Research on Maintenance Scheme of Steel Deck Pavement of Liede Bridge and Project Implementation
First,an analysis of the disease characteristics of the steel bridge deck pavement of Liede Bridge was con-ducted.Considering the current state of Liede Bridge steel bridge deck pavement,a research on the maintenance scheme for the steel bridge deck pavement of Liede Bridge was carried out,taking into account construction time and traffic passage.A maintenance scheme has been determined to retain the RA05 layer and renovate the SMA10.At the same time,a comparison of materials for the pavement layer of Liede Bridge has been made,using PG-100 high viscosity modified asphalt SMA10 as the upper layer of the pavement and PG-82 modified asphalt as the bond-ing layer.Secondly,the content and construction points of the PG-100 high viscosity modified asphalt SMA10 pavement maintenance scheme were introduced.Finally,the new pavement condition was continuously observed for one year,and the test results met the expected goals.The maintenance scheme for the steel bridge deck pavement of Liede Bridge provides a reference for similar projects.
