【摘要】：近年来，河北省的公路桥梁建设得到了一定的发展，但由于车辆数量猛增及车辆重型化现象严重，，桥面铺装病害问题越来越突出并存在着安全隐患。针对桥面铺装的这些病害研发了高性能桥面铺装冷补沥青混合料，其可以在低温的环境下且不封闭交通的情况下对桥面铺装破损面进行快速有效的修补。本文首先对桥面铺装修补技术及路面冷补沥青混合料的路用性能进行了研究，结合国内外的研究现状，针对河北省桥面铺装的主要破坏类型进行了分析总结。然后，从混凝土简支T梁桥桥面铺装修补体系入手，运用ansys有限元分析软件分析了混凝土简支T梁桥的敏感位置、荷载最不利位置及修补结构模量对修补结果的影响等。之后，对冷补沥青混合料的原材料及试验方法进行了系统的研究并确定了冷补沥青混合料的组成成分，同时，通过正交试验方法确定出了冷补沥青混合料的最优组成方案，再通过反应型树脂对冷补沥青混合料进行进一步的优化最终得到高性能桥面铺装冷补沥青混合料。最后，对高性能冷补沥青混合料的制备工艺、施工工艺进行了阐述，对其社会效益及经济效益进行了分析。
[Abstract]:In recent years, highway and bridge construction in Hebei Province has been developed to a certain extent, but due to the rapid increase in the number of vehicles and heavy vehicles serious phenomenon. The problem of bridge deck pavement diseases is becoming more and more prominent and there are some potential safety problems. A high performance cold filled asphalt mixture for bridge deck pavement has been developed for these diseases. It can repair the damaged deck of bridge pavement in low temperature and without traffic closure. In this paper, the bridge deck pavement repair technology and pavement cold-filled asphalt mixture road performance were studied, combined with the domestic and foreign research status. The main failure types of bridge deck pavement in Hebei Province are analyzed and summarized. Then, the repair system of concrete simply supported T-beam bridge deck pavement is introduced. The ansys finite element analysis software is used to analyze the sensitive position of concrete simply supported T-beam bridge, the most unfavorable position of load and the influence of the modulus of the repaired structure on the repair results. The raw materials and test methods of cold filled asphalt mixture are studied systematically and the composition of cold supplementary asphalt mixture is determined. The optimum composition scheme of cold supplementary asphalt mixture is determined by orthogonal test method. Then through reactive resin to further optimize the cold filled asphalt mixture, finally get the high performance bridge deck pavement cold filled asphalt mixture. Finally, the preparation process of high performance cold supplementary asphalt mixture. The construction technology is expounded, and its social and economic benefits are analyzed.
