Anchor Pins

In most cases barriers need to be anchored or pinned in place. The requirements defining when a barrier section must be anchored in place can vary depending upon the type of barrier (median, guard rail), the surface it is being used upon (concrete, asphalt, bridge deck), whether it is a temporary or permanent barrier, and the traffic speed on the road or highway it will be used on. The anchoring pin itself can come in many different sizes, materials, and configurations depending on the type of barrier and which state is specifying it. Terminology differs from state to state and this anchoring hardware may be called an anchor pin, a stabilization pin, or an anchor bolt, depending on which state’s drawings you are looking at.
