【摘要】： 本文在归纳、总结国内外沥青与集料“粘附性”试验方法的基础上，运用灰关联方法，，分析了不同的沥青与集料“粘附性”试验方法与沥青混合料水稳性的相关关系，并提出了评价细集料与沥青粘附性的试验方法。通过研究沥青、集料的各种性质对粘附性的影响，提出了沥青与集料的粘附机理。分析了改性沥青与集料“粘附性”提高的原因。指出了影响沥青与集料的粘附性、沥青—集料系统抗水剥离能力、沥青混合料水稳性及沥青路面水破坏的因素。提出了为提高沥青路面抗水破坏能力而在材料选择方面的建议。研究了沥青与集料界面的相互作用规律。提出了提高沥青混合料强度的工艺。在以上研究结果的基础上，开发了长期性能较好、工艺简单、费用低的用于处理集料的抗剥落剂。这对于提高沥青路面抗水破坏能力具有一定的意义。
[Abstract]:On the basis of summarizing and summarizing the test methods of "adhesion" between asphalt and aggregate at home and abroad, this paper analyzes the relationship between different test methods of "adhesion" between asphalt and aggregate and the water stability of asphalt mixture by using the grey correlation method, and analyzes the relationship between the "adhesion" test method of asphalt and aggregate and the water stability of asphalt mixture. An experimental method for evaluating the adhesion of fine aggregate to asphalt is proposed. By studying the influence of asphalt and aggregate properties on adhesion, the adhesion mechanism between asphalt and aggregate was put forward. The reasons for the improvement of adhesion between modified asphalt and aggregate were analyzed. The factors affecting the adhesion between asphalt and aggregate, the ability of asphalt-aggregate system to resist water stripping, the water stability of asphalt mixture and the water damage of asphalt pavement are pointed out. In order to improve the anti-water damage ability of asphalt pavement, some suggestions on material selection are put forward. The interaction between asphalt and aggregate interface was studied. The technology of improving the strength of asphalt mixture is put forward. On the basis of the above research results, the anti-stripping agent with good long-term performance, simple process and low cost has been developed for the treatment of aggregate. This has a certain significance to improve the water damage resistance of asphalt pavement.
