Abstract

In order to understand the main diseases of ERS steel bridge deck pavement system and further optimize the maintenance decision of ERS steel bridge deck pavement system, this paper judged the technical statuses of the EBCL layer, RA05 layer, and SMA layer of ERS steel bridge deck pavement system by means of the thermal imager, small-scale milling, and other technologies based on the bridge deck pavement maintenance project of Jiashao Bridge over the years. It was determined that the bridge deck pavement damage is mainly located in the SMA layer. Based on this, the rutting depth standard for maintenance and screening was clarified as 10mm. Two maintenance schemes were compared for the rutted section, and a better maintenance scheme was selected.
