| Abstract: | The deflection criterion of the void under slab of the cement concrete pavement is studied on the basis of the results of several void detective methods in the experimental road.The deflection criterion for determining the slabs with voids is put forward by the slab corner deflection together with the difference of the slab corner deflection under certain assurance rate,which provides a simple and practical method to determine the presence of voids under concrete pavement slabs for the contractors. |
