摘要
分析抗车辙沥青混合料车辙试验的评价指标,提出由动稳定度推算综合稳定指数的计算公式。通过对AC-20C和SUP-20型两种沥青混合料掺加不同掺量的改性剂（PR和RA）进行车辙试验,应用灰色关联分析及F检验方法得知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,并得出级配由AC-20C转化为SUP-20时,对车辙试验结果影响较小的研究结论。
Based on the analysis of evaluation index on rutting tests of rutting resistance of asphalt mixture,the formula projected by the dynamic stability for calculating the comprehensive stability index is put forward.By way of rutting test for asphalt mixture type of AC-20C and SUP-20 mixing two different contents of modifying agent（PR and RA）,It is known that Marshall stability and Marshall modulus are the main factor affecting the rutting test by utilized gray relational analysis and statistical testing methods.When the gradation changed from AC-20C into SUP-20,the result of less affection on the rutting is obtained.
