摘　　要：在泡沫沥青冷再生技术应用过程中,存在传统室内试验与实际施工不匹配的问题。通过室内试验,发现振动成型法比重型击实法成型试件的最佳干密度大、最佳含水量小更加合理,并得出振动成型法室内试验成型时间应大于120s。将振动成型法、静压法和旋转压实法三种试件试验结果进行比较,结果表明振动成型法试件密实度更好,强度更高。将试验结果与修正的Burgers模型建立联系,证明其混合料抗剪切变形能力更强,冷再生路面具有更好的抗车辙能力。It is found that the mismatch between the traditional laboratory test and the actual construction during the application of the foam asphalt cold recycling technology.The laboratory test results show that the vibration molding method has the better dry density and the better moisture content than the heavy compaction method.Then,vibration molding method's test molding time should be longer than 120s.Compared the results of using three test specimens,including vibration molding method,static pressure method and gyratory compaction method,the vibration molding method has better compactness and higher strength.Establishing contact with the modified Burgers model proves that the mixture has stronger shear resistance,which makes the cold recycling pavement have better rutting resistance.
