Special Site Considerations
A traffic control plan, in detail appropriate to the complexity of the work project, shall be
prepared and understood by all parties before Triton Barrier
®
is deployed in a work zone.
Some special site considerations are:
1. What is the intended speed at the site? The Triton Barrier
®
(TL-3) is capable of handling
impacts from vehicles up to 2000 kg [4400 lbs.] at speeds up to 100 km/h [62 mph] at
angles up to 25 degrees. The Triton Barrier
®
without pedestal (TL-2) is capable of
handling impacts from vehicles up to 2000 kg [4400lb] at 70 km/h [45 mph] and angles
up to 25 degrees.
LENGTH OF DEPLOYMENT WATER REQUIRED
30m [100 ft.] 8235 liters [2175 gal]
40m [130 ft.] 10,980 liters [2900 gal]
50m [165 ft.] 13,725 liters [3625 gal]
60m [195 ft.] 16,470 liters [4350 gal]
70m [230 ft.] 19,210 liters [5075 gal]
80m [260 ft.] 21,955 liters [5800 gal]
90m [295 ft.] 24,700 liters [6525 gal]
100m [330 ft.] 27,445 liters [7250 gal]
150m [490 ft.] 41,170 liters [10,875 gal]
200m [655 ft.] 54,890 liters [14,500 gal]
2. What is the length of deployment? A minimum length of Triton Barrier
®
is needed
upstream and downstream of area being shielded to ensure proper impact performance.
The minimum length will depend on the specified speed of the roadway. For 70 km/h [43
mph] the minimum overall length is 30 m [100’]. For 100 km/h [62 mph] the minimum
overall length is 60m [200’]. Refer to the Length of Need (LON) section of the Triton
Barrier
®
Product Description Manual for more information.
3. Is an End Treatment warranted for the exposed or flared end of Triton Barrier
®
? If so, an
appropriate End Treatment must be attached. Refer to the End Treatment section of this
Manual on Page 17.
4. What is the lateral offset? As a general rule, a roadside barrier shall be placed as far
from the traveled way as conditions permit. The barrier-to-hazard clearance to shield
rigid objects, equipment, embankments, drop-offs, work crews, etc. shall not be less
than the lateral deflection of the barrier. See Deflection Chart section of this Manual on
Page 25.
5. What foundation will the barrier be deployed on and what is its slope? Triton Barrier
®
may be deployed on various surfaces. Foundations other than clean asphalt may result
in varying lateral deflection for full design capacity impacts. See Deflection Chart section
of this Manual on Page 25. The existence of cross slopes greater than 5% or curbs may
create an untested effect on the impacting vehicle.
6. How will the barrier be deployed: (1) as a median barrier, (2) in a bidirectional traffic
situation, or (3) a road side application? Proper consideration must be given to Triton
Barrier
®
lateral deflection and End Treatment requirements to minimize the potential of
secondary impacts.
7. Can the water ballast be drained at the site? If not, provisions must be made to either
siphon out the water ballast or use a forklift to move full sections to a location where they
can be drained.
