【摘要】：道路预成形标线带是一种新型的路面标志标线材料,相比于目前使用十分广泛的涂料标线,它在路用性能尤其是清除涂改性能等方面表现出了自己独特的优势,但是相对于国外的广泛应用,其在国内目前还处于起步发展阶段使用较少,对其认识也不是很充分。本论文通过国内外资料的收集查阅总结分析,以及关于道路预成形标线带路用粘接性能的试验设计和分析,为道路预成形标线带未来在我国的广泛使用提供一定的理论支持。论文的创新工作主要体现在两个方面：首先,通过对国内外道路预成形标线带从生产成型到路面使用等方面的资料的收集总结分析,以及传统涂料标线的使用情况,将两者从分类、组成结构、施工成型方法、路用反光耐久性能、清除涂改性能、产品价格等方面进行系统的对比分析,进一步加深对道路预成形标线带的了解。通过对比发现：无论是在成型方法还是组成结构上道路预成形标线带均更加先进实用；施工方法上方便快捷,能节约更多人力物力以及施工周期；路用性能方面也有着较好的表现；在清除涂改性能方面相较于涂料标线更加方便实用,且效率高不伤及路面；但目前在产品价格方面要贵于大部分涂料标线产品。其次,论文对道路预成形标线带所采用的压敏胶黏剂与路面的粘接作用进行了理论分析和试验研究,指出：预成形标线带与路面粘接作用的形成机理复杂,是吸附、静电、扩散、机械结合等理论共同作用的结果。为研究其粘接性能,论文采用180°剥离试验方法,以剥离力的大小作为评价指标,分别对三种不同厂商的预成形标线带样品在不同表面状况和不同环境状况下的粘接性能进行了剥离试验分析,其中表面状况包括测试板材料的不同、粗糙度的不同以及清洁状况,环境状况包括温度和浸水的变化。试验中采用了水泥板和车辙板两种测试板来模拟实际水泥路面和沥青路面。试验结果表明：预成形标线带粘接性能与路面铺筑材料的关系密切,而传统粘接性能评价以钢板为介质,不论是在粘接机理、粘接性能以及粘接破坏方式上都与路面材料存在一定的区别；而且,路面粗糙度大小、清洁状况、不同的施工温度等,均对预成形标线带粘接性能有不同程度的影响,虽然粗糙度和温度一般不会影响到预成形标线带的使用,但表面的清洁状况却对粘接性能的发挥极为重要。此外,试验结果还证实：预成形标线带粘接性能对浸水条件不敏感,但温度的变化会导致粘接破坏类型的改变。
[Abstract]:Road pre-formed marking belt is a new type of pavement marking material. Compared with the widely used paint marking material, it shows its own unique advantages in road performance, especially in cleaning and modifying performance. However, compared with the extensive application abroad, it is still in the initial stage of development in our country, and it is not fully understood. This paper is based on the collection, summary and analysis of domestic and foreign data. And the experimental design and analysis on the adhesive performance of road pre-formed marking strip provide certain theoretical support for the future extensive use of road pre-formed marking strip in our country. The innovative work of this paper is mainly reflected in two aspects: first of all, Through the collection, summary and analysis of the data from production to pavement use of the road pre-formed marking belt at home and abroad, as well as the use of the traditional paint marking line, the paper classifies the two from the classification, composition structure, construction forming method, etc. Road reflective durability, removal and alteration performance, product price, etc., are systematically compared and analyzed. Through the comparison, it is found that the road pre-formed marking belt is more advanced and practical in both the forming method and the composition structure, and the construction method is convenient and fast. It can save more manpower and material resources as well as construction cycle; the road performance also has better performance; compared with paint marking, it is more convenient and practical than paint marking, and high efficiency does not harm the road surface; However, at present, the price of the products is more expensive than that of most paint marking products. Secondly, the paper makes theoretical analysis and experimental study on the bonding effect between the pressure-sensitive adhesive and the road surface used in the road pre-formed marking tape. It is pointed out that the formation mechanism of adhesion between preformed marking strip and road surface is complex, which is the result of the joint action of adsorption, static electricity, diffusion and mechanical combination. In order to study its adhesion performance, 180 掳peeling test method is adopted in this paper. Taking the peeling force as the evaluation index, the peeling performance of preformed strip samples from three different manufacturers under different surface conditions and different environmental conditions were analyzed respectively. The surface conditions include the different materials of the test board, the difference of the roughness and the cleanliness, Environmental conditions include changes in temperature and flooding. Cement and rut test plates are used to simulate actual cement and asphalt pavements. The test results show that the adhesive properties of preformed marking strips and pavement paving are obtained. The material is closely related, However, the traditional evaluation of adhesion performance is made of steel plate, which is different from the pavement material in terms of adhesion mechanism, adhesion performance and failure mode, and the roughness, cleanliness, construction temperature, etc. Although roughness and temperature generally do not affect the use of preformed tape, surface cleanliness is of great importance to the bonding performance. The experimental results also show that the adhesive properties of the preformed strip are not sensitive to the soaking condition, but the change of temperature will lead to the change of the type of bond failure.
