摘　　要：采用改性沥青稳定剂防止改性沥青离析以提升SBS改性沥青防水卷材热老化后低温柔性和质量损失,通过试验筛选出改性沥青稳定剂的最佳种类、掺量和使用条件;采用SBS与APP复配技术以提高SBS改性沥青防水卷材热老化后低温柔性和质量损失,通过试验确定出最佳掺量;采用加筋聚酯胎增强SBS改性沥青防水卷材,以提高SBS改性沥青防水卷材热老化后拉力保持率、延伸率保持率和尺寸变化率。In order to improve the low-temperature flexibility and quality loss of SBS modified asphalt waterproofing membrane after heat aging,the modified asphalt stabilizer was used to prevent the segregation of modified asphalt,and the optimal type,dosage and use conditions of modified asphalt stabilizer were screened out through experiments.The combination technology of SBS and APP was used to improve the low-tempera-ture flexibility and quality loss of SBS modified asphalt waterproofing membrane after heat aging,and the opti-mal dosage was determined by experiment.Reinforced polyester tires were used to strengthen the SBS modified asphalt waterproofing membrane to improve the tensile retention,elongation retention and size change rate of SBS modified asphalt waterproofing membrane after heat aging.
