Winter can be hard on asphalt pavement. Melting snow and rain gets into cracks where it freezes and expands causing the cracks to get even bigger. Water can also get under the asphalt and drain away the ground underneath the pavement – this leads to the fracturing of the asphalt and the creation of pot holes. Winter temperatures are typically too cold in many regions to pour a hot pavement mix – outside temperature should be at least 50 degrees Fahrenheit for the paving mix to bond well with the existing asphalt pavement, but you can temporarily repair potholes and large cracks with a cold patch pavement mix. Here is how you can use a cold patch mix to keep your roads, driveways, and parking lots usable during the winter.
What You Will Need:
- Cold Patch Asphalt
Preparing Cracks and Pot Holes
One of the nice things about using a cold patch asphalt mix to fill cracks and pot holes is that you don't have to spend a lot of time preparing the holes and cracks like you would if you were doing crack sealing or laying a hot pavement mix. In most cases, you simply shovel the cold patch into the area being repaired, pat it down, and move to the next spot. However, when the asphalt is cracking apart into little pieces, you should take the time to remove the pieces so you can completely fill the hole and keep it from spreading open even wider.
Laying the Cold Patch Asphalt
Cold patch asphalt typically comes in 50 pound bags that you can throw onto the back of a pick-up truck and cart around to different areas that need to be treated. Break open the bag by driving the spade end of the shovel into the bag to break the wrapping. Shovel or pour the cold patch into the hole. You want to completely fill up the hole until the cold patch mound rises up a couple of inches above the pavement.
Tamping the Cold Patch
You will need to push the cold patch down into the hole or crack to make sure it completely fills the empty void. For small repairs, you can use a hand-held tamper tool to pound the cold patch down into the opening. For larger holes, place a plywood sheet down over the cold patch and drive back and forth over with your pick-up truck or other vehicle to push the cold patch into position.
Cracks and pot holes can cause a lot of damage to vehicles, and can end up destroying your asphalt pavement if they are not treated quickly once they appear. If you are not sure you can do the cold patch work yourself, call a professional asphalt paving company like Star Paving to do it for you.Share
