为了探究橡胶改性沥青与集料之间的黏附性能，选取了石灰岩、玄武岩、花岗岩三种典型集料及其代表性氧化物组分，采用动态剪切流变试验、接触角试验分别计算橡胶改性沥青与集料的相互作用参数和表面能参数，并通过分子动力学模拟计算出其黏附功及剥落功，验证了试验结果的准确性和可靠性。结果表明：橡胶改性沥青与三种集料的界面交互作用大小顺序为：石灰岩>玄武岩>花岗岩；硅烷偶联剂能显著提高花岗岩集料的疏水性，从而增加了其与橡胶改性沥青的黏附性；分子动力学模拟得出剥落功与基于表面能计算的剥落功基本一致。研究结果为集料与橡胶改性沥青的黏附性表征提供参考。

In order to explore the adhesion properties between rubber modified asphalt and aggregates, three typical aggregates, limestone, basalt and granite, and their representative oxide components, were selected. Dynamic shear rheological test and contact angle test were used to calculate the interaction parameters and surface energy parameters of rubber modified asphalt and aggregates, and their adhesion work and peeling work were calculated through molecular dynamics simulation. The accuracy and reliability of the test results were verified. The results show that the order of interfacial interaction between rubber modified asphalt and the three aggregates is limestone >basalt > granite. Silane coupling agent can significantly improve the hydrophobicity of granite aggregate, thus increasing its adhesion to rubber modified asphalt. The results of molecular dynamics simulation are basically consistent with those calculated based on surface energy. The results provide reference for the characterization of adhesion between aggregates and rubber modified asphalt.
