Types of Asphalt Deterioration

The weathering of asphalt presents itself in two main ways; oxidation and raveling. As the pavement cures, the sun's ultra-violet rays harden and dry out the asphalt surface in a process known as oxidation. Raveling is when the asphalt surface becomes dry and brittle and small stones break loose from the surface.

How Does Heat Affect Asphalt? - Arnold Asphalt

Oxidation. Oxidation weakens the entire structure of the asphalt, causing the surface to become brittle. UV radiation from sunlight causes a chemical reaction where the light oils combine into heavier oils which reduces the number of binding oils in the asphalt. As oxidation progresses, cracking and/or raveling becomes more prevalent.
