【摘要】：在我国经济加速发展和大力构建公共交通网络结构的社会背景下,我国城镇化的迅速扩张使得高速公路的建设展开了大规模的发展,这样也使得沥青路面得到了越来越广泛的应用。但在许多已建成的沥青路面所铺筑的道路中发现了由于日常养护工作不到位、路面早期微小病害处理不及时等各种原因导致的路面大型病害影响路面的正常使用和通车情况的问题,因此如何对沥青路面进行日常养护和早期病害修补应成为公共交通中越来越受关注和重视的部分。而目前市面上常见的沥青路面养护修补方法通常选用的原材料多为改性沥青或乳化沥青,养护过程中需进行不同工艺的加热操作,这样的养护方式不仅成本昂贵,并且对自然环境的影响较大,因此本文所研究的不饱和聚酯树脂沥青路面冷补材料具有十分重大的社会意义。不饱和聚酯树脂冷补材料是在常温下在不饱和聚酯中分别掺加促进常温固化的各种外加剂和支撑强度的粗、细集料,搅拌均匀后通过灌缝等形式对沥青路面一些早期病害进行养护维修的制品。在对大量相关文献研读的基础上,本文进行大量的基础实验和单因素对比实验,测定冷补材料在固化时间、流动性能及强度等方面的性能,对比不同配比所制成的冷补材料制品之间的性能,研究冷补材料各组分配比与相关性能之间的关系,确定不饱和聚酯树脂冷补材料的初步配比。在获得初步配比的基础上进一步通过正交试验研究各组分配比等影响因素对制品性能的影响大小,得到最优配比。
[Abstract]:With the rapid development of our economy and the construction of public transport network structure, the rapid expansion of urbanization in China has led to the large-scale development of highway construction. This also makes asphalt pavement more and more widely used. However, among the roads paved by many of the asphalt pavements that have been built, it has been found that the routine maintenance work is not in place, The problems caused by large-scale pavement diseases caused by the early minor diseases of pavement, such as failure to deal with them in time, have affected the normal use and opening of roads, Therefore, how to carry out daily maintenance and early repair of asphalt pavement should be paid more and more attention to in public transportation. At present, the common methods of asphalt pavement maintenance and repair are usually made of modified asphalt or emulsified asphalt, which requires heating operation of different processes in the process of maintenance, which is not only expensive, but also expensive. And it has a great influence on the natural environment, so it is of great social significance to study the unsaturated polyester resin asphalt pavement cold filling material in this paper. Unsaturated polyester resin cold supplement materials are coarse and fine aggregates which are added to unsaturated polyester at room temperature to promote curing at room temperature and supporting strength respectively. After mixing evenly, some early diseases of asphalt pavement are maintained and repaired by filling joint. Based on the study of a large number of related documents, a large number of basic experiments and single factor comparative experiments were carried out to determine the properties of cold supplementary materials in curing time, flow performance and strength, etc. The relationship between the distribution ratio of cold supplement materials and the relative properties was studied, and the initial ratio of unsaturated polyester resin cold supplement materials was determined by comparing the properties of cold supplementary materials made with different ratios. On the basis of obtaining the initial proportion, the influence of the distribution ratio of each group on the properties of the product was studied by orthogonal experiment, and the optimum proportion was obtained.
