| Abstract: | This study addresses the main diseases of old cement concrete pavement structures of the arterial highway in Xi＇an city. We study and evaluate the status quo of the old cement concrete pavement structures by using indicators such as pavement condition index （ PCI）, the bad board rate （ DBL） and load transfer coefficient of joints （ Kj ）. Combining the conclusions of economical analysis of different overlay structures for old cement concrete pavement, a typical overlay structure for old cement concrete pavement of the arterial highway in Xi＇an city is recommended. The plan is expected to be of great significance in improving design and quality of the reconstruction. |
