With the rapid economic development of Vietnam, the highway system plays a critical role in transportation and regional connectivity. Currently, Vietnam’s highway network stretches over 2,000 km, connecting North to South and supporting logistics, trade, and mobility.
Major highways such as Ho Chi Minh City – Long Thanh – Dau Giay Expressway are already in operation, while others are under construction. Maintaining these highways requires professional cleaning solutions to ensure safety, efficiency, and long-term durability.
Why highway sweepers are essential
Highways constantly accumulate:
-
Dust
-
Sand
-
Debris
-
Tire residue
Unlike urban roads, highway cleaning requires:
-
High-speed operation
-
Large waste capacity
-
Continuous working capability
-
Minimal traffic disruption
Therefore, using specialized road sweepers is mandatory to maintain safety and operational efficiency.
