摘要： 沥青稳定碎石基层疲劳性能直接影响柔性路面的使用寿命。为分析集料级配对沥青稳定碎石疲劳性能的影响，基于ATB-25和ATB-30两种类型的9种不同级 配的沥青稳定碎石疲劳试验数据，利用灰关联分析方法分析了不同集料级配参数对沥青稳定碎石疲劳性能影响的显著程度。通过回归分析的统计学方法，分别建 立灰关联分析方法得到的关键因素与沥青稳定碎石疲劳性能代表值之间的回归曲线关系。结果表明：在最佳沥青用量条件下，沥青稳定碎石混合料的2.36 mm筛孔 通过率、4.75 mm筛孔通过率、0.30~1.18 mm及0~0.30 mm筛孔区间集料质量分数是影响沥青稳定碎石疲劳性能的4个关键因素，当2.36 mm筛孔通过率为27%， 4.75 mm筛孔通过率为34%，0~0.30 mm筛孔区间集料质量分数为11%，0.30~1.18 mm筛孔区间集料质量分数为9%时，沥青稳定碎石混合料疲劳性能最佳。

Abstract: The fatigue performance of asphalt stabilized macadam directly affects the service life of flexible pavement. Based on the fatigue test data of 9 grades of asphalt stabilized macadam about ATB-25 and ATB-30, the influence of different aggregate gradation parameters on the fatigue performance of asphalt stabilized macadam was analyzed by grey relational analysis, in order to get the impact analysis of the different aggregate gradation parameters on the fatigue properties of asphalt stabilized macadam. Through the statistical method of regression analysis, the regression curves between the key factors obtained by grey correlation analysis method and the representative values of fatigue performance of asphalt stabilized macadam were established. The results show that the mixture passing rate of 2.36 mm sieve and 4.75 mm sieve, the aggregate mass fraction of 0.30~1.18 mm and the 0~0.30 mm sieve interval are the four key factors that affect the fatigue performance of asphalt stabilized macadam in the optimum asphalt aggregate ratio conditions. And the asphalt stabilized macadam mixture has the best fatigue performance under these conditions: the mixture passing rate of 2.36 mm sieve is 27%, the mixture passing rate of 4.75mm sieve is 34%, the aggregate mass fraction of 0~0.30 mm sieve interval is 11%, the aggregate mass fraction of 0.30~1.18 mm sieve interval is 9%.
