Prior experience with this product has demonstrated that more adhesive is required than is stated on the manufacturers installation instructions.

CONSTRUCTION
[Replace entire section with the following:].
The contractor shall surface mount the delineators using a 2-part epoxy and/or anchor bolts per manufacturers specifications and per direction of City Maintenance staff and the City Representative.
The contractor shall procure all materials required and strictly follow each step of the manufacturers installation instructions (per installation video) to ensure proper tight bonding and anchoring to prevent the K-71 posts from uplifting after contact with vehicles.
Contractor shall use more than the manufacturer recommended amount of adhesive to ensure a proper bond/anchoring to the asphalt pavement. Contractor should have all equipment required for installation including but not limited to T-bar, manual adhesive dispenser, rotary hammer drill with 7/8-inch drill bit, compatible compressor with air hose, nozzle and fittings, a wire brush and a generator.
After anchor sleeve has been installed and while the adhesive is curing (before installation of the post), the contractor shall clean the pavement areas surrounding the hole to be clear of any spilled or residual adhesive that would prevent full contact of the K-71posts base with the pavement surface.
The installation includes but is not limited to the following steps. Contractor shall not skip any of these steps:
a. Mark areas for installation
b. Adjust drill depth setting to the length of the anchor sleeve. c. Drill 7/8 diameter hole to a depth of 5.9 to 6 MAXIMUM using a7/8 carbide bit. d. Using an air compressor, insert air tube nozzle to the bottom of hole and remove dust and debris.
e. Use a wire brush to clean hole to ensure proper adhesive bond. f. After using wire brush, use air compressor again to remove excess fine dust from the hole.
g. To help verify the depth of the drilled hole using an anchor sleeve, remove the plastic cap and insert a½ machine bolt as a grab bolt. h. While holding the grab bolt, lower the anchor sleeve into hole and ensure the top of the sleeve is1/8 to ¼ deep MAXIMUM below asphalt surface. If hole is drilled too deep, use small rocks or pebbles to adjust hole depth to proper height. i. When mixing adhesive from a new cartridge, ensure a proper adhesive mix by ejecting several ounces onto a disposable surface.
j. Insert nozzle into bottom of hole (not halfway) and inject resin while pulling back on the cartridge filling the hole and sleeve to about 50% of the height of the hole.
Insert reinforcement composite
screen into hole until flush or¼ below surface.
Reinsert nozzle into the hole and screen and continue to fill from the bottom to about 90% of the height of the hole.
k. Insert metal anchor bolt. NOTE: do not remove the plastic cap. The cap protects the anchor sleeve from filling with adhesive.

l. Lift and push anchor bolt repeatedly while inserting it in the hole to help work the adhesive in to the side walls. Adhesive should spill out the top of the hole, if not then enough adhesivewas
added. Please note: It is very important to progressively pull and push the sleeve when you are inserting it into the cavity. It forces the adhesive to saturate the dry asphalt if there is any fine drilling powder residue left on the walls.
m. Using a piece of carton or cloth, spread the adhesive around top of hole but clean off plastic cap and surrounding pavement of any spilled or residual adhesive. n. Let adhesive cure and remove plastic cap with a hole punch or screwdriver. o. Install K-71 post using the T-bar by ensuring the base anchor bolt is protruding from the base. Insert T-Bar socket onto hex bolt at base of K-71 post, align bolt with ground anchor. Once bolt is aligned with ground anchor, spin T-bar until post is snug and gripped into place.
