Often used to construct driveways, macadam is a mixture of gravel or crushed rock. A thin layer of hot asphalt covers these stones. Macadam is a popular choice because it offers a wide variety of colour choices and provides extra traction during the icy winter months. Removing oil spills from macadam will protect the driveway from future damage caused by automobile oils.

Things you need
- Kitty litter
- Garbage bag
- 2 gallons warm water
- 1/2 cup grease fighting liquid dish soap
- Plastic bucket
- Plastic scrub brush
Pour kitty litter directly over the oil stain. Allow it to remain for several hours. The kitty litter will soak up any remaining oil. Scoop up and dispose of the kitty litter in a garbage bag.
Mix 2 gallons warm water and 1/2 cup grease-fighting liquid dish soap in a plastic bucket. The dish soap will be strong enough to remove the oil stains yet mild enough to avoid damaging the asphalt overlay and the gravel below.
Dip a plastic scrub brush into the mixture and work it into the oil stain. Continue to work the mixture into the stain until you completely remove it.
Rinse the soapy water mixture away with hot water.
