1 6TH ANNUAL 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 lbs./foot Various Connections (Pins, Bolts, Interlocking) Very Durable 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 – linear feet/truckload vs 120 linear feet of concrete barrier Speed – Deployment speeds of up 1000’/hour Ease of movement in the workzone Durability – year useful life vs 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 Traffic Work Zone

13 Typical Deployments Traffic

14 Special Deployments - Movable Direction of Traffic Work Zone

15 Considerations Deflection – Steel barrier has less mass than concrete – Vendors have different anchoring requirements for various workzone configurations – 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!!
