The Deterioration of Asphalt Pavement and its Causes
Factors that cause deterioration in pavement include: 1. Water. Over time and especially without proper maintenance water penetrates the asphalt, washes out the base underneath it, causing it to crack, break down and collapse. You should know that water is a critical material in the sealcoating process. 2.

What Is Oxidation, and Why Should it Matter to You?
Oxidation is simply the exposure of your pavement (or anything, really) to oxygen. Exposure to oxygen alters a material's physical characteristics, and different materials react differently. Iron, for example, rusts; exposing wine to air can cause it to lose its freshness and change color. A similar process takes place with asphalt pavement.
