TCVN 4054:2005: Vietnam’s Road Design Standard for Smooth Trucking

Mr. Ba, a seasoned rice truck driver in Hoai Duc district, vividly remembers his first day with a new truck. His joy was short-lived as the pothole-ridden road leading to the warehouse filled him with worry. “A new truck on a road like this will be ruined!”, he thought. Fortunately, after consulting a civil engineer, he learned about TCVN 4054:2005 – the guiding principle for road design, ensuring smoother and more durable rides for vehicles.

What is TCVN 4054:2005?

TCVN 4054:2005 is the Vietnamese standard for “Road Design Requirements,” issued in 2005. This standard specifies technical requirements for road design, ensuring traffic safety and facilitating the transportation of goods and passengers.

Why is TCVN 4054:2005 Important?

• Safety First: TCVN 4054:2005 sets standards for curve radius, slope, visibility, etc., minimizing traffic accidents, especially for heavy trucks.
• Protecting Your Vehicle: Standard-compliant roads ensure smooth vehicle operation, reducing damage and extending the lifespan of vehicles.
• Enhanced Transportation Efficiency: Well-maintained roads shorten travel time, save fuel, and reduce operating costs for drivers.

Key Points in TCVN 4054:2005

1. Road Surface Requirements

• Smoothness: The road surface must be smooth and even, ensuring a comfortable ride without vibrations.
• Cross Slope: The cross slope of the road surface must be appropriately designed to prevent vehicles from tilting, especially when cornering.
• Friction Coefficient: The road surface must have a sufficiently high friction coefficient to ensure vehicle grip, especially in rainy or wet conditions.

2. Road Width Requirements

• Lane Width: Lane width must be sufficient for vehicles to move comfortably and avoid collisions with other vehicles.
• Shoulder Width: Shoulders must be wide enough for vehicles to safely park when necessary.

3. Visibility Requirements

• Sight Distance: Sight distance must be sufficient for drivers to observe obstacles and react in time.
• Visibility at Intersections: Visibility at intersections must be ensured, allowing drivers to easily observe other vehicles and avoid collisions.

TCVN 4054:2005 and its Anecdotes

Not everyone is familiar with TCVN 4054:2005. Take the story of Mr. Tuan, a construction material truck driver in Long Bien district. Due to neglecting the height restriction under the bridge indicated on the sign (as per TCVN 4054:2005), he drove in and got stuck. This incident caused traffic congestion and brought Mr. Tuan considerable trouble.
