Patch for asphalt 8 - Free Download
Use asphalt patch in a bag to fill a shallow pothole. Cold patch asphalt can work well if installed correctly. My blacktop drive is in fairly decent shape except for a few potholes. I am confident that I can do the asphalt patch repairs but wonder what can one do to make a permanent patch?
The highway crews in my area don't seem to have much luck as potholes seem to reappear in a short amount of time. Is cold patch asphalt the best material to use to fill holes in blacktop? What is the best way to repair cracks?
Patching holes in asphalt surfaces can be done successfully, if you have some time, purchase the right material, and a use a few basic tools. Many potholes tend to form in cold weather after a period of snow and ice is followed by a thaw. The water that thaws and soaks into the cracks of the asphalt refreezes at night. The ice expands as it freezes and blows apart the asphalt. Thousands of potholes can appear overnight and spread like an epidemic. Highway crews often work in adverse weather and dangerous traffic conditions.
It's unrealistic to expect perfect results when many holes need to be filled in a short amount of time. The best asphalt patch is hot mix asphalt. To get the absolute best repair of the pothole, the asphalt next to the pothole must be reheated and blended into the patching material. Watch these two amazing video to see how it's done.
The first video shows a larger machine, but the second video is a smaller man-powered machine you roll around! The key to successful pothole repair is preparation, and the use of the right materials.
As I said before, the best material to use for pothole repair is traditional hot mix asphalt. This product is made at plants that mix liquid asphalt, sand and different sized gravel into a mix that flows while it is hot. As it cools, the liquid asphalt hardens producing a very durable surface.
It's not easy, nor is it feasible, for you to buy hot mix asphalt. If you buy a small amount, by the time you get home it will not be workable. Cold patch is very DIY friendly. It comes in managable bags and you can patch holes as small as 2 inches by 2 inches.
You need to use a new and improved cold asphalt patching compound. It's absolutely the next best thing. Do you need to patch your asphalt? For many years, asphalt plants have made a cold patch asphalt that was intended for temporary patching purposes. This older material was difficult to work with and the asphalt binder that coated the stone particles often stripped off in a relatively short amount of time. When the asphalt disappeared, so did the patch. Fortunately, there have been some major advancements in cold patch asphalt technology.
Yes, there are newer cold patch asphalt materials that contain polymers. The polymers increase adhesion so the cold patch sticks to the old asphalt. New synthetic polymer adhesive chemicals are now added to the asphalt that allow the cold asphalt patching products to produce permanent repairs when installed correctly.
They're easy to use and very affordable. The new cold patch asphalt mixes flow readily when you use them. If you've ever seen a video of how lava creeps across the land in Hawaii, you'll know how this cold patch material flows from the bag. Thicker patches of cold asphalt are not necessarily better as they possibly will require longer periods of time to fully cure and harden.
The best way to install cold patch is to make sure the bottom of the pothole is slightly larger than the top. This dovetail shape helps hold the patch in place much like a filling in your tooth.
Long lasting repairs require some minimal effort on your part. The key is the shape of the hole before it is repaired. This is how dentists ensure a tooth filling doesn't fall out. By making the bottom of the hole bigger than the top, you create a dovetail joint much like cabinet makers have used to securely join two pieces of wood. The best cold patch chisels are ones about 1.
I'd use a cordless hammer demolition hammer to get the job done in seconds. This is a great cordless demolition hammer that will accept a wider chisel to trim the sides of an asphalt pothole. Use a chisel to create vertical faces on the sides of the hole that extend down to the solid base material or down to a previous layer of solid asphalt. Be sure to remove any loose pieces of old pavement and any dust. The preferred thickness of the patching compound is approximately 2 inches.
If you have a deep hole to repair, install angular crushed gravel in the bottom of the hole. Compact this gravel well before you add the cold patch material. Yes, you should use a hand tamper to compact the asphalt patch. Coat the bottom of the tamper with diesel fuel to prevent the cold patch from sticking to it. Tamping tools used for compacting gravel or the cold patch material are easy to handle.
They're normally an 8x8-inch plate of steel. Just make sure you don't tamp your foot! Take your time to compact it very well with a steel tamper before you add the cold asphalt patching compounds. Once the gravel is compacted, add the cold asphalt so that it slightly above the surrounding pavement, level it and use a flat steel tamper to compact it. Some of the new cold asphalt products maintain that they can be driven on immediately. This is true, but as each day passes, they get harder and harder.
Avoid concentrated loads on fresh patches. Kickstands from bicycles and motorcycles can create dimples. Automobile tires that turn while the car is stationary can also damage a brand new patch.
No, do not apply asphalt sealer to the cold patch. The sealer will prevent the patch from getting hard. Once you have completed your pothole repairs, wait a long time before you think about sealing it. Some places say to wait at least 30 days before you apply a liquid blacktop sealer.
A sealer that is applied over a fresh patch will cut off the necessary supply of air to the cold asphalt. The cold patch needs the air to cure. If this happens, the patch can remain somewhat soft for a long period of time.
If you're going to seal a cold patch, be sure the sealer has silica sand in it to fill the voids between the small cold patch aggregate. I repair asphalt cracks using an epoxy that comes in a caulking tube. I press small stones and scatter sand in the fresh epoxy to make the crack match the asphalt. Copyright Tim Carter. As you wait for the cold patch to fully cure, take your time and clean out any cracks in the driveway area.
Wait one week and then fill the crack to the top. Place small stones and sand in the fresh epoxy to disguise the crack. This two-step process will help to create a smooth surface at each crack location.
Here's the fresh epoxy completely hidden by sand and stones pressed into the goo. Watch this video, but don't use the black goo in the caulk tube. It's an amazing epoxy that comes in a caulk tube and is made for concrete.
The epoxy you should use is demonstrated in the video below. What kind of liquid asphalt repair or sealer will put in a perfectly level finish that won't peel in the heat of the summer?

Cold patch asphalt can work well if installed correctly. If you're going to seal a cold patch, be sure the sealer has silica sand in it to fill the voids between the small cold patch aggregate. Wait one week and then fill the crack to the top. My question is will the pea gravel prevent the asphalt from settling and curing or is there something else I should place in the hole prior to the asphalt? And in this case, as I was doing it, I found out that we had a rather massive root right in the middle of it, so we had to get the root out as well. If you want instant gratification, then rip out what he did and do it right. It's unrealistic to expect perfect results when many holes need to be filled in a short amount of time.
