Abstract: According to the existing evaluation methods and theories, analysis and build the structural indexes of the damaged concrete pavement, appilying grey rational analysis documents the results of the other evaluation methods such as PCI, SRR ,and get some conclusions about the influences of the index factors, grey evaluation is significant to the practical engineering .

Key words: cement concrete pavement, distress evaluation, grey related degree.
