What is the Typical Life Cycle of an Asphalt Parking Lot?

No matter how sturdily a structure is laid, it will eventually reach a time when it will require maintenance or replacement. The period it takes before reaching such an instant defines a structure’s lifecycle. Asphalt parking is one such structure, and if you own one, then you need to keep updated on essential aspects that define its lifecycle.

Various factors affect the lifecycle of an Asphalt parking lot. Environmental conditions, design and construction elements, water drainage means, frequency of maintenance, and significant of all, traffic load, are some of the critical aspects to the lifecycle of an Asphalt parking lot.

In this article, we shall focus specifically on the lifecycle of an asphalt parking lot as well as factors signifying a need for maintenance or replacement.

Asphalt Parking Lot’s Life Cycle

In overall, a standard asphalt parking lot can last for up to 25 years. However, this period can reduce or increase depending on asphalt maintenance regularity. But what happens during this lasting period?

Well, let’s have a look.

0 to 5 years: For the first five years since construction, your asphalt parking is still strong and probably shows little or no signs of damage. If anything, the surface might have insignificantly deformed while color discoloration might be visible, especially if it is extensively exposed to sunlight.

5 to 7 years: During this period, your parking lot starts experiencing minor cracks, thereby necessitating for maintenance services. Practices such as crack-sealing and seal-coating are necessary at this stage.

7 to 15 years: With proper maintenance practices during the previous phase, your parking might not undergo significant damages for the next 15 years. However, you should continually check for damages while ensuring necessary maintenance practices for prolonged endurance.

15 to 25 years: After 15 years of use, you should expect your Asphalt parking lot to have started developing visible cracks as well as considerable deformation. If such damages are significant, you might need to resurface your parking lot.

Over 25 years: beyond 25 years signifies the end of the parking’s life cycle. During this stage, it has undergone extensive damages and probably multiple repairs, which means it might no longer withhold the weight of your vehicle. If more repairs seem to be of no help, then you can reconstruct the entire structure.

Maintenance Practices Timing

Maintenance involves various activities including crack-sealing, seal-coating, and resurfacing, all which should be timely carried out. But how do you determine the best time for every maintenance practice?

Crack Sealing

Filling of small cracks in your parking lot should be done using a liquid concrete filler. Cracks to seal should be small, not exceeding half an inch in terms of width. You should schedule a crack sealing exercise every year to extend the lifecycle of your asphalt parking.

Seal coating

As one of the concrete maintenance activities, seal coating is meant to reduce concrete exposure from the effects of sunlight, spillages, water, and air oxidizers. Seal coating should be best carried out immediately after the crack sealing process or any other time beyond six months when damages start revealing.

Resurfacing

Extensive damages might eventually necessitate for resurfacing process. It involves adding a new asphalt layer on top of the existing one, a process also referred to as overlaying. This process should only happen after a decade of parking construction. You should also initiate it during favorable weather conditions, preferably during warm seasons.

Final Thoughts

Since timely maintenance is essential for your asphalt parking lot, you need to be observant on the emergence of an issue. If conditions such as cracks are unattended to, they may continually weaken the surface leading to a reduced timeline. Moreover, you should act on any issue you identify as soon as possible.

Common Concrete Issues

Concrete is a common material used due to its durability and versatility. Under the right conditions, it is a sustainable material. But, there are numerous common concrete problems, which can prevent concrete from attaining its longevity. Recognizing these problems and understanding the solutions can improve the overall performance of concrete. The common concrete problems include dusting, blistering, plastic shrinkage cracking, discoloration, and scaling.

Dusting

Dusting on concrete occurs when a hardened concrete surface appears as a powdery material. Laitance, which is a layer of cement, water, and fine aggregates is the primary reason why dusting occurs on concrete. The laitance layer is weak, porous, and thin. As a result, the laitance makes the hardened concrete surface vulnerable and weak.

Other reasons why dusting appears include improper cure of the concrete surface, exposing the concrete to carbon dioxide while it is in a plastic state, and conducting finish operation on the concrete surface while it still has bleed water—this is water that separates itself from the concrete.

To avoid these problems, proper concrete curing procedures should always be followed; equipment that produces carbon dioxide should always be vented while the surface is in the plastic state, and the finishing operation should always be conducted on the concrete surface after bleed water has been removed.

Blistering

Blistering appears on a hardened or fresh concrete surface as bumps. These blisters occur when bleeding water or entrapped air rises to the sealed concrete surface. Blistering of concrete surfaces is problematic, as it causes the concrete to break easily under stresses like traffic. Other reasons why blistering occurs include excessive or inadequate use of vibration during concrete compaction, setting concrete surfaces over the vapor barrier, and sealing the concrete surface early.

