On the other hand , the results of asphalt four components analysis experiments indicate that using the ratio of resin and aspartames to evaluate the asphalt adhesion is reasonable and sound . at the same time , the author makes use of rectangular reference frame to analyze the correlation between the asphalt four components and the adhesion ; and it can be concluded that the rectangular area of the asphalt four components in rectangular reference frame has good relations with the asphalt adhesion
通过对沥青的四组分分析，试验结果表明：采用胶质与沥青质的比值来评价沥青的粘附性是可行的；同时，提出利用矩形坐标系来分析沥青的四组分和粘附性之间的内在联系，结果表明：矩形坐标系下沥青四组分的四边形面积与其粘附性有相当好的相关性。
