-½” lag bolts 5” long with lead shields or equivalent anchor
-(3 units per 4’ speed bump, 4 units per 6’ speed bump)
-½” flat washer, narrow type 1.25” outside diameter
2.04.02.Tools
-½” carbide tip drill bit for pilot holes
-¾” (typically for ½” lag bolts) carbide drill bit for re-drilling the holes for installation of the lead shields or as required per equivalent anchors

create a required size of the gutter
-Using ½” carbide tip drill bit, drill pilot installation holes 3.5” deep into the
concrete surface, using installation holes in the speed bumps as
guidelines
-Using ¾” (or other size required per equivalent anchoring system) re-drill the
holes 3.5” deep for the lead shields
-Insert the lead shields into the installation holes
-Reposition the speed bumps over the installation holes with the installed shields
-Bolt the speed bumps to the installation surface with the lag bolts with a flat
washer
- Maintenance
Rubber speed bumps shall be monitored and maintained by responsible party.
The following shall be examined:
-Security of installation hardware
-Condition of speed bump markings (painted stripes or other reflective devices installed on the speed bump)
Rubber speed bumps that are excessively worn shall be replaced with new or a reconditioned product.
- Appendixes
