Different materials can be used to construct pavements including bricks, stone, stamped concretes, and asphalt. However, the asphaltic material offers far more durable and cost effective option. Although other materials may be durable, they are costly. However, with asphalt paving Phoenix AZ contractors, installing pavements may be cost effective for you.
The asphaltic paved surfaces have good visual appearance which gives the premises that eye grabbing attention. A new asphaltic pavement is most flexible since it still has much of the lighter hydrocarbons oils on the surface. It has a good elasticity which makes it perform better. Many of the problems with pavements begin when the asphalt materials dries out and hardens.
The thousands of dollars you spend need to create value from the finished structure. This is why you have to deal with contractors who are trusted and use the best practices. Asphaltic driveways can survive for many years if they are installed properly and maintained in good condition. One thing that poses potential damages is cracks.
However, no matter how you try to take care of asphaltic pavements, they will eventually develop cracks. This is something you have to be prepared to deal with. The durability and strength of your pavements is determined by the initial construction practices and materials used. The ground where driveways and parking pavements are to be constructed should be prepared.
In the installation of aggregate layer, about five to eight inches of crushed stones and aggregates are compacted using rollers before the asphaltic finish is applied. The stability of pavements is determined by the strength of sub base. With a strong base and sub base, you can have a very durable pavement. However, if you have a blacktop that sits on a weak sub base, you may soon experience problems like depressions, potholes, and cracks.
Your pavements have to be remedied with use of a sealcoat. However, a sealcoat only works if there are only fine hairline cracks. At times, the fading of pavement may be accompanied by visible cracks. With the highly visible cracks, other repair methods can be applied such as overlays.
The oxidation process causes pavements to become brittle and hardened. They cannot expand or contract uniformly in times of weather changes. Asphaltic materials last for many years because they can expand and contract. When it is hot, the material expands and when it cools, the pavements contracts. The same happens when the vehicle loads pass over pavements. The pavement materials can move and get back to their shape thus reducing the chances of cracking.
Sealcoats help restore the black color, the elasticity and flexibility of blacktop, as well as the seal of small tiny hairline cracking. Sealcoats are not restoration procedures but they can be applied to seal the fine hairline cracks since they are not elaborate and profound. The sealcoating is applied after the newly constructed pavement has cured. It takes about six months to one year before the blacktop cures properly. If you apply sealcoat before the pavements cures, it will not bind properly.
