The Importance of Asphalt Seal Coating

Asphalt is used for paving roads and driveways. Even though asphalt has great adhesive and waterproofing properties, it has its own flaws making it easy for salt and chemicals to penetrate the asphalt molecules.

Once this happens, asphalt will start losing its original properties such as binding and waterproofing. This will reduce the lifespan of the asphalt road and pavement.

The first sign of this is the change in color from black to brown then to color gray. Since asphalt is a by-product of the petroleum distillation process, it will dissolve in products derived from petroleum.

This is because all these products come from the same source making them have a natural affinity for each other. Therefore, they will rejoin when put together, making gasoline and oil dissolve asphalt as it contains similar chemicals.

Asphalt seal coating resists the other petroleum products like oil and gasoline, hence preventing them from rejoining with the asphalt molecules. This will help extend the life of the asphalt preventing any need of excessive patching and repairs.

Coating asphalt can help save a lot of time and money. To protect the asphalt, redo the coating every few years. Without the seal, you will have to replace asphalt since it deals with wear and tear on a regular basis.

Repaving a pavement or road is time-consuming and very expensive. Putting another sealant coat is less intensive work and saves you a lot of money in the long run.

The sunlight’s UV radiation can wear down the asphalt. After the asphalt wears down, it will start loosening down and aggregate that holds it together will start loosening and breaking, making the surface very rough. This will open up space for debris and dirt to enter into the asphalt spaces.

The coat will protect the road or pavement from the harsh and harmful radiation of the sun. Seal coating can double the life span of the asphalt keeping it strong and binding.
