How to Install a Chain-Link Fence Post in Asphalt
When installing a chain link fence, there may be an area where posts for the chain link fence cross asphalt. If you already have a hammer drill, that will be fine for just a post or two. However, rent a small jackhammer for the project from a contractor rental outlet in your area if you need to install many chain link fence posts, since it will make the project take a lot less time.
Mark the area for the hole for the chain link fence post with chalk.
Place the tip of the jackhammer or hammer drill in the center of the hole. Cut through the asphalt. Widen by turning the bit until all of the asphalt in the area for the chain link fence post has been removed. Open an area big enough for the fence post digger to dig out the gravel and soil in the hole.
Use the cold chisel and rubber-headed hammer to remove small amounts of asphalt around the opening and create a clean cut to the hole. Undercut the hole by cutting more away from the bottom of the asphalt than the top.
Use the fence post digger to make the hole 2 feet deep.
Place the chain link fence post into the hole. Measure the amount of the chain link fence post that is above the asphalt surface. This measurement should be the same as all of the other chain link fence posts. Add or remove soil in the bottom of the hole until the chain link fence post is the same height above the ground as all other posts.
Mix the concrete mix according to package directions. Place newspaper on the surrounding asphalt to prevent spills of concrete on the asphalt. Pour concrete into the hole around the chain link fence post. Fill the hole to the edge of the bottom of the surrounding asphalt. There should be a space 2 to 4 inches from the top of the hole.
Place the level on the chain link fence post to ensure that it is plumb. Rotate the level all the way around the chain link fence post to ensure plumb on all sides. Hold in position until the concrete has firmed enough to hold the chain link fence post in position. Remove the newspaper.
Use a trowel to press the patch into the remaining space around the chain link fence post with asphalt cold patch. Feather the edge to smooth the asphalt cold patch over the existing asphalt.
