The first preventive maintenance trial of ADCo in Vietnam using Microsurfacing. ADCo/Tipco applied microsurfacing technique on HW21B, which witnesses intensive traffic, with speeds up to 80km/h, and heavy vehicles.  The road was used for 4 years with low macrotexture; such an issue can limit the speed of vehicles and negatively impact traffic safety, especially during rainy seasons. It was a good time to apply microsurfacing in order to prevent potential moisture damage and oxidation. After one layer of microsurfacing, the surface becomes homogeneous, with an average thickness of 10 mm, which can extend the service life of the road by a couple of years, restore skid resistance while protecting the pavement from moisture, and improve traffic safety.   Project name: Microsurfacing trial at NH21 Ha Nam Year: 2017 Location: Ha Nam Investors:  Ministry of Transport Contractors: Infrasol, FCC Phu Ly Bypass Consultant: ITST Scope of project: 2,100 m2 of preventive maintenance Construction section: Wearing course

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.   Project name: Thang Long Bridge Year: 2020 Location: Hanoi City Investors: PMU 2 Contractors: PHUONG THANH TRANSPORT CONSTRUCTION & INVESTMENT JOIN STOCK COMPANY Consultant: Viện Khoa học Công nghệ GTVT (ITST) Volume: 180 MT Scope of project: 27.000m2 surface layer with PMB III PG76 on UHPC.
