摘　　要：采用法国标准高模量沥青混合料级配曲线EME14,基于内插法将EME14各筛孔通过率转化为中国标准下各筛孔通过率,开展中国标准下的马歇尔试验、车辙试验、动态模量试验和四点弯曲疲劳试验,根据试验结果提出了中国标准高模量沥青混合料HMAM-13路用性能建议标准。试验结果表明:中国标准下高模量沥青混合料沥青膜厚度最小值不宜小于8.4μm,推荐的沥青膜厚度为8.8~10.0μm;旋转压实试件和马歇尔试件空隙率在3%~6%之间;动稳定度建议不小于3500次/mm;15℃、10 Hz和45℃、10 Hz动态模量数值应分别不低于14000 MPa和1200 MPa;在温度为15℃±0.5℃、加载频率为10 Hz±0.1 Hz、控制应变为250με的试验条件下,高模量沥青混合料疲劳寿命不应小于106次。The French standard high modulus asphalt mixture grading curve EME14is adopted,and the passing rate of each sieve hole of EME14is converted into the passing rate of each sieve hole under the Chinese standard by using the interpolation method.The Marshall test,rutting test,dynamic modulus and four point bending fatigue test under the Chinese standard are carried out.Based on the test results,the recommended standard for pavement performance of Chinese standard high modulus asphalt mixture HMAM-13is proposed.The test results show that the minimum asphalt film thickness of high modulus asphalt mixture should not be less than 8.4μm,and the recommended asphalt film thickness should be 8.8~10.0μm.The porosity of graded rotary compaction specimen and Marshall specimen is between 3%and 6%.The required value of dynamic stability shall not be less than 3500times/mm.The dynamic modulus with 15℃,10Hz and 45℃,10Hz shall not be less than 14000MPa and 1200MPa respectively.Under the test conditions of temperature 15℃±0.5℃,loading frequency 10 Hz±0.1 Hz and control strain 250με,the fatigue life of high modulus asphalt mixture should not be less than 106 times.
