Testing and Technical Information

 

Walls, Railings, Vehicular Barriers

 

At ReCon, we have done the testing and analysis required to support engineers that utilize ReCon in their critical infrastructure projects. We encourage wall design engineers to reach out to ReCon and request the data and tools that will assist them. Some of the information available includes:

Did You Know!!!

 

Pedestrian Railings

  • The ReCon 39” Deep Top Block with a Pedestrian Railing attached meets the overturning requirements of the IBC.  A GREAT solution, avoiding the need to mechanically fasten multiple courses of block and / or pouring concrete into hollow blocks

Vehicular Barriers

  • The ReCon Vehicular Barrier System can meet both the IBC 6000 # and the AASHTO TL-1 13,500 # Impact Load.

Frictional Grid Connections and 100% Coverage!

  • The ReCon Frictional Grid Connection meets the most stringent performance specifications for block to grid connection AND provides 100% grid coverage (as opposed to 25% or 50%).

Base Course Sliding and the Importance of a Flat BASE Block!

  • ReCon has tested “SLIDING” of its BASE Block on a crushed stone leveling pad and of its MIDDLE Block on the same crushed stone leveling pad. The results are significantly better when using the BASE Block.  Thus, always use a ReCon BASE Block for the first course (unless the leveling pad is concrete).  Some large block systems offer a “hollow block” with no smooth bottom base block.  In that situation, it would be critical that any design with such a system calculate sliding based on actual test data and NOT on the default value for sliding between concrete and crushed stone!
