBS modified asphalt 〉 F type waterproof bonding materials; the result of on - site tensile test well coincide the result of tensile test of indoor small samples, showing that the test result of indoor small samples can be adopted to forecast and monitor construction quality on site.
