The majority of residential and also commercial driveways are finished with concrete or asphalt.
Both are reasonable in terms of price but asphalt has more advantages in the long run.
The way it is made says it all: concrete is made of aggregate (sand, crushed rocks…) mixed with cement and water. Asphalt is made of aggregate too but its binder is bitumen. Both are durable and hard but asphalt accommodates imperfections a lot better.
Faster Installation and Usability
Asphalt pavement can be installed in as little as a one or two days and you will be able to use it after waiting for only another couple days. Installation duration depends on the size of your driveway obviously. Once the asphalt reaches outside air temperature, it can withstand traffic.
If you compare this to a concrete pavement that takes twice longer to be installed and set, there is really no comparison possible. Asphalt wins in this case.
Concrete is a lot more prone to cracking and breaking compared to asphalt. Asphalt has a lot more flexibility and is less prone to cracking over time. Poor installation of your concrete can result in what is called “spalling”. Your driveway will remain in better condition for a longer time if you use asphalt.
Lower Maintenance Costs
If your asphalt driveway starts showing some signs of aging such as linear cracking, you can easily purchase a crack sealant on your own. Many home improvement shops sell it freely and you can apply all by yourself without even calling a professional. You can do it by yourself in one afternoon. All this will save you money in the end.
We strongly recommend that you perform preventive maintenance tasks on a regular basis if you want to increase your driveway lifespan. Sealcoating, crack filling, sweeping…all these operations are generally enough to maintain your asphalt driveway in good condition. In contrast, it is a lot harder to maintain concrete driveways since they can’t be heated and repaired as easily as asphalt.
Asphalt’s black color is an added benefit
Black retains sun and heat better than concrete. It means that during winter snow will melt faster. It is an added feature that increases the safety of your residence and your commercial premises.
And don’t forget that asphalt is 100% recyclable. Whether it is for a new construction or repairs, asphalt is the wisest choice you can make for the long term. Cement paving is a lot less convenient in comparison.
In conclusion, asphalt paving will provide you with better structural integrity and a more pleasant driving surface, even if you use heavy vehicles.

Understanding the makeup of a product helps you to better understand how and why it deteriorates. This gives you a better understanding of how to prolong the life of the product.
Asphalt is comprised of various rock aggregates and a binder that holds them together.
You may wonder, what are aggregates? Aggregates refer to a mixture of gravel, stone and sand. It is a rock mixture comprised of various size and shaped materials. The size, shape and makeup of the aggregate can be changed to best fit with the climate of where it is being laid.
The binder that is used in asphalt paving is made from crude oil. When crude oil is processed, some of it becomes gas and what is left over is used to make the binder for asphalt. The binder does exactly what it name connotes, it binds or sticks the aggregates together.
The mixture of aggregates and the binder, also known as bitumen, makes asphalt a more flexible product than concrete. Concrete also uses aggregates comprised of a mixture of gravel, stone and sand, but its binder is cement. Cement is a strong substance that once is dried, does not change. The bitumen, while a strong substance, is more flexible and can handle larger changes in temperature.
Asphalt must be laid at temperatures of 270-350 degrees, which allows bitumen to be in a more flexible state to be laid and then compacted. It is rolled over with a roller to compact the asphalt. It then takes 24-48 hours to cure, depending on the outside temperatures. After that asphalt is ready to be driven on, but it doesn’t fully cure for a couple months, which is why you want to wait to sealcoat asphalt until it is fully cured.
As soon as asphalt is laid it begins going through the process of oxidation. Oxidation happens when oxygen from the air and water come into contact with the chemical compounds in bitumen, causing it to dry out. This is necessary, at first, to help cure and harden the asphalt. The oil within asphalt tends to make it a more flexible substance than concrete and helps with being able to manage traffic loads and varying temperatures. Over time though, the oxidation process will weaken the structure of the asphalt pavement, making it more brittle and less forgiving to colder temperatures that can cause freezing and thawing, causing it to be more susceptible to cracks and potholes. This is why it is important to sealcoat your asphalt in order to delay the process of oxidation. Over time, the asphalt will turn from black to light gray as the process of oxidation runs its course.
Now that you know that oxidation weakens the binder of the asphalt, as the oxygen in water and air change the chemical structure, how do you help protect against it? You can make sure that your pavement is constructed in a way that allows for irrigation so that water does not cause damage to your pavement. In addition, you can sealcoat it regularly to help protect the pavement.
If you are a heavily busy business area then your paving takes a beating. As customers come in and out of your parking lot, your parking lot gets put to good use. Having a heavily used parking lot is a good problem to have, even if it means you have to take even more care of your parking lot. The goal at the end of the day is to have more customers, but with more customers comes more upkeep.
There are 3 things that you can do to help protect your asphalt pavement from the many patrons visiting your location every day. Here we will go over somethings that you can do to help your pavement last longer.
Trying to be compliant to building codes can be hard. And there is some confusion between being ADA compliant and being code compliant. Just because you are ADA compliant doesn’t mean that you are being code compliant. You may wonder, why? ADA compliance comes down from the federal government. This means that everyone needs to follow these codes regardless of what city or state you life in. However, individual states and city may make their own codes that are more strict then the ADA compliance codes. The best way to make sure that you are compliant is or you to check with your city’s code compliance offices to ensure you are making the best decisions about your business’s building.
