Smart Ideas: Sealcoating Revisited

Why is Asphalt Sealcoating Important?

Does your asphalt have many cracks or potholes even though it was done in the recent past? Your asphalt parking might be impacted negatively by a weather with excess high temperatures in the summer, year-round humidity and a higher amount of rain. Additionally, the asphalt is also destroyed by leaking fluids from parked vehicles in parking lots.

When the right sealant is not used to treat asphalt, oxidation occurs, and it dries out the asphalt binder. While this occurs, the sidewalk loses its versatility and will start to crack. When the ultraviolet rays from the sun harden and dry out the asphalt surface, oxidation happens. This lowers the asphalt’s thickness and enhances the erosion so that in only a few years, the sidewalk has to be completely resurfaced.

As oxidation takes place, then the chemicals, rain, and other pollutants seep into the cracks, and the pavement begins to deteriorate rapidly. The damage has occurred once the process commences.

The asphalt surface is protected by applying a seal coat and reduces the harmful effects of weather extremes and oxidation. This application will extend the service life of the pavement greatly and also improve the overall appearance. Sealcoating preserves and will even restore the asphalt’s original dark color to improve the overall appearance of the property greatly.

In the event you were to look in a cross-section of asphalt which is untreated and that which is treated, you may note that the difference that a sealcoat makes. More to the enhanced physical appearance, the sealed pavement becomes a surface which is smoother to make the maintenance and sweeping smoother and less expensive. The most critical aspect is the capability of the asphalt pavement to withstand the damaging impacts of oil, gas and chemical salts.

Asphalt pavement is a combination of crushed stone referred to as aggregates and chemical binders that glue the mixture together. With time, the ultraviolet rays from the sun break down the binding materials enabling the moisture to fill the cracks and thus subjecting the empty spaces called voids to contract and expand breaking down the integrity of the pavements. When the pavement transforms to black to dull gray, this is notable. While this procedure continues, the construction materials go on weakening before the large observable potholes, and cracks grow.

Sealcoating prevents the binding qualities of the asphalt binders from breaking down fast. The most critical benefit is its ability to prevent the premature wearing of the pavement. Sealcoating is a great investment when updating pavements that need more repair or when applying new asphalt pavement and parking lots.

One sweeps the sidewalk surface and all the cracks or potholes which are visible are cleaned and filled when applying the sealcoating. The sealcoat is applied using a sprayer to make sure that the thickness is right.
