Despite its excellent waterproofing and binding properties, asphalt has a few downsides related to its chemical structure. It combines a mixture of complex chemicals with a degree of instauration within their structure. This gives salts, weather, and chemicals to attack its molecular structure and damage it over time. As the molecules begin to disintegrate, the pavement loses its properties.
If you see asphalt changing its color, it’s the biggest sign of a quick change. Generally, the jet-black color turns grey or brown. It would be logical to say that roads exposed to damage need a protective coating to resist attacks or minimize them. This is where the seal coating comes in. Our asphalt paving contractors in Cary North Carolina use it to reduce the pavement damage, if not eliminate it.
