Why is Asphalt Sealcoating Important?
Does your asphalt have numerous potholes or cracks even though it was done recently? 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 asphalt is not treated with the right sealant, oxidation occurs, and it dries out the asphalt binder. While this occurs, the sidewalk loses its versatility and will start to crack. Oxidation occurs when the ultraviolet rays of the sun harden and dry out the asphalt surface. This lowers the asphalt’s thickness and enhances the erosion so that in only a few years, the sidewalk has to be completely resurfaced.
The sidewalk starts to deteriorate fast as oxidation happens, then the chemicals, rain, and alternative pollutants seep into the cracks. Once the process begins, the damage has taken place.
Applying a sealcoat shields the asphalt coating and reduces the negative impacts of oxidation and the extremes of the weather. This application will extend the service life of the pavement greatly and also improve the overall appearance. Sealcoating keeps and will also restore the initial dark color of this asphalt to enhance the overall look of their house greatly.
You would note the difference which a sealcoat makes in case you were to observe a cross-section of the untreated and treated asphalt. 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 process progresses, the construction materials continue weakening until the big observable cracks and potholes develop.
Sealcoating helps in slowing down the breaking down of the asphalt binders’ binding qualities. The most essential convenience is its ability to avoid the premature wearing of the sidewalk. Sealcoating is an excellent investment when upgrading pavements that require more repair or if employing new asphalt sidewalk and parking lots.
When applying the sealcoating, a person sweeps the sidewalk surface, and all the observable cracks or potholes are filled and cleaned. The sealcoat is applied using a sprayer to make sure that the thickness is right.
