【摘要】：在沥青路面的使用过程中，由于水的存在大大降低了路面的使用性能，目前水损害已经成为路面破坏的主要形式之一。引发这一形式的路面使用性能下降的根本原因是沥青与矿料的粘附性不足，而水是导致这一过程的诱因。评价沥青与矿料粘附性的方法有很多种，，这些方法各有其自身的优势及不足之处。本文基于对现有的沥青与集料的粘附性评价试验的归纳与总结，试图找到更为科学有效方法来判断沥青与集料粘附性的优劣。 通过对沥青材料及矿料的基本性质和粘附性产生原理的介绍，分析其对沥青混合料整体水稳定性的影响。认为沥青的化学性质和矿料表面纹理构造是影响混合料水稳定性的主要因素。 从产生粘附性的基本理论角度出发，分析沥青与矿料产生粘附效果时各类作用力的影响程度，以及当前常用的评价沥青与矿料粘附性的方法。结合分析沥青混合料水稳定性的试验方法，间接评价了沥青与矿料的粘附性。 在总结影响水稳定性和粘附性的基础上，提出了运用光电比色法试验评价沥青与矿料粘附性，分析了光电比色法的基本原理和方法步骤，测试三种矿料和不同改性沥青的粘附性，并与水煮法试验结果作对比，验证了光电比色法的可行性，同时也说明了光电比色法试验的优越性。
[Abstract]:In the use of asphalt pavement, water damage has become one of the main forms of pavement damage due to the existence of water greatly reduces the pavement performance. The main reason for the deterioration of pavement performance is the lack of adhesion between asphalt and aggregate, and water is the cause of this process. There are many methods to evaluate the adhesion of bitumen and aggregate, each of which has its own advantages and disadvantages. Based on the conclusion and summary of the existing asphalt and aggregate adhesion evaluation tests, this paper tries to find a more scientific and effective method to judge the adhesion between asphalt and aggregate. Based on the introduction of the basic properties of bituminous materials and mineral aggregate and the principle of its adhesion, the influence of asphalt mixture on the overall water stability of asphalt mixture is analyzed. It is considered that the chemical properties of asphalt and the texture structure of aggregate surface are the main factors affecting the water stability of mixture. From the point of view of the basic theory of producing adhesiveness, this paper analyzes the influence degree of various kinds of forces when asphalt and aggregate produce adhesion effect, as well as the commonly used methods to evaluate the adhesion of asphalt and mineral aggregate. Combined with the test method of analyzing the water stability of asphalt mixture, the adhesion between asphalt and aggregate is evaluated indirectly. On the basis of summing up the influence of water stability and adhesion, the paper puts forward the application of photoelectricity colorimetry to evaluate the adhesion of asphalt and mineral aggregate, and analyzes the basic principle and method steps of photoelectric colorimetric method. The adhesiveness of three kinds of mineral materials and different modified bitumen was tested, and compared with the results of boiling test, the feasibility of photoelectric colorimetric method was verified, and the superiority of photoelectric colorimetric test was also explained.
