How do you fix a hole in asphalt?

The roadways today seem to be getting worse with each passing day here in Texas and around the country. The cracks and potholes are endless it seems, and there really isn’t much we can do as citizens except drive carefully. City, County, State road crews have endless asphalt patching and repairs to do, but with the budget they have, they may never get caught up 100%.

When it comes to parking lots, private roads, and private driveways though, we are in charges of our asphalt patching and repairs. First though, you should understand what type of surface you can do asphalt patching on, and how. If it isn’t done correctly, it won’t stick, then you could end up with a bigger problem than you had.

Filling and repairing potholes as soon as they have started is important. If they aren’t, the holes get bigger, causing widespread pavement failure. This leads to damaged vehicles which can lead to lawsuits and insurance claims for the property owner. Asphalt patching and repairs can be done with either of the following two methods:

Cold-Patch Asphalt Patching

There are asphalt patching products on the market for cold-patch, that is affordable, easy, and best of all, durable and long lasting:

Step One – Clean the pothole out, removing debris and any big loose rocks.

Step Two – Pour the cold-patch material into the hole, half inch over the pothole surface, then spread and compact.

Step Three – Compact the cold-patch material with a tamper or you can drive back/forth over it to compact and level the asphalt patching material.

Water Activation Cold-Patch Asphalt Patching

Today, there is a water-activated pothole asphalt patching cold-patch technology. IT sets quickly to create a permanent pothole asphalt patching repair.

Step One  – Clean the pothole out, removing debris and any big loose rocks.

Step Two – Pour the cold-patch asphalt patching material in the pothole up to half an inch above the surface.

Step Three  – Spread a generous amount of water over the patch and allow it to penetrate into and soak the asphalt patching material. Water is what activates the curing mechanism within the cold-patch material.

Step Four– Compact the cold-patch material with a tamper or you can drive back/forth over it to compact and level the asphalt patching material.

What do you put under asphalt patches?

  • Add crushed, angular stone to the pothole, no less than 1-1/2 inch, but not more than 2 inches. With a steel tamping plate or any other heavy tool, pack the stone base.
  • Apply the asphalt patching material you’ve chosen, following the above steps and manufacturers instructions, leaving it at three-eighths of an inch above the surrounding area. Using a straight edge, check for an even surface, leveling out any high or low spots.
  • Do not cover the asphalt patching with an asphalt sealer. The patched area need air for curing. Between the asphalt patching and sealing, wait 30 days.

Even with expansive number of potholes and puddles, check if asphalt patching and repairs is possible before getting a new driveway, parking lot, or private roadway. An asphalt topcoat costs approximately one-third of a complete driveway redo. Almost any size crack can be done by patching asphalt with cement with the following steps:

  1. Clean debris and growths from the small cracks and holes .
  2. Hose the cracks and holes down and spray with weed killer.
  3. Use an asphalt patching product for crack of 3/8” or smaller and for cracks and holes larger then 3/8” use a concrete or vinyl concrete patching product. A quickset concrete product will work too.
  4. For deep cracks and large holes, fill with gravel up to 4 inches from the surface then fill with concrete.
  5. Tamp the concrete filled cracks and holes using a magnesium float and the finish up with a flat trowel to match the existing area level.
  6. After the asphalt patching is completed with the concrete, use a specialty cleaner to remove any spots then apply a sealant.

 How much does it cost to patch asphalt?

A professional asphalt patching and repair job can average anywhere from $900 and as high as $3,700, based on the size of the area to be patched and repaired.

What is the difference between asphalt and blacktop?

In general terms, asphalt refers to highways and public roadways and blacktop is referring to driveways and residential roads. While the terms are interchangeable, and blacktop is a form of asphalt, they are different.

  • Asphalt has two main ingredient, bitumen, and crushed stone. The bitumen is a black, or sticky material made from petroleum distillation that holds the crushed stones together.
  • Blacktop is made with the same ingredients, but a higher amount of stone. For it to be applied, it must be heated up to 300 degrees.

After being heated, both asphalt and blacktop are pre-mixed then poured into the area needed. Asphalt provides a smooth quiet surface, making it popular in neighborhoods. Asphalt is ready to drive on in 2 days while blacktop must cure for 4 to 5 days depending on the heat.
