How it installs
Drill a hole with a 1-1/2" (SDS MAX) bit, as deep as the anchor (10″), using a hammer drill.
Clean the hole: brush, blow, brush, blow.
Fill the hole with EPX2 or EPX3 adhesive. The adhesive calculator tells you how much.
Insert the anchor until it sits flush with the pavement.
Wait for the adhesive to cure (follow its cure time; longer in the cold), then bolt your post down.
About this anchor
The SP58 is a heavy duty asphalt anchor rated at 5,000 lbs. pull (at 3" asphalt thickness). The 10" long anchor is designed to mount speed bumps and kerbs directly to asphalt surfaces.
The anchor incorporates a 5/8"-11 UNC (coarse) female thread. The thread of the bolt inside the anchor should not exceed 4". The anchor installations requires a 1.5" hole 10" deep and the use of our EPX2 or EPEX3. A 2" welded washer at the top of the anchor prevents the anchor from dropping below the surface. The SP58 anchors are mounted flush with the surface of the roadway, so that attached devices such as speed bumps can be removed without leaving dangerous screws or protrusions on the roadway.
The SP58-58 is a set of 6 anchors, each pre-installed with a bolt and a washer.

Guide loads come from the low end of our test results, including hot pavement up to 120°F, for short-duration loads on anchors installed in 3″ asphalt. The side guide load is where the anchor starts to shift, not where it fails. They are guidance, not a certified rating. How we test

Questions
EPX3 or EPX2?
EPX3 is the better adhesive in every way and works in cold weather. EPX2 is an anchoring cement whose advantage is cost; use it at 45°F and above. We recommend EPX3 when it's typically below 45°F near you this time of year, and EPX2 otherwise.
Do I need the CG40 caulk gun?
Only if you don't already have a high-leverage or electric caulk gun. EPX3 needs a high-thrust gun to dispense.
