| 摘 要： | 对PR和RA不同掺量的AC-20C和Sup-20两种级配的沥青混合料进行车辙试验，且应用灰色关联分析及统计学检验方法对车辙试验结果分析。结果表明马歇尔稳定度和马歇尔模数是影响车辙试验结果的主要因素；在PR或RA相同的条件下，级配由AC-20C转变为Sup-20时，对车辙试验结果影响较小。PR对混合料的改性性能优于RA。

| Abstract: | Wheel tracking tests are carried out against AC-20C and Sup-20 asphalt mixtures in different proportions of PR and RA and the test results are analyzed by grey correlation analysis and statistical test. The study result shows that Marshall stability and Marshall modulus are the main factors influencing the wheel tracking test result ; on the same conditions of PR or RA, the gradation changing from AC-20C to Sup-20 has minor effect on the wheel tracking test result. The modifying performance of PR is superior to RA. |
