  1. 6THANNUAL CONFERENCE

  2. The Use of Temporary Steel Barriers in Construction Zones By Don Pyde Product Manager Trinity Highway Products

  3. What is Temporary Steel Barrier? Typically: • Rugged • Lightweight (When compared to concrete or water-filled barrier) • Galvanized Steel • Easy to move • Flexible applications

  4. Examples • Vulcan • Zoneguard • ArmorGuard • BarrierGuard 800

  5. Physical Characteristics • Galvanized Steel • Typically 32” Tall • Multiple Lengths – 13.5’ to 50’ • Weight typically 60-70 lbs./foot • Various Connections (Pins, Bolts, Interlocking) • Very Durable • 15-20 Year Useful Life

  6. Standards • NCHRP 350 • TL-3 (62mph) • TL-4 (large truck) • MASH • TL-3 (62mph) • TL-4 (large truck)

  7. Why use Temporary Steel Barrier? • Safety • Steel Barrier offers positive protection • Reduce Congestion • Steel Barrier allows for dynamic lane closures • Steel Barrier allows for rapid repositioning • Lower transport costs • 600-750 linear feet/truckload vs 120 linear feet of concrete barrier • Speed • Deployment speeds of up 1000’/hour • Ease of movement in the workzone • Durability • 15-20 year useful life vs. 5-10 with concrete

  8. Unique Features • Wheeled Barrier • Allows for positioning and movement by hand • Allows for towing laterally down the work zone.

  9. Unique Features • Gates - Easily create openings in medians or runs of temporary barrier

  10. Unique Features • Movable Barrier

  11. Applications • Highway and road construction zones • Fixed • Changing/Moving • Short Term or Off-Peak Traffic • Bridge Repair • Decks • Piers • Sign – Roadside structure repair • Median or Barrier Gate Openings • Emergency Crossovers

  12. Typical Deployments Work Zone Traffic

  13. Typical Deployments Traffic Traffic

  14. Special Deployments - Movable Direction of Traffic Direction of Traffic Work Zone

  15. Considerations • Deflection • Steel barrier has less mass than concrete • Vendors have different anchoring requirements for various workzoneconfigurations • Deflections range from 1” to 13’.

  16. Considerations • End Treatments • End treatments are required where a blunt-end hazard exists

  17. Steel Barrier Summary • Provides Safety for Workers • Mitigates congestion • Lightweight • Easy to move to and within the workzone • Can put 6 times as much on a truckload compared to concrete • Saves on costs!!
