Your asphalt driveway provides a solid surface for your vehicles, but can also be on the receiving end of damaging fluids from vehicles and power tools. Because your asphalt driveway is made from a mixture of tar emulsion and gravel, many types of vehicle fluids, such as gasoline, oil, transmission and brake fluids can damage its surface and break down the emulsion causing its layers to deteriorate. Here are some tips to help you clean fluids stains and protect its surface so your asphalt pavement looks great and lasts as long as possible.
If you encounter a vehicle fluid stain that has just spilled onto the surface of your asphalt, it is important to clean it up and remove it as soon as possible. The longer the fluids are left to sit on the asphalt, the more damage they can do to the surface.
Sprinkle cat litter liberally onto the fluids and the stain to cover it completely. Let the cat litter sit on the fluids for several hours for the litter to soak up the vehicle fluids. Sweep up the litter with a broom and dust pan and toss it into the trash.
Next, clean off any remaining fluids as they can permeate into the cracks and crevices of the asphalt and continue doing damage. Apply an industrial strength degreaser cleaner onto the stained section. You can find this type of cleaner at most automotive shops and home improvement stores. Use a scrub brush to scrub at the degreaser until it creates suds, which will lift the fluid stain from the asphalt's surface.
Rinse the area thoroughly with your garden hose or a pressure washer. Be sure to rinse all the cleaning agent and residues fully off the side of the asphalt. Simply rinsing the bubbles and residue to a new spot on the asphalt will only transfer the damaging fluids.
If any vehicle fluids have been left to sit for a longer period of time and have begun to erode into your asphalt, you will need to remove the damaged portion. Use a circular saw with a masonry blade to cut around the area of damage and through the asphalt's thickness. Be sure to make cuts several inches outside the damage so you are sure to remove all the vehicle fluids.
Use a shovel and a pry bar to lift up and remove the damaged asphalt and dispose of it into the trash. If the damaged section is a large area, use the saw to cut the area into smaller sections for easier removal.
Now you can hire an asphalt company to fill the areas of damage or you can complete the repair yourself with bagged cold patch asphalt filler.Share
