Investment in asphalt paving does not end with the completion of the installation job. Proper maintenance will ensure the paving remains in full service condition for users to enjoy year-through. If you are going to provide maintenance, make sure it is done properly as incorrect maintenance normally causes more harm to asphalt paving than none at all. Here are some basic maintenance guidelines that can help slacken the pace at which your asphalt paving will call for complete resurfacing or replacement, allowing you to derive maximum service from it.

Apply seal coating

Over time, the oil binder that helps keep layers of asphalt material held together will deteriorate due to numerous factors, such as prolonged exposure to sunshine and ponded water. The oil binder usually provides a protective seal that moderates infiltration of water, which if allowed to settle underneath the surface of the asphalt surface, will damage the subgrade. When oil spots begin to show on the surface of your asphalt paving, or it starts losing its initial dark color, you should reseal the paving before any extensive damage can happen. Even though seal coating won't stop cracks from emerging and do not improve the strength of the asphalt paving, it will minimise the deleterious effects of sunlight and other weather elements, and it will help keep the pavement compacted for longer.

Use crack sealing

Regardless of how well asphalt paving is installed, cracking is bound to arise at some time. The main reason why you should seal cracks immediately is because they are trouble spots when water is allowed to find its way inside them. Crack sealing can be done by either using a spray nozzle or an injection nozzle. Applying the crack sealants using a spray nozzle is the more economical technique since it leaves behind a thick band of the sealants centered above the crack. The best method, however, is to use an injection nozzle that allows the sealing products to penetrate slightly beneath the surface of the paving to provide a more long-lasting seal coating. 

Patch up the rest

If the cracks on an asphalt paving have significantly broadened or have already created potholes, you will need to patch them up. Even if significant wear has occurred, it may be possible to remove and replace the affected areas without necessarily resurfacing or replacing the entire asphalt paving. In most cases, patching may be required where prolonged ponding of water or unfavorable soil conditions have intensified the problem.
