The Importance of Asphalt Sealcoating
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 to this, leaking fluids from vehicles in parking lots tend to destroy asphalt also.
Oxidation takes place when asphalt is not treated with the ideal sealant, and it dries out the asphalt binder. The pavement loses it flexibility and will start cracking when this occurs. Oxidation occurs when the ultraviolet rays of the sun harden and dry out the asphalt surface. This raises the erosion and reduces the depth of the asphalt so that in only some years, the sidewalk needs to be completely resurfaced.
The sidewalk starts to deteriorate fast as oxidation happens, then the chemicals, rain, and alternative pollutants seep into the cracks. When the procedure starts, the damage has happened.
Applying a sealcoat protects the asphalt surface and lowers the damaging effects of oxidation and the extremes of weather. This application will improve the overall look and increase the service life of the sidewalk significantly. Sealcoating maintains and will even restore the original dark color of the asphalt to improve the general appearance of the property significantly.
You would note the difference which a sealcoat makes in case you were to observe a cross-section of the untreated and treated asphalt. In addition to the enhanced physical appearance, the sweeping and maintenance of sealed pavement becomes affordable and easier due to a smoother surface. The ability to resist the harmful effects of oil, gas and chemical salts is the most crucial part of the asphalt sidewalk.
A mixture of crushed stone called aggregates and chemical binders that glue the mixture together make up the asphalt. Over time, the sun’s ultraviolet rays break down the binding substances allowing the moisture to fill out the cracks and therefore subjecting the vacant spaces known as voids to contract and prevent breaking down the integrity of their pavements. This is largely seen when the sidewalk changes from black to dull gray. As this process goes on, the building materials go on weakening until the big visible potholes, and cracks develop.
Sealcoating helps in slowing down the breaking down of the asphalt binders’ binding qualities. The most critical benefit is its ability to prevent the premature wearing of the pavement. Sealcoating is an awesome investment when applying new asphalt sidewalk and parking lots or in upgrading pavements that need additional repair.
One sweeps the sidewalk surface and all the cracks or potholes which are visible are cleaned and filled when applying the sealcoating. To ensure the right thickness; the sealcoat is applied using a sprayer.
