We have already demonstrated that electromagmetic wave interference method can determine the packing conditions of drainage pavement by introducing a vector diagram. But a packing definition does not completely correspond to only one condition. That might bring some ambiguities on the diagram. Numerical simulations have shown that not serious but small ambiguities occur on the diagram. We also carried out measurements on actual roads, one for fresh pavement and the other for the pavement of one year old. Packing transition has been observed in a couple of months range on fresh pavement. However, on the pavement of one year old, where various degrees of packings exist, the significant transition has not been observed in a month range. This simultaneously shows that the method is reproductive.