To prevent blistering from occurring, appropriate concrete compaction procedures have to be followed, if possible, concrete should not be placed over vapor barriers, and trowel blades must be kept flat at all times to avoid sealing the concrete surface early.

Plastic Shrinkage Cracking

Plastic shrinkage cracking occurs when a crack appears on fresh, hardened concrete surfaces. Like the name suggests, these cracks develop while the surface is still in the plastic state. These cracks occur when the concrete surface experiences a rapid loss of water before it sets. Although plastic shrinkage cracking is an aesthetics issue and not a structural issue, these cracks end up allowing chemicals to penetrate the surface, and this can result in structural problems later on.

The loss of water on concrete surfaces can occur due to several reasons like low relative humidity, high winds, and high concrete temperature or ambient air. To avoid these conditions, ensure you use fog spraying equipment, windscreens and windbreaks should be installed, and always avoid placing concrete at midday.

Discoloration

Discoloration of concrete can occur due to various reasons like material exposure, weather conditions, and even the curing time. Although concrete discoloration may look aesthetically unpleasing, there are numerous ways you can repair these issues. The first method is using a concrete cleaner. These will help give the concrete a better and natural look. If that does not work, you consider using a concrete stain.

Scaling

Scaling on concrete surfaces occurs when the surfaces start to chip or flake away. This is usually because of freeze-thaw, water seepage, poor concrete finishing, or weak concrete surfaces. To repair scaling issues, use trowel-grade light coat, as it helps fill the scaled area. Also, ensure that you seal your concrete at all times, as this helps to reduce scaling significantly.

The Top Reasons You Should Be Sealing & Finishing Your Concrete

When properly installed and maintained, concrete has a lot to offer to business owners. This manmade substance is affordable, durable, attractive, and easy to keep clean. Having your concrete finished and sealed is key to getting the best results.

So what are finishing and sealing? Finishing is a process that smooths down the surface of the concrete. It’s typically done when the material has had time to partially dry but is still soft and workable. Sealing, meanwhile, is the application of various substances like acrylics, epoxies, and silicates. When applied to clean and dry concrete, they form a protective barrier. If these two jobs are skipped or rushed, you may find yourself with an expensive headache on your hands.

Here are the top five reasons why you need to have your concrete finished and sealed to keep it looking and functioning great:

1: Finished Concrete is Safer

The process of finishing concrete creates a smooth and level surface. It eliminates most of the micro-ridges and hollows that roughly poured concrete can have. This means that the surface doesn’t have hidden tripping hazards which your employees or customers could stumble over. Liquids will also glide away instead of pooling and creating slick spots. Finally, a smooth surface will not damage tires or objects placed on it.

2: Finished Concrete is Stronger

This advantage is due to several effects. Properly finished concrete has shed its excess water while maintaining the mix’s integrity. When the water evaporates, a highly durable form of concrete is left behind.

A flat or gently banked surface also does not collect rainwater, spilled chemicals, and other such substances. These liquids can eat into the concrete, creating pits that may turn into potholes over time. If the spills happen in freezing winter temperatures, the concrete will become damaged even faster. Although heavily damaged concrete can be repaired or resurfaced, these are major expenses that a savvy business owner can avoid.

3: Sealed Concrete is Protected From the Climate

Concrete companies urge you to seal your new concrete floors, parking lots, and sidewalks for good reason. Rain, ice, and snow are more likely to get into tiny cracks and pits in unsealed concrete. Sealing creates a water-resistant barrier that adds to the longevity of this material.

Certain kinds of sealers will also chemically penetrate the concrete. This creates a denser and stronger material. Your concrete contractor can advise you on the best products for your business’s needs.

4: Sealed Concrete is Easier to Keep Clean

You don’t want to work in an unsightly environment or have your customers see mystery stains on the concrete. Sealant can protect this surface from discoloration due to road salts, motor oil, spilled chemicals, etc. These dry and sealed surfaces also resist hard-to-remove mildew and staining mold growth.

5: Sealed Concrete is Stylish

Different concrete sealers can create different effects. One type may have an attractive high shine gloss reminiscent of polished marble. Another might create a matte finish that reduces glare from the sun. This can be a great feature in sunny working areas.

You can also order tinted concrete sealers. These come in a wide variety of color options, from neutrals to brighter shades. However, tinted sealers aren’t just for looks. Ask your concrete company to lay down strategic stripes or boxes of contrasting color and you can mark out walking paths, dangerous loading zones, and more.

How to find the best concrete maintenance contractors?

Hiring the best concrete maintenance contractor is not always simple. You want a contractor who is honest, dependable, and qualified for the job at hand. Make sure you are asking the right questions when you interview a company. If you don’t, you could be paying more than expected, and the job may take longer than you want.

