1. Primary Barrier Types
Tire Walls (Tire Bundles)
Construction
- Stacked or banded tires
- Steel cable or conveyor belting tie-ins
- Positioned in 3–6 tire depths
Function
- Compress and absorb kinetic energy
- Reduce rebound forces
Use Areas
- Corner exits
- Low–medium speed impacts
- Temporary circuits
Advantages
- Low cost
- Easy replacement
- Good energy absorption
Limitations
- Can trap wheels
- Weather degradation
- Less consistent performance
Armco / Steel Guardrail
Construction
- Corrugated galvanized steel rails
- Mounted on steel posts
- Multiple layers for added strength
Function
- Deflect vehicle
- Spread impact load along barrier
Use Areas
- Track edges
- Long straights
- Perimeter fencing
Advantages
- Durable
- Cost-effective
- Proven standard (2000s era tracks)
Limitations
- Higher G-forces than modern systems
- Risk of vehicle snagging
Concrete Walls
Construction
- Reinforced concrete blocks or cast-in-place walls
Function
- Prevent vehicle penetration
- Provide maximum containment
Use Areas
- Pit lane walls
- Start/finish straight
- Ovals
- Spectator zones
Advantages
- Extremely strong
- Minimal maintenance
Limitations
- Very low energy absorption
- Hard impacts without secondary protection
