Insight To Help You Repair And Prevent Common Damage To Your Asphalt


Taking care of your asphalt driveway can keep it lasting a long time and will also maintain your home's exterior appearance. Natural weathering to your asphalt can begin to cause damage as soon as it is installed. Here are some tips to help you repair and prevent two of the most common types of asphalt damage.

Vehicle Fluid Damage

Your asphalt driveway can easily become exposed to fluids from vehicles and power tools, such as gasoline, diesel fuel, and also transmission and brake fluids. When this occurs, the fluids will begin to erode the asphalt's emulsion that binds the gravel together and gives the asphalt its structure. These types of fluids can be quite damaging to the surface of your asphalt. In fact, gasoline spilled upon your asphalt driveway can begin to break apart its surface and work down through three inches of asphalt within 48 hours.

If you don't clean up or repair a vehicle fluid spill, it will result in your asphalt breaking down and the damage increasing in size as it grows over the surface of your pavement. As soon as a spill occurs, sprinkle kitty litter over the fluids to soak up as much as possible. Sweep up and discard the kitty litter, and then use an asphalt degreaser cleaning solution with water and a long-handled scrub brush to remove the fluids and rinse it away. You can find this type of cleaner at most home improvement stores.

If the fluid has already begun to do damage to the asphalt, you will need to remove the damaged asphalt. You can complete this by cutting out the damaged asphalt with a gas powered saw blade. It is recommended to make the cut at least four inches around the outside of the visible damage to make sure you remove all the fluids. Adding this extra four inches ensure you get any and all vehicle fluids within the damaged area. Leaving any damaging vehicle fluids will cause additional damage later on that you will have to cut out and repair further. Cut completely through the depth of the asphalt, as you will need to replace its entire thickness.

When you remove the damaged cutout asphalt with a shovel, pry bar, or similar tools, take care you don't place the fluid-damaged asphalt onto any surrounding asphalt. Doing this can transfer the fluids onto your undamaged asphalt and cause additional damage. Place it directly into a trash bin or onto a heavy-duty tarp where you can transport it to the landfill. Prepare the edges of the cut-out asphalt with cold mix primer, applying the primer onto any areas where new asphalt will be applied onto existing asphalt.

Fill the void in your asphalt with bagged cold mix asphalt in layers, tamping down each layer before you add more material onto it for the next layer. You can use the end of a four-by-four wood post to compact the asphalt together, or buy or rent an asphalt hand tamp. Overfill the top of the repair and tamp it as level as possible. Place a section of plywood over the repair and drive a vehicle or truck over the plywood to compress and level the repair.

Weather and Sun Damage

Each day your asphalt is exposed to sun, wind, and freezing temperatures, the asphalt emulsion begins to dry out and become oxidized by the sun's harmful rays. Repairing any cracks that occur from this exposure is important, followed by protecting your asphalt with a seal coating layer. Watch the condition of your asphalt for signs of drying out and cracking, along with graying of its surface color. It is recommended to apply a seal coating every two to three years, depending on the climate and weather of your area.

Before you seal coat your asphalt, fill any cracks with an appropriate asphalt filler, which you can find at most home improvement stores. Use a liquid filler for small cracks, and a cold patch filler for wider cracks. You can use bagged cold patch asphalt to fill potholes and larger areas of damage. Be sure to remove all debris, vegetation, and loose particles from each crack or hole before filling it with new cold patch.

Having a driveway and parking lot paves on your property is an excellent way to ensure that you don't have to deal with mud, rocks, and tons of insects every time you leave the house or head back home.
