摘要/Abstract

摘要： 为了研究泥土对集料与沥青之间黏附性的影响,选取了3种不同岩性的碎石和2种不同塑性指数的泥土,在室内进行水煮沥青与粗集料的黏附性试验。试验结果表明,碎石表面的含泥量大小与泥土的塑性指数对沥青与集料的黏附能力影响显著,且煮沸时间长短影响黏附性分级,而抗剥落剂的长期有效性也值得进一步研究。

关键词: 粗集料, 黏附等级, 含泥量

Abstract: The objective of this study is to investigate the influence of clay coatings left on aggregate on adhesion of the asphalt and coarse aggregate by the boiling test,using three different coarse aggregates and two soil with different plasticity index.The test results indicate that clay dosage and plasticity index of the coarse aggregate influence the adhesion of the asphalt and coarse aggregate significantly.At the same time,the adhering grade is affected by the boiling time.Also,it is worth to continue to study the longtime validity of the asphalt anti-stripping agent.

Key words: coarse aggregate, adhesion grade, clay dosage
