Install Parking Lots With The Services Of Asphalt Paving Phoenix Contractors

By Marcie Raymond


Asphalt is one among the many types of materials used to pave surfaces including concrete slabs, natural stones, and bricks. It has a good shelf life and can last for over 15 years when installed properly and maintained in the right conditions. If you plan to pave surfaces, you can contact asphalt paving Phoenix contractors to design the pavements.

Asphaltic material is a cheaper option when you install pavements. Its initial cost of installation is not high when compared to other paving materials like natural stone or bricks. Once you have installed asphaltic pavements with the right sub base compaction and blacktop thickness, then you have a structure that can last for long.

Nonetheless, you need to constantly maintain the surfaces and prevent them from suffering premature damages. Cracks are things you will deal with often with blacktop pavements. These cracks are caused by things like drying of asphaltic material, the heat from sunlight, and pressure exerted by vehicles. Depending on the nature of cracking, the contractor will use the right procedure to repair them.

With time, small crack appear forming hairline cracking. The surface also unravels and leaves small stones on top of pavement. Sealcoating is applied to restore the elasticity of pavements and prevent damage from sun, water, and petroleum products. Sunlight produces ultraviolet rays, which increase the normal oxidation process of asphaltic material.

To maintain it in good shape, you need to apply a sealer product to rejuvenate it and make it more elastic. The visco-elasticity property of asphaltic material is very crucial because it determines how it survives. If the elasticity is low, it can harden and break or wear out easily. The presence of small stone on surfaces is a result of weakening bonding property as the material ages.

After the winter season, the frozen water inside the cracks melts down and leaves empty spaces. Those spaces are filled with material from blacktop, and they form things like potholes. Water should be prevented from seeping down pavements through sealing cracks or applying overlays. Pavements that have multiple small cracks can be repaired through overlay or resurfacing.

When heat from the sun comes into direct contact with the blacktop, it makes it harder. As it becomes brittle and delicate, it unravels and begins to develop cracks. Sealcoats are applied on blacktop to make it more elastic and protect it from ultraviolet rays. Cracks begin as small opening, which may not be initially visible. The tiny hairline cracks are the first to be noticed and they occur as the pavement chances it color from the jet-black to grayish.

Besides water and sunlight, there are other aspects, which will cause your blacktop to degrade, and they include salts, oils, and transmission fluid. Tree roots can also cause damage on blacktop needless to mention the heavy vehicular traffic. If there are defects on driveways or parking lots, you need to consult asphalt paving Phoenix contractors to make the necessary repairs. Any defects on pavements should be dealt with in its early stages to prevent costly repairs in future.
