| 摘 要： | 采用ASTME1301-95标准，对amesCox＆Sons、COOPERSD IPC沥青混合料疲劳试验机进行了对比研究。沥青混合料初始弯曲劲度模量、疲劳寿命的试验结果及疲劳寿命的回归方程结果表明，上述三种四点弯曲疲劳试验机的试验结果具有较好的一致性：同时指出了应重视沥青混合料疲劳小梁试件的制作工艺与质量对疲劳试验结果的影响。

| Abstract: | The ASTM E1301-95 Standard is applied to carry out the comparisons of three types of fatigue testing machines for asphalt mixture including James Cox ＆ Sons, COOPER and IPC. The test results of asphalt mixture＇s initialflexuralstiffness, fatigue life and the regression equations of fatigue life indicate that the test resuits of those machines have good consistency. Meanwhile, it is emphasized that the quality of the asphalt mixture specimens is a key factor influencing the results of fatigue test. |
