When we think of winter and anchoring to asphalt, two distinct topics come to mind:  (1) the effect of winter on installed anchors, and (2) the effect of weather on the process of installation.

  1. Fortunately, anchoring installations using our BoltHold anchors and our recommended adhesive-grouts are not impacted by cold weather, rain, snow or ice.  There is, however, one aspect that merits consideration and that is mechanical snow plowing for installations where the attached items are removed for the winter.  One typical case is where speed bumps are removed to allow fast snow removal.

    The concern is that a snow plow can hit the head of the anchor or a bolt that was threaded into the anchor to protect the thread from dirt and corrosion.  The solution is to recess the anchor by 2-3mm (0.1") so that the head is truly flush or just below the surface of the asphalt.  This can only be done during the anchor's installation, preferably using our Flattener. As far as protecting the thread, use a low profile rounded head bolt, or a set screw, or our ThreadGuard.

  2. Installing the anchors during the winter requires special considerations.  Please refer to an earlier blog entry here.
