【摘要】：沥青混凝土路面出现裂缝,应及时进行密封修补,防止雨水及其他杂物沿裂缝进入路面结构层及路基,导致路面承载能力下降,加速路面局部或成片损坏。该论文主要借鉴国外密封胶产品的技术指标,针对寒冷地区公路的不同早期状况,采用不同的道路裂缝修补材料生产工艺技术,针对不同特点,研制道路裂缝修补密封材料。论文中提及的高性能道路修补材料的性能尤其是低温柔韧性(延度)以及粘接性优于现有的国内同类产品,与国外较好产品相当,尤其适用于我国东北地区的低温气候条件,而价格仅为国外同类产品的80%左右。根据吉林省气候特点,确定了区域灌缝材料技术标准,提出了裂缝宽度和刻槽宽度的计算方法。结合吉林省高速公路沥青路面所用灌缝材料的特点,首次提出了通过拉伸试验检验灌缝材料低温粘附性、延展性的试验方法和技术指标以及沥青路面灌缝胶溢出率试验方法。对灌缝工艺影响因素进行了研究,提出了新的沥青路面灌缝材料使用效果的评价指标,总结了试验段灌缝经验,编制了吉林省高速公路灌缝材料应用及施工技术指南。
[Abstract]:In order to prevent Rain Water and other sundries from entering the pavement structure and subgrade along the cracks, the bearing capacity of asphalt concrete pavement should be reduced and the local or damaged pavement should be accelerated. This paper mainly draws lessons from the technical index of foreign sealant products, according to the different early condition of highway in cold area, adopts different road crack repair material production technology, according to different characteristic, develops road crack repair sealing material. The properties of the high performance road repair materials mentioned in this paper, especially the low temperature flexibility (ductility) and adhesion, are superior to those of the domestic ones, and are comparable to those of the foreign ones, especially suitable for the low temperature climate conditions in the northeast of China. The price is only about 80% of similar products abroad. According to the climatic characteristics of Jilin Province, the technical standard of regional irrigation joint material is determined, and the calculation method of crack width and groove width is put forward. According to the characteristics of filling joint material used in asphalt pavement of Jilin Province, the test method and technical index of low temperature adhesion and ductility of filling joint material and the test method of asphalt pavement joint overflow rate are put forward through tensile test for the first time. This paper studies the influencing factors of filling joint technology, puts forward the evaluation index of the application effect of new asphalt pavement jointing material, summarizes the experience of filling joint in test section, and compiles the application and construction technical guide of filling joint material in Jilin Province expressway.
