Vehicle Barriers          Back to War / Back Home

Thanks to Lisa for sending this one!

How many times have you wondered how strong those concrete barriers are that you see in front of military base entrances?

From time to time someone asks me what the concrete barriers are in front of controlled and secure buildings. When I tell them that the barriers will stop traffic, even trucks, from approaching the secure building I usually get a look of disbelief. I've been looking for some footage like this to prove my point.

In this test, the following parameters were used.  

    Truck = 65,000 lbs.
  
            Speed = 50 mph
  
            Kinetic Energy = 5.5 MILLION ft. lbs.
