Driveway Construction With Asphalt Paving Phoenix Contractors

By Essie Osborn


Hot mix asphalt is a less expensive method of installing pavements in new and old homes as well as business properties. If you are planning to pave your surfaces, you may consider this material as your choice. With asphalt paving Phoenix contractors, they can design and pave surfaces using the best practices and state-of-the-art equipments.

You need to seek the helping hand of an experienced and qualified contractor. If pavements are not designed using the best practices, they can fail prematurely. The contractor should use the right depth of aggregate and sufficient thickness for blacktop. The compacting process for aggregate material should also be done properly.

However, it requires proper maintenance to prolong the life expectancy of the surface. Once you have installed the blacktop, you will find that it is more flexible when new. This is because it retains most of the light hydrocarbon oils. However, as it starts to age, the oils dry up and the surface becomes brittle.

The fillers also minimize water damage. Any cracks regardless of their nature should be addressed immediately they are seen. Different repair methods are used to restore cracks depending on the type of cracking, the causing factor, and extend of the cracks. Cracks in driveways may occur due to insufficiently compacted sub base layer.

If the aggregate materials is not applied and compacted using rollers, it may weaken and cause cracks. When the ground freezes as may happen during the cold weather, it leads to formation of bulges. After the winter, the frozen water underneath driveways unthaws and the ground levels out. The up and down movements caused by bulging and leveling of driveways lead to cracks in the long run.

Many cracks are noticed in spring season and you need to ensure they are repairs. Overlays or resurfacing is done if your pavements have developed depression and cracks. If large sections of driveways have small cracks that are visible, crack filling may not be appropriate because filling each individual crack is a big task. However, by using a resurfacing procedure, the cracks are sealed at once. This is a cost effective way of repairing small cracks.

The movement of soils may cause the sub base to be unstable. If cracks have developed, crack filling can be applied to restore the damaged sections of your driveways or parking lots. Crack fillers prevent further damage to the road structures. Presence of cracks allows water to start seeping underneath your driveway. Water results to serious damages when it finds its way into the sub grade layer. The increasing moisture weakens the soils and makes the sub base unstable. In addition, the water settling down in cracks expands during the cold months of winter.

If you are designing a new driveways or parking lot, you should have a sketch of the home and the footprint of the desired pavement surface. This is critical in obtaining accurate quotes from a contractor. You can walk the site with the expert pavement contractor and have him stake or paint lines where the driveways will lay. The subject of installing a sloping grade or crown to edge slope has to be discussed in order to take care of drainage issues. A crown to edge design or grading allows water to flow to edges where it is drained in the right drainage channels.
