摘　　要：为研究温拌沥青混合料公称最大粒径对路面结构层合理厚度的影响,选取5种不同的混合料摊铺厚度,采用轮碾仪成型试件,进行了相应的路用性能试验和疲劳试验。研究表明:公称最大粒径与路面结构层摊铺厚度存在一个合理的比值,使得温拌沥青混合料各项性能达到最优。In order to study the influence of nominal maximum size of warm mix asphalt on the reasona- ble thickness of pavement structure layers, 5 different paving thickness of the mixture are selected, and the corresponding road performance test and fatigue test have been carried out by using molding apparatus of Lun grind specimen. The results show that： the nominal maximum size and the thickness of pavement structure layers have a reasonable ratio value, thus the performances of the warm mix asphalt become optimal.

关 键 词：温拌沥青混合料 公称最大粒径 结构层厚度路用性能 疲劳寿命
