Main Points Related to Parking Lot Sealcoating

Even if your asphalt pavement was recently redone, does it have a lot of cracks or potholes?
When asphalt is not properly sealed, oxidation occurs, causing the asphalt binder to dry out. When this happens, the pavement becomes less flexible and begins to crack. The sun’s ultraviolet rays harden and dry out the asphalt surface, which is known as oxidation. This accelerates corrosion and decreases asphalt thickness, requiring the pavement to be fully resurfaced in just a few years. Get the facts about Parking lot sealcoating near me
When oxidation occurs, rain, chemicals, and other contaminants seep through the cracks, speeding up the degradation of the pavement. The harm is done once the process begins.
The application of a sealcoat strengthens the asphalt’s surface and prevents the effects of oxidation and weather extremes. This application would significantly improve the pavement’s service life while also improving its overall appearance. Sealcoating maintains and also restores the dark colour of the asphalt, significantly improving the property’s overall appearance.
You can see the difference between treated and untreated asphalt by looking at a cross section.
In addition to looking better, the sealed pavement has a cleaner surface that makes sweeping and maintenance simpler and less expensive. The ability of the asphalt pavement to withstand the damaging effects of coal, oil, and chemical salts is the most critical factor.
Crushed stone (known as aggregates) and chemical binders bind the mixture together to form asphalt pavement. The sun’s ultraviolet rays deteriorate the binding materials over time, allowing moisture to fill in the cracks and causing the empty spaces (known as voids) to expand and contract, compromising the pavement’s integrity. When the pavement turns from black to a bland grey, this is most apparent. The binding materials degrade as the process progresses, resulting in large visible cracks and potholes.
Sealcoating prevents the asphalt binders’ adhesive properties from being broken down as easily. The ability to avoid premature pavement wear is the most significant advantage. Sealcoating is a wise investment when it comes to installing new asphalt pavement and parking lots, as well as updating those that are in need of minor repairs.
The surface of the pavement is washed first, and any apparent potholes or gaps are cleaned and filled. To ensure sufficient thickness, the sealcoat is applied with a sprayer. To make the survey more stable and non-slip, a high-quality sealcoat has the correct ratio of additives and fine sand as an aggregate. On highways and other high-traffic areas, a second coat is recommended to extend the pavement’s service life.