Here are 5 ways to choose the right concrete maintenance contractor for the job.

  • Ask to see their portfolio. When you are doing your research, make sure to check the contractor’s portfolio. The right contractor will be able to show you a gallery of photos. You will have the chance to see their most recent work and get a better idea of what they can offer you. You will be able to check their services and get an idea of what to expect from a final project. Their portfolio will allow you to visualize what they can do for you and your home, and maybe even give you some new ideas.
  • Look for a contractor with experience. Generally, you should look for a contractor with at least five years of professional experience. This will demonstrate that they are reliable and will provide you with quality work. Additionally, experienced contractors will be able to offer you suggestions to help you get the results you are looking for. They will explain how one concrete option is better for your space than another.
  • Check their reputation. Take a look at the contractor’s reviews. You should be able to find them on Google, Yelp, Angie’s List, HomeAdvisor, or Facebook. Do the reviews say the company is reputable? Are they easy to work with, friendly? Look at the bad reviews and see if the company responded and tried to rectify the complaint or offered a solution. You may also want to ask friends and family if they know of a contractor, or if they know anything about the company you are considering.
  • What does their insurance cover? It’s very important to know up front what, exactly, a contractor’s insurance covers. If there is any type of mishap on the job, you want to make sure you won’t be liable for it. Find out how the contractor’s insurance protects you and your property from things like on-the-job accidents and damages. Typically, a reputable contractor will have general liability coverage and worker’s competition policies. You can also choose to contact the contractor’s insurance company directly to verify they have coverage and what it covers.
  • Finally, make sure to get an estimate. When you speak to each contractor, request an estimate for the project. Make sure they have included everything; the cost of the base materials, the thickness of the concrete, reinforcement, coloring, sealer, and the down payment. Then collect these estimates to compare with other contractors. Look at what each contractor offers. What will you be paying for with each one?

Make sure you talk to several contractors before you make your choice, and make sure to read your contract carefully before you sign. When you make your final decision, look at each of these factors and weigh them. One contractor may charge a little more but will offer better quality and better customer service. Look at what you will be getting for the price and make sure the contractor offers everything you need. And finally, don’t pay your balance upfront. A reputable company won’t ask you to.

Asphalt Pavement vs Concrete Pavement

Although the most obvious difference between asphalt pavement and concrete pavement is the appearance, there are many more differences that you may not notice at first sight. When deciding between the two surfaces, appearance is only one of the many factors to consider; continue reading to learn about the five main differences between asphalt and concrete: cost, lifespan, upkeep, sensitivity to temperature, and ease of repair.

Cost

When deciding between asphalt and concrete driveways, price is often the first consideration. Asphalt is typically cheaper, running $2-$5 per square foot on average. Concrete prices begin around $3-$9 per square foot. Many people who choose concrete driveways opt for customized designs, which can drive the price even higher.

Lifespan

While concrete may cost more initially, it has an average lifespan of about 30, and even up to 40 years, compared to an average lifespan of about 20 years for asphalt. This makes costs more comparable when thinking about the long term. This is something to consider when deciding between the two. If you will be in your home for 30-40 years, concrete may actually be more cost effective in the long run. Regardless of the pavement type, both require strategies for upkeep.

Upkeep

In order to keep asphalt pavement functioning to its highest potential, it needs to be re-sealed every few years. For asphalt pavement, sealing is strictly for function, and not for appearance, as the dark color of asphalt naturally hides stains and spills.

Concrete does not require as much upkeep, but it is more likely to stain or fade over time, so in order to maintain the appearance of concrete pavement, it can also be sealed.

Sensitivity to Temperature

If you’ve ever flown from north to south or vice versa, you’ve probably noticed that the majority of the driveways in the north are asphalt, while the majority of driveways in the south are concrete. This is because of how well each material withstands and reacts to temperature.

In extreme heat, asphalt can become gooey and even start to melt, and when it gets cold, it becomes much harder and more brittle. When asphalt continually goes through these temperature fluctuations, it is much more likely to crack.

Concrete, on the other hand, has a tendency to crack and buckle in extreme cold. Concrete also tends to be more popular in warmer climates because it doesn’t retain heat like asphalt does.

Ease of Repair

Even when you do everything you can to properly maintain a pavement surface, damages may still happen. When asphalt cracks or develops holes, it can be filled and sealed relatively easily. Because of the dark color, repairs are not very noticeable.

When repairing cracks in concrete, the repairs can be extremely obvious. Often, when there is a crack in concrete asphalt, the decision is made to replace the entire surface, rather than trying to repair and match the existing surface.

Conclusion

If you’re trying to decide between asphalt and concrete pavement, be sure to thoroughly research and think about your options. Your budget and the climate in which you live might be two of the biggest factors to take into consideration.
