Maintaining your asphalt surface can help keep its surface durable, looking nice, and help it to last as long as possible. Here are the recommended steps to cleaning, repairing, and protecting your asphalt to keep it well maintained.
Clean Oil Spots
Vehicle oil spots left on your asphalt will begin to eat away at the asphalt's emulsion, doing more damage the longer they are left on the pavement. When you first notice an oil stain on your asphalt, you should clean it from the surface. Use a degreaser cleaner and a scrub brush with water to scrub and rinse it from the surface.
You can also use a mixture of trisodium phosphate, or TSP, combined with water to create a paste to clean an oil stain from the asphalt. Use a long-handled scrub brush to scrub the mixture into the oil spot, and let it remain for several minutes. Rinse the area with clean water to remove the paste and the oil spot.
If the stain still persists, you will need to use the following instructions to remove the oil spot damage.
Remove Oil Spot Damage
If you encounter an oil stain that has begun to penetrate into the top layer of asphalt and cause the emulsion to become pitted, you will need to burn the top layer of asphalt with your handheld torch. Next, scrape off the softened and oil-stained asphalt layer, and then replace the removed asphalt with some cold patch asphalt that you can buy bagged at most home improvement stores. Tamp it down with a hand tamp to make it level with the surrounding surfaces.
Oil stain damage that has begun to wear down into your asphalt more deeply will need to be cut from the asphalt with a circular concrete saw. Be sure to cut the entire thickness of asphalt from the pavement so you can remove all the oil stain damage. If you allow any of the oil to remain behind, it will continue to break down the asphalt and cause it to further deteriorate. Replace the entire removed section of pavement with cold patch asphalt. Be sure to compress the patch with a hand tamp or a compressor roller, depending on the size of your repair.
Apply Seal Coat Treatment
As your asphalt ages, the oils begin to oxidize and the asphalt begins to harden and eventually start to crack and show signs of wear. An application of seal coating on your asphalt surface slows the process of oxidation.
Once you have removed any oil stains and cleaned its surface, it is recommended to apply a seal coating onto your asphalt when its color has begun to lighten, cracks begin to form, and pieces of aggregate fall from the surface of the asphalt. You can hire a paving company like ASAP Asphalt Sealing & Paving Co. to apply a protective seal coating to your asphalt and prolong its life.Share
