Barrier Pins

1-1/2” Stabilization Pin

Many state DOT’s have adopted a design for a 1-1/2″ in diameter A36 stabilization pin for highway concrete barriers.  This steel pin is used to connect precast concrete barrier sections (often Jersey barriers or F-shape barriers) to asphalt or concrete surfaces. The idea is to improve their stability under impact and lateral loading. These pins have a ¼” thick A36 square plate welded to the top end at an 85-degree angle. If these pins are connecting the barrier to an asphalt surface, they are 48” in length and have a 2” cone point on the end being driven into the ground. If they are connecting the barrier to a concrete surface, the pins are 21-1/4” long and do not require a cone point. Although it may differ from state to state, these pins are typically hot-dip galvanized.
