中文摘要:
      针对混凝土桥桥面铺装防水黏结层材料的合理选择问题,采用能表征其真实工作状态的路用性能测试方法,对4种常用的防水黏结层材料进行了路用性能测试,并结合经济指标,利用混合型多指标灰靶决策模型对桥面铺装防水黏结层材料进行了优选.结果表明:温度和水是影响防水黏结层材料黏结强度的重要因素,二者耦合作用时,影响更为显著;防水黏结层材料的设置可以显著提高铺装结构的疲劳寿命,使用SBS改性沥青的组合结构抗疲劳性能最优;SBS改性沥青同步碎石防水黏结层材料的灰靶决策综合效用最优,推荐其作为混凝土桥桥面铺装防水黏结层材料.
英文摘要:
      Aiming at the reasonable selection of waterproof adhesive materials for bridge deck pavement, the road performance of four kinds of materials was tested, and then analyzed by the grey target theory combining with the economic performance. The results show that temperature and water are important factors which influence the bonding performance of waterproof adhesive layer, and the effect is much more significant when the coupling effect of the two factors. The setting of waterproof adhesive materials can significantly improve the fatigue life of pavement structure, and the combination structure of SBS modified asphalt is the best. The SBS modified asphalt and synchronous gravel waterproof adhesive materials are the best grey target option, and it is recommended as a concrete bridge deck pavement waterproof adhesive materials.
