摘　　要：采用沥青路面分析仪(APA)对排水性沥青混合料(DA混合料)和SMA混合料进行标准条件和重载交通条件下的车辙试验,采用车辙深度指标分析DA混合料的抗车辙能力及其对加载水平、加载次数及温度的敏感性.结果表明:采用高黏度沥青、适当级配组成并予以充分压实,DA混合料的抗车辙能力可有效提高;DA混合料抗车辙能力对加载水平、加载次数以及温度的敏感性均低于SMA混合料.Whether drainage asphalt mixture（DA mixture） is applicable to heavy traffic load has been a main topic of much discussion. The rutting tests of DA mixture and SMA mixture under standard condition and heavy traffic load condition were carried out by using asphalt pavement analyzer（APA）. Indicator of rutting depth is used to evaluate rutting resistance of DA mixture and its sensitivity to load level, load numbers and temperature. The test results show that the rutting resistance of DA mixture could be improved effectively by using high viscosity asphalt, appropriate gradation sistance of DA mixture to load level, load numbers and certain compaction. The sensitivity of rutting re and temperature is lower than that of SMA mixture.