When you are looking at your parking lot there are somethings you want to ensure to make sure that you are ADA compliant. Each parking lot needs to have a certain amount of accessible parking spots. Each parking lot needs at least one van accessible spot and for every 6 accessible spots there needs to be at least 1 van accessible spot. Below you can see the chart of how many accessible spots are needed based on the number of parking spots provided.
CAR VS VAN REQUIREMENTS
Car accessible spots require the following:

Don’t forget to check out to see if there is any tax credit available for you to make these changes. Small business may be eligible for up to $5,000 in tax credits for making changes to the parking lot. Small business are defined by the IRS as business that have less than 30 full-time employees and had a gross product of $1,000,000. Other business may also be able to receive up to $15000 in tax credit for the purpose of removing barriers on property in order to provide better accessibility.

There are several factors that will affect the quality of your pavement and the length of time that it will last. Being proactive about mitigating some of these issues will allow your pavement to last longer.
One of the major factors affecting the life of your pavement is correctly assessing the amount of traffic that will be driving on your pavement. If you are a retail location that will be undergoing reconstruction and might have heavy machinery on your pavement it is important to take note of that when getting your pavement done. Pavement should always be laid for the heaviest traffic load it will need to carry. Pavement is made from a flexible material, but if the traffic load is too heavy it will cause cracking. Talk with your paving contractor about the use of your parking lot and ensure that it is able to bare the correct traffic load.
The second factor affecting the life of your pavement is water. Water can have devastating effects on your pavement if your pavement is not protected correctly. Water can get in and cause cracks and if these cracks are not taken care of then they will grow into bigger and multiple cracks. The way to prevent water from negatively affecting your pavement is by creating proper drainage for your asphalt pavement. Your paving contractor should ensure to create proper drainage for the pavement project so that no water pools on the pavement. Also making sure that your pavement is properly sealed will help protect against water seeping into the pavement.
Another factor that will affect the life of your pavement is the subgrade and subbase. If the underlying layer of your pavement is not built up correctly then the weight of the traffic on your pavement will not be evenly distributed and will cause too much weight and pressure on the asphalt, causing cracking to occur. There are many different ways that an improperly constructed subbase can cause pavement to fail. To guard against this make sure to hire a trusted contractor who will make sure that you have a strong, solid subbase.
The quality of your pavement and its life will be effected by the amount and type of maintenance that you perform. Asphalt needs maintenance to ensure that it is protected from external elements. To increase and protect the quality of your pavement, be sure to get cracks filled promptly and to deal with the root issue of the cracks to ensure that they do not come back again.
There are several types of deformations that can occur on the surface of the pavement due to weakness in one of the layers. The main four types of deformations that you may see on the roads are: Rutting, Corrugations, Shoving, Depressions and Swells.
Rutting occurs in heavy traffic areas. The rutting follows the tire lines of cars. It is caused by displacement of asphalt material as the cars drive over them. Ruts begin to appear over weakened areas. These areas can hold water. Rutting can occur in the subgrade, subbase or on the top layer, depending on where the weakness is.
Corrugations occur in areas where heavy acceleration or deceleration happens. It is important to get asphalt with the correct mixture suitable for the paving job. Corrugations occurs when there is too much cement or too much small aggregates. It resembles ripples and is often known as washboarding.
Shoving is the movement of the pavement similar to corrugations where there is a bulging of the pavements. These bulging often occurs in areas where there are heavy amounts of acceleration or deceleration as they cause the moving of the asphalt aggregates.
Depressions occur when there is a movement in the base layer, underneath the asphalt pavement. When shifts occur the pavement also becomes depressed. Eventually these depressions will result in potholes that become dangerous for motorists.
These are the main types of deformations that you might see on the road. Most of these deformations happen in heavy traffic areas where there are a lot of cars that cause these deformations. Constructing the asphalt pavement in the correct manner with the right mixture of aggregates at the right temperature will help to mitigate some of these effects. If you are experiencing some of these issues on your road be sure to reach out to an experienced asphalt paving contractor that can correctly assess and determine the causes of these deformation and provide the right solution to repair your road.
There are several types of cracks that can occur in your asphalt pavement. These cracks occur to a wide variety of reasons. Knowing why these cracks occur helps to best know how to mediate the effects of the cracks and repair the problem area.
Fatigue Cracking is also known as alligator cracking. The main reason for fatigue cracking is due to heavy traffic load on the roads. Roads should be built for the largest traffic load that it will have to carry. Excessive traffic load causes the road to crack, as it is not able to carry the weight of the load.
Longitude Cracking/ Transverse Cracking
Longitude cracking and transverse cracking are both long lines that appear in the road. Longitude cracking occurs in the direction of the traffic and lines up with the center of the road, while transverse cracking is perpendicular to the center of the road. These types of cracking are usually due to drainage and frost problems. Once water gets into the asphalt pavement it will begin to freeze and thaw and this process of freezing and thawing will create cracks. If these cracks are not taken care of then they will cause further parallel cracks. This process is also known as deterioration.
