THE CASE FOR SHALLOW
TWELVE INCHES INSTEAD OF A PIT. (AVBD 452)
AVBD 452 sits in a twelve-inch reinforced slab rather than a conventional pit. The tested configuration holds an M50 P1 rating under ASTM F2656-23 and is listed on the DoD Anti-Ram Vehicle Barrier List.
A 15,120-lb truck at 51.46 mph produced 0.45 ft of dynamic penetration and −0.75 ft static penetration. The product uses a direct-acting three-finger wedge with hydraulic, hybrid or electric drive options.
