As asphalt ages it turns from black to gray. The binder that holds the aggregate within the asphalt together is becoming brittle and deteriorating, known as raveling. This is due to the intensity of the UV rays beating down on the bare asphalt, causing the asphalt to weaken, making it brittle and dry which leads to cracking.

Cracks are a major cause of water penetration leading to erosion of the base rock underneath the driveway as well as under the garage.

Oil spots on a driveway are both an eyesore as well as extremely damaging to the integrity of the asphalt binder which holds the asphalt together. If oil spots are not treated, you will notice rapid deterioration.

Grass has an amazing ability, if not properly maintained, to grow over the edges of a driveway or parking lot and in many cases will eventually break through the asphalt. This causes the edges to crack and crumble.
