Abstract: In view of the present situation that there is no evaluation standard for the technical status of steel bridge deck paving system in the current standards, the inspection data and maintenance history of the paving layers of typical steel bridges in Anhui province over the years have been collected. Four indicators, that is, damage index, driving quality index, rutting depth index and skid resistance index of steel bridge paving system in Anhui province were put forward by mathematical statistics regression and expert scoring method. Finally, the comprehensive evaluation index, that is, the performance index of the pavement layer, was put forward according to the weight of each single index assigned by the corresponding experts. The fact shows that the evaluation standard of the technology status of steel bridge paving system fills the vacancy of the evaluation of steel deck paving condition, and lays a foundation for subsequent maintenance decision of pavement layer.
