Precast Concrete Barriers in Canberra
Curved Barriers for Cornering & Redirection
Curved Precast Concrete Barriers
Engineered for Complex Alignments | Precast Concrete Solution – Serving Queanbeyan, ACT & NSW
Overview
Curved alignments present unique challenges in road safety barrier design. Traditional straight precast barriers require multiple short segments and sharp angular connections to approximate a curve, leading to:
- Increased number of joints (weak points)
- Higher installation time and costs
- Potential performance issues during vehicle impact
Precast Concrete Solution addresses these challenges with precision-engineered curved precast concrete barriers, offering continuous protection, compliance with AS/NZS 3845, and superior durability for roads, highways, and bridge approaches.
Why Use Curved Precast Barriers?
1. Seamless Alignment on Bends
Our curved barriers are manufactured to follow specific road geometry, ensuring a precise fit along curves, ramps, and roundabouts. This eliminates unnecessary joints and provides structural continuity.
2. Enhanced Vehicle Containment
Barriers on curves must redirect errant vehicles smoothly to reduce secondary crashes or rollovers. Our curved designs maintain the correct impact angle and comply with performance requirements under NCHRP 350 and MASH standards.
3. Reduced Joint Frequency
Every joint in a barrier system is a potential point of failure or maintenance. By supplying longer curved units, we minimise the number of connections, lowering both risk and long-term maintenance costs.
4. Accelerated Installation & Cost Efficiency
Fewer joints mean faster installation, less hardware, and reduced labour hours, which helps large-scale projects stay on schedule and within budget.
5. Improved Drainage and Aesthetics
Consistent curvature eliminates misaligned gaps that trap debris and water. This is particularly beneficial for urban streetscapes and architectural projects where aesthetics and functionality are critical.
Applications
Curved precast barriers are essential for projects where straight barriers are impractical or non-compliant:
- High-Speed Roads and Motorways – Safe redirection on sharp curves
- Bridge Approaches and Interchanges – Structural integration with minimal deflection
- Roundabouts and Tight Urban Roads – Space optimisation without sacrificing safety
- Industrial Sites and Perimeter Protection – Customisable for internal road networks
Technical Specifications
- Material: High-strength, steel-reinforced precast concrete
- Surface Finish: Smooth moulded finish (optional anti-graffiti coating)
- Radius Options: Available in multiple radii to match site-specific designs
- Barrier Lengths: Standard and custom lengths available for complex geometries
- Connection System: Positive pin and loop or bolted connections (compliant with AS/NZS 3845)
- Performance Testing:
- Designed for NCHRP 350 TL-3 and MASH criteria
- Dynamic deflection and impact angle tested for compliance
Available Radius Options
We offer curved barriers in standard radii to accommodate most project designs:
- 2.5 m Radius – For tight curves, roundabouts, and urban intersections
- 4.5 m Radius – For moderate bends and suburban roads
- 9 m Radius – For highway exits, large roundabouts, and bridge approaches
Custom radius manufacturing is also available upon request.
Applications
- Highways & Motorways – Continuous protection on sweeping curves
- Roundabouts & Intersections – Smooth geometry for traffic safety
- Bridge Approaches & Interchanges – Improved structural continuity
- Urban Streetscapes & Industrial Sites – Ideal where space and aesthetics matter
