9/22/2017 7 Comments The Scoop on Asphalt MaintenanceEvery asphalt parking lot eventually requires maintenance. Asphalt maintenance is similar to automobile maintenance and household repairs. If it is not completed in a timely manner, it will sabotage quality and reliability. So, don’t assume your asphalt parking lot will continue to prove reliable as time progresses. It will eventually reach a point where its integrity is compromised. Deteriorated asphalt might even prove hazardous to you, your employees, your clients, and others.
The bottom line is asphalt pavements have stresses that gradually produce defects. These stresses are caused by all sorts of stimuli from traffic to movements in the underlying below, holes, cracks etc. These defects must be pinpointed and repaired right away by proven asphalt maintenance professionals. Here’s exactly what to look for to determine if your property requires asphalt maintenance. Potholes: Potholes occur when the pavement is weak. Perhaps your asphalt parking lot has undulations that cause the back ends of trucks to smack down and form potholes. The asphalt surface might be too thin, allowing standing water to breach cracked spaces and send water into the base. This forces the asphalt to lift and form potholes. Drainage Issues: Pavement distress is often caused by the accumulation of moisture within the pavement structure. This is precisely why it is so important to maintain your lot’s drainage system. Eliminate all dirt and contaminants from the catch basin and pipes. This maintenance will empower your lot’s drainage system to function as designed. It will also help your finances as you won’t spend nearly as much on parking lot repairs and replacement. Have your drains inspected at least once per year? If a clog is identified, it must be cleaned right away. In certain instances, it might necessary to enhance or replace the current drainage system to ensure optimal functionality. Pavement Sealer: If new asphalt pavement isn’t treated, it will gradually break down when exposed to the elements. Everything from dripping oil and gas to the sun’s harsh rays and the pounding rain can damage asphalt. The best form of preventative maintenance for lots is pavement sealer. It is affordable and provides extensive protection that delays or eliminates prospective repairs. Ideally, asphalt maintenance resealing will occur a year after the new asphalt overlay is installed. It should then be performed every couple of years. Overlay: When asphalt becomes too thin or old to maintain its intended traffic load, an asphalt overlay is necessary. Asphalt that has become overly-thin or has reached the end of its lifespan will gradually develop potholes. Though asphalt overlay is somewhat expensive, it is absolutely worth the money. It makes your lot new again. Asphalt overlay thickness should be at least an inch in thickness for surfaces that are still sound. Potholes, sink holes, root damage, cracking and drainage issues must be tended to prior to the application of the overlay. The installation of curbing, water meters, valves and manhole drains must be raised for compatibility with the newly added asphalt overlay. Current asphalt that extends to the front of the entry doors, sidewalks and garages must be cut at least two feet to jive with the current flush. This also combats reversed slopes. In the end, the quality and reliability of the new asphalt overlay hinge on the level of preparation and repairs performed at the outset of the project. In many instances, all that is necessary prior to the overlaying is a thorough cleaning of the surface. Cracking: Those interlinked cracks that form blocks resembling alligator skin are known as alligator cracks. Alligator cracking occurs for a variety of reasons:
Root Damage: Root damage regularly occurs in aged parking lots. This is a serious problem that requires the attention of asphalt maintenance experts. When parking lots are built, trees and plants are often planted. As time progresses, these trees grow and their roots expand. Some root systems grow down into the asphalt pavement. The asphalt subsequently rises and breaks. The result is a maintenance issue and even a safety hazard. Such an area must be cut so the roots can be removed and the root damage replaced. In some instances, lime rock base must be added and compacted prior to placing at least an inch of specialized asphalt.

I like how you said that the best form of preventative maintenance is to use lots of pavement sealer. My uncle's driveway needs to be replaced sometime soon. I will have to mention this to him.

Eliminating all the dirt from your catch basin and your pipes is such a good idea! I have a driveway that is made of asphalt and I have a lot of water that pools on it. I'll go check my drains and make sure they're not clogged.

I like that you said that when the asphalt becomes too thin, it means that you need a new asphalt overlay. My dad told me that his driveway was developing cracks and he said he wanted to fix it before the winter. Thank you for helping me learn more about how to know if you need a new asphalt layer.

It's good to know that pavement sealer can prevent asphalt from breaking down over time if it's applied every couple of years. My parking lot is getting pretty old and will need to be replaced next year. Maybe I should look into getting it sealed afterward so it can stay in top condition for a long time to come.

I like that you mention the importance of maintaining your parking lots draining system since water can cause pavement distress. My husband mentioned that the parking lot around his office is in rough shape. I think they should look into hiring a commercial paving company to either fix it or have it replaced.

It got me when you mentioned that asphalt must be repaved completely if the cracks are more than half-inch. That is the very reason why we need an asphalt repair. I noticed that the cracks are wider than a half-inch, so it must be fixed immediately.
