Abstract

This paper presents the technical requirements and construction quality of the UHPC composite coating, which has been applied to the Thang Long bridge deck repair project at the end of 2020. The results show that the coating quality using up to 2,000 m3 UHPC, equivalent to 28,000 m2 of bridge deck, is higher than design requirements.
