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.
Sometimes in parking lots you’ll notice polls sticking out of the ground. These are bollards. Bollards are used to control traffic, protect areas and serve as decorative pieces. We will go through out bollards came to be and dive a bit deeper into their purposes and how they keep your parking lot safe.
Bollards were first used by ships for anchoring to the dock. They needed a way to keep the ships from drifting off to sea and so they took old cannons and stuck them into the dock, with the barrel facing down and the wider bottom at the top. They would then tie the ships to the dock to help anchor them. They would call these structures bollards.
Today bollards have increased their purposes and are used in parking lots to create a better functioning parking lot. Bollards are now often made from steel and concrete and come in different styles in order to meet the decorative look of your parking lot. There are several main purposes to bollards which we go into further below:
Bollards are used for traffic control. Bollards are tall intrusive points that stick up from the ground. They are visual aids that help drivers know driving restrictions and help to guide the drivers as they drive away from areas they are not supposed to go into. Bollards are normally bright in color in order to stick out and help clearly direct the drivers. They help to limit movement of cars. The placement of the bollards could also help with slowing traffic down. Bollards that are placed close together and make the driving space narrow helps to slow cars down. Drivers are more careful when they are driving close to bollards.
Bollards are used for protection. Bollards help to protect pedestrian ways, sidewalks and storefronts from cars. Bollards are strong and sturdy so cars cannot by pass them. If a car loses control or rams into a pedestrian filled place, it will be stopped by the bollards. This protects against car attacks and keeps pedestrians safe.
Bollards are used for decorative pieces. Bollards come in all different colors and styles making allowing you to use them for decorative purposes. They are helpful for designing purposes and crating intentional spaces that look good.

Potholes are very annoying at best and dangerous at worst. They are not fun to maneuver around and can cause serious damage to your car if you are going fast and don’t see it. But how do potholes get there? Why do they happen?
Potholes are caused when water sinks into the asphalt and reaches the base. In freezing conditions, the water inside the pavement begins to expand as it turns into ice. Ice takes up more space than water and begins to create cracks in the asphalt. As the water freezes and melts over and over again it causes the asphalt to become a weaker structure.
As the asphalt structure becomes weaker, it has a harder time handling the weight of the cars. Pressure given at the wrong angle can cause the pavement to crush in, causing the pothole.
Sealcoating and proper drainage help to keep water out of the pavement. If asphalt pavement is not maintained then it leaves itself vulnerable to the outside elements. In order for asphalt to stay in good condition it needs to be sealcoated every 3-5 years depending on the amount of use that the road gets. If it doesn’t receive the maintenance and protection it causes the pavement to become distressed.
Sealcoating is not a solution once the road has cracked. Once the protective sealcoat layer is thinned or gone then water is able to easily seep into the asphalt pavement. At this point it is pointless to put sealcoating on the top because the water is already in the asphalt and will continue to cause problems even with a fresh layer of sealcoating. In this case you’ll need to get the pothole repaired and then consider getting sealcoating done.

Speed humps and speed bumps are techniques used to control speed on the roads. They are used to slow cars down in order to promote safety in an area where cars tend to speed. There are regulations on where and how speed bumps and speed humps can be used. This is to protect the driver and those around them.
First, what is the difference between a speed hump and a speed bump?
Speed bumps are abrupt raises in the asphalt pavement that are between 3-6 inches high and 3-6 inches wide. Speed bumps tend to slow cars down to 5 mph.
Speed humps are gradual raises that peak at between 3-5 inches high. They are typically 12-14 inches wide. Speed humps tend to slow cars down to 15 mph.
Secondly, how are they used?
Speed bumps are limited in where they can be placed. Speed bumps can cause a lot more damage than a speed hump if a car is going too fast as a result of their abruptness. If a car is going too fast over the speed pump it can cause the driver to lose control of the car. As a result, speed bumps are mostly used in parking lots or private drives since people are not driving the same speed they would on a street. It helps people to slow down and be more cognizant of pedestrians in the parking lot.
Speed humps are a little less invasive and are used in neighborhoods and small streets in order to slow cars down. They have more of a gradual rise which helps put less distress on the car when riding over it. Cars are less likely to lose control over a speed hump. Down longer streets there tends to be a network of speed humps to help regulate the street.
In both these cases there are restrictions of where speed bumps and humps can be used to control speed. Engineers have to be called in when considering to put a speed hump or bump on a side street to make sure it will not cause any problems. In addition, the emergency routes need to be considered as speed bumps and humps tend to hinder emergency groups from being able to respond quickly. In some cases, cities will not allow there to be speed humps or bumps put out if it will hinder emergency response. In colder climates where snow is an issue, the city also looks at how speed bumps and humps will affect the clearing of the streets.
We help to install speed humps and speed bumps. If you are looking for assistance in getting speed humps or pumps for your parking lot, neighborhood or road give us a call!
If you own a shopping center or retail location there are many things you have to look out for to make sure that you are up to code. One of the things you have to think about is your parking lot and ensuring that you have proper signage for your parking lot.
One of the most regulated and necessary signs you need are parking spots and signs for accessible parking. When a parking lot re-stripes it is required by ADA to make sure that it is up to status. Your handicap parking spots needs to be in the most accessible and short distance spot to the entrance of the door or to the sidewalk. It needs to have a 96’’ access aisle to accommodate for wheel chairs. The sign needs to be at least 60 inches from the ground in order to be clearly seen by drivers.
One of the signs you want to heavily consider is towing signs. If you are serious about enforcing towing you need to make sure that you have provided the proper signage. Each city is different so be sure to check the laws regarding towing. Most places you have to have the towing sign at each entrance of the parking lot. On the sign there must be the contact information for the towing company and also a statement stating that the towing will be at the cost of the driver.
Depending on building code you might have to have a fire lane. If you do have a fire lane you want to make sure that it is stripped correctly and you have the right signage for the lane.
There are several other signs that you might find helpful for your parking lot including:
If you are looking to get your parking lot re-striped, get bollards put in and get your signage right consider reaching out to us. We are your one stop-shop for parking lot paving, maintenance and repair. Give us a call today!
