Oxidation causes asphalt to fade and turn gray, especially if it is at least a few years old. Fresh asphalt generally has a rich black color, due to the element called bitumen, a tar-like substance used as binder that holds together the aggregates in asphalt mixes. With constant exposure to the sun, bitumen slowly evaporates, while leaving behind the aggregates. This gives asphalt a faded appearance and indicates it is becoming brittle as it dries out. Unfortunately, the fading is often uneven, which means that some sections might appear darker or lighter than others, making the surface of your asphalt look unsightly.
