摘　　要：目前的粘层强度试验不能反映粘层的真实强度,鉴于此,先采用车辙仪碾压模拟道路实际运行环境,然后用拉拔、剪切试验测定车辙碾压后粘层的实际强度,并与车辙疲劳前粘层的强度进行对比。试验证明:该方法能真实地反映粘层强度,较目前常用的试验方法更为科学。At present the tack coat strength test can not really reflect the strength of tack coat.Given this,the rut instrument is used to simulate the running environment of highway,then the true strength is measured by the pull-out test and the shear test,and the true strength after the rutting fatigue is made a comparison with the strength measured by the routine test method.The test shows that this test method can really reflect the strength of the tack coat and more scientific than the routine test method.
