Method for evaluating adhesion of aggregate and asphalt

The invention provides a method for evaluating the adhesion of aggregate and asphalt. The method is characterized by comprising the following steps: S1, preparing four groups of same basic to-be-tested samples from the asphalt and the aggregate; s2, respectively carrying out freeze thawing, damp heat and aging treatment on three groups of basic to-be-tested samples to respectively obtain a to-be-tested sample I, a to-be-tested sample II and a to-be-tested sample III; s3, carrying out a bonding tension test to obtain a displacement-tension curve; s4, determining a displacement-tension area according to the displacement-tension curve; s5, calculating an adhesion coefficient R according to the displacement-tension area; and S6, evaluating the adhesion of the asphalt and the aggregate according to the adhesion coefficient R. By means of the method, the adhesiveness of the asphalt and the aggregate in different environments can be evaluated. 本发明提供的一种集料与沥青的粘附性评价方法，其特征在于：包括以下步骤：S1.采用沥青和集料制作四组相同的基础待测试样；S2.对其中三组基础待测试样
