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. More importantly, leaking fluids from automobiles in parking lots tend to ruin asphalt too.
When the right sealant is not used to treat asphalt, oxidation occurs, and it dries out the asphalt binder. When this happens, the pavement loses its flexibility and will begin to crack. When the ultraviolet rays from the sun harden and dry out the asphalt surface, oxidation happens. This raises the erosion and reduces the depth of the asphalt so that in only some years, the sidewalk needs 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. When the procedure starts, the damage has happened.
Applying a sealcoat shields the asphalt coating and reduces the negative impacts of oxidation and the extremes of the weather. This application will improve the overall look and increase the service life of the sidewalk significantly. Sealcoating keeps and will also restore the initial dark color of this asphalt to enhance the overall look of their house greatly.
In case you were to look at a cross-section of the untreated and treated asphalt, you will note the difference which 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 sunlight disintegrate the materials which bind down permitting the moisture to fill out the cracks and thus subjecting the vacant spaces called voids to contract and avoid breaking down the integrity of their 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 an excellent investment when upgrading pavements that require more repair or if employing new asphalt sidewalk 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.
