Item Section Snowplowable Pavement Markers 1086 -3 Epoxy 1081 Use snowplowable pavement markers that are on the NCDOT APL . -3 CONSTRUCTION METHODS
Bond marker housings to the pavement with epoxy adhesive. Mechanically mix and dispense epoxy adhesives as required by the manufacturer's specifications. Place the markers immediately after the adhesive has been mixed and dispensed. Install snowplowable pavement marker castings into slots sawcut into the pavement. Make slots in the pavement to exactly duplicate the shape of the casting of the snowplowable pavement markers. If saw cutting, milling, or grooving operations are used, promptly remove all resulting debris from th e pavement surface. Install the marker housings within 7 calendar days after saw cutting , milling, or grooving the pavement. Remove and dispose of loose material from the slots by brushing, blow cleaning or vacuuming. Dry the slots before applying the epoxy adhesive. Install non- cast iron snowplowable pavement markers according to the manufacturer’s recommendations. Protect the non-cast iron snowplowable pavement markers until the epoxy has initially cured and is track free.
In th e event that a reflector is damaged, replace the damaged reflector by using adhesives and methods recommended by the manufacturer of the markers and approved by the Engineer. This work is considered incidental if damage occurs during the initial installation of the marker housings and maintenance of initial non -cast iron snowplowable markers specified in this section. This work will be paid for under the pay item for the type of reflector replacement if the damage occurred after the initial installation of the non -cast iron snowplowable pavement marker . If during reflector replacement it is discovered that the housing is missing or broken this will be paid as Non -Cast Iron Snowplowable Pavement Markers . Missing housings shall be replaced. Broken housings shall be removed and replaced. In both cases the slot for the housings shall be properly prepared prior to installing the new housing; patch the existing marker slots as directed by the Engineer and install the new marker approximately one foot before or after the patch . Removal of broken housings and preparation of slots will be considered incidental to the work of replacing housings .
Use properly refurbished snowplowable pavement marker housings as approved by the Engineer such that approved new reflectors can be installed inside the housings .
