Thang Long Bridge
Innovative solution for Steel deck bridge.
The continuous serious damage of the SMA layer on the Thang Long Bridge since the completion of massive repair works in 2011 have left both MOT and Hanoi City in need of a total and permanent solution to upgrade the bridge surface. After a series of proposals and years of study, it was decided to harden the steel deck with UHPC (ultra-high performance concrete) with steel fiber and cover it with 4 cm of PMB III with super-high performance. After careful evaluation of mix design in the lab and validation after trial paving, the high performance with wider range of temperature application of PMB PG76 Colflex of ADCo was selected for the project. This product helps with the paving/compaction of the PMB asphalt layer, which can be executed under conditions of strong winds, high humidity, and low temperatures in winter; the project was completed in Dec 2020.
