Surface deterioration process begins soon after asphalt pavement has been exposed to the sun's ultraviolet rays and water penetration has occurred. Gas, oil and harmful chemicals play a role in this process as well. If pavement is left untreated, then the asphalt binder (glue) breaks down, changing the surface color from black to gray. Once this begins, the pavement is susceptible to further degradation, creating raveling and cracking which then erodes the base beneath the asphalt. This snowball effect will cause cracks to enlarge and potholes to form from base failure. In the New Hampshire climates, freeze/ thaw cycles along with water freezing and expanding, is an additional effect of surface and base erosion. Lastly, if neglected too long, the only option would be the costly expense of repaving. Fortunately, having your asphalt pavement seal coated

would not only protect the asphalt from these elements, but extend the life by 300%.
