Build Strong Pavements With Asphalt Paving Phoenix Contractors

By Minnie Whitley


For you to have durable and long lasting pavements, you need to use quality materials, the best construction practices, and maintain the structures in good form. By consulting asphalt paving Phoenix contractors, you ensure that you get driveways designs that can resist the environmental and manmade effects. Different factors will damage driveways and parking lots designed of asphaltic materials.

At this point, you will discover that fine hairline cracks are forming. These cracks are undetectable at first, but as they enlarge, they become detectable. When you see these types of cracks, it means that your asphaltic material is not imperious to water. Soon you will have water seeping down pavements and settling on sub base.

Sealcoating helps prevent the formation of cracks by making the blacktop more elastic. Moreover, water is another element, which causes damages on pavements. Water collecting on top of blacktop can seep down and settle in sub grade layer. The same water causes the sub base material to loosen up thus weakening the strength of the base. A weak base cannot sufficiently support the vehicles weight. Also, weakened base is not able to support the blacktop.

When you lay down your pavements, you also need to inspect them regularly to ensure that are functioning properly. Asphaltic materials are an ideal choice for installing pavements but they also come with their own set of challenges. Asphalt is a material that suffers from effects of natural elements like sunshine, snow, and water.

When that water unthaws, it leaves empty spaces. The spaces are filled with blacktop material, something that leads to formation of potholes. Different methods are applied when repairing damages on roads. If you have small crack such as the fine hairline fissures, they may not be a threat to the quality of your pavements. However, if you do not restore them in advance, they can grow to be big cracks.

If you have large cracks, you can use methods such as patching. With patching, it is ideal for large cracks that only cover a small area. For example, you can patch areas that have developed alligator cracks. Patching may also be used to repair potholes. However, when you have extensively damaged road sections, you may need to remove and replace asphaltic material.

If you have small cracks that cannot be restored with use of sealcoats, it means the other option you have is to apply an overlay. Overlays are cheap options for repairing large sections of driveways or parking lots that have developed small cracks. However, this process has some limitations. While you may restore cracks using overlay technique, the procedure cannot be used many times.

When you have tree extending their root networks underneath the pavement structure, they can put upward pressure, which causes the road to tear apart or form bulging surfaces. Potholes form when cracks have been allowed to continue forming thus leading to the asphaltic material breaking apart. On the other hand, sink holes are formed when there is insufficient sub base to sustain the load demands of pavements. While a good asphaltic pavement will not last forever, it needs to be properly maintenance in order to extend its life expectancy.
