| 摘 要： | 现行评价集料与沥青粘附性好坏的水煮法主观性大，导致产生的误差大。采用4种试验方法分别对石灰岩、砂岩、花岗岩和玄武岩与沥青的粘附性进行试验，比较每种试验方法测得沥青剥落率的大小。试验表明，NAT法能较好评价沥青与集料的粘附性。

| Abstract: | The big subjectivity of current water boiling method for evaluating the adhesion between aggregate and asphalt causes big errors.This paper adopts four test methods to test the adhesion of limestone,sandstone,granite and basalt with asphalt respectively,and compares shell-off ratios of asphalt measured in various test methods.Test results show that the NAT Method can well evaluate the adhesion between asphalt and aggregate. |

| Keywords: | asphalt aggregate adhesion shell-off ratio |
