Microsurfacing trial at NH21 Ha Nam
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.