Reflective cracking occurs in the case where there is an overlay on the asphalt. When cracks are not properly fixed on the underlying pavement then the cracks will eventually migrate to the top layer. This is why it is called reflective cracking, as it is reflected in the top layer. This is why it is important to get cracks filled and taken care of prior to having an overlay put on your current asphalt.
All these types of cracking can lead to potholes if not taken care of early on. It is best to take care of your asphalt pavement when you first see cracks to prevent further cracking from happening. Call a paving contractor who can correctly assess the cause of the cracks and get the root problem fixed.
When you start on as big of a project as paving you want to make sure that it is going to last. There are three major things that cause asphalt pavements to fail.
The first reason is improper thickness of asphalt. Sometimes cheap asphalt contractors who are trying to bid for your business will quote you a lower cost, but often what is happening is that they are budgeting for less asphalt. This could be dangerous for you because less asphalt means that the pavement is not as strong as it needs to be to bare the load of the cars riding on it. Different paving projects will need differing amounts of asphalt laid, depending on the weight it is expected to carry. For example, a parking lot for a busy retail location is going to need a lot more than a driveway that only has 2 cars that use it. You want to make sure you are using a trustworthy paving contractor who will ensure that the asphalt is thick enough to handle the weight it is expected to carry.
The second reason asphalt pavement fails is due to shifts in the subgrade. The subgrade is the native soil that is under the asphalt. A good contractor will make sure that the area underneath the asphalt has a good subgrade and a good subbase. Occasionally there will be shifts in the subgrade due to moisture, heavier than expected traffic load, roots growing deeper moving the soil around and other circumstances. A good subcontractor knows how to mitigate that from happening and ensure that you have a strong enough subgrade and subbase to carry the weight necessary.
The last reason asphalt pavements tend to fail is due to lack of maintenance. It is important to maintain your asphalt pavement to protect it from external elements that might try to damage the asphalt pavement. If you notice any cracks starting to appear, it is important to get them sealed right away. The longer that cracks remain open, the more water can get into the cracks which will cause long term damage to the asphalt pavement.
A good paving contractor will help to mitigate some of these potential issues. If you would like a consultation with our expert contractor then give us a call today!
All pavement will eventually deteriorate and not be as strong as it once was. If you do proper maintenance then this will happen later rather than sooner, but if you don’t then it will happen sooner than later. Throughout its lifetime, the asphalt binder which holds all the aggregates together begins to weaken. As oxygen leaves the binder it becomes dryer and less flexible and less able to hold the aggregates together. Maintenance in the form of sealcoating allows the binder to be protected and not give out as quickly. If you are interested in learning more about sealcoating visit our page on sealcoating.
But if you are getting to the point where your asphalt needs to have a new layer so that it can be returned to the pristine blacktop you loved at the beginning, you’ll need to get a consultation of how to best – and most economically – restore your asphalt pavement. One of the options you may consider is an overlay. One of the biggest issues when considering doing an overlay is the issue of cracks in the previous pavement. Paving over a cracked asphalt pavement will cause you more trouble sooner than later. The cracks from the previous pavement will be an uneven surface for the new asphalt overlay causing reflective cracking, which is cracking that comes up to the new layer of paving from the old layer. Then your back to where you started.
Permaflex solves this solution by wedging into the cracks and sealing them up. Permaflex helps to create a good foundation for a new layer of asphalt. The cracks are filled in so they will not cause damage to the new layer of asphalt and the Permaflex allows the old asphalt paving to be a solid subbase for the new overly.
Prior to using Permaflex it is important to make sure that the underlying asphalt is solid. Repairs may need to be done in order to make sure that further cracks will not happen due to uneven grounding that may have shifted after asphalt was laid or that any potholes are fixed up.

Your concrete driveway goes through a lot. Luckily, they are durable, but they are susceptible to oil stains. If your car starts leaking then your driveway will get covered in oil. And with concrete driveways the oil stain stands out – there is no way of covering it. Oil stains become eye soars and it can be frustrating that your once beautiful driveway now has stains. Unfortunately, you can’t just use a pressure washer to get out those stains. However, there is one house hold item that you can use to get your oil stains out of your concrete driveway: kitty litter.
Now your, saying “what?! kitty litter?” Yes, kitty litter. The problem with oil is that it sinks into the ground. No amount of scrubbing and high pressure water will get it out. You need something that is absorbent that will soak up the oil from the ground. Kitty litter is super absorbent (or at least you hope it is!), so it’s a good household item that you might have that will work to get the stain out.
The best kind of kitty litter to use is actually the cheapest kind you can find. The cheap kitty litter tends to be more finely ground and more absorbent, making it better for this process. Once you have the kitty litter follow these steps:
This is one cheap method to get rid of the oil stain on your concrete floor. You can use other products. The key is to get something that is absorbent that will work to get the oil out of ground. It’s not like dirt that you can just scrub and sweep away. Oil needs to have something that will pull it out of the material.
