摘要
针对桥面防水粘结层材料路用性能衰减过快的问题,选择工程中常用的3种材料,在分别确定最佳用量的基础上,对比分析不同材料路用性能对温度、水和荷载的耐受性。结果表明:3种材料抗剪性能对温度的耐受性相差不大,温度对防水粘结层材料抗剪强度影响显著;SBS改性沥青抗剪性能对水的耐受性最好,而SBR改性乳化沥青最差;3种材料抗剪性能对荷载的耐受性相差不大。
Aiming at the fast attenuation of pavement performance of waterproof bonding layer on the bridge deck,three kinds of commonly used engineering materials are selected to compare and analyze the tolerance of their pavement performance on temperature,water and load respectively based on their respective optimal dosage.The results show that the tolerance of the three kinds of materials to temperature on the shear resistance performance has little difference,the temperature affects the shear strength of waterproof bonding layer material significantly;the tolerance of SBS modified asphalt to water on shear resistance performance is the best and the SBR modified emulsified asphalt is the worst;the tolerance of the three materials to load on shear resistance performance has little difference.
