Driveway Construction With Asphalt Paving Phoenix Contractors

By Essie Osborn


When constructing parking and driveways, you need to choose the right material such as asphalt. The material you use should be able to withstand heavy traffic and the effects of environmental changes. If you settle on asphaltic hot mix, you can consult asphalt paving Phoenix contractors to start designing and laying down the structure.

To get a durable and long lasting asphaltic pavement, you need to ensure the contractor does everything right from the laying of foundation or the base to the application of blacktop. Asphaltic driveways and parking lot are made using crushed stones and aggregate, which form the sub base as well as sand and asphalt cement. With a properly installed asphaltic paving surface, it can last for about 25 years or more.

Cracks are some of the defects you will encounter when you have laid down your asphaltic paving surfaces. However, there are different methods that can be used to repair cracks. Application of crack fillers help in protecting driveways and pavement surfaces from the aging effects caused by repeated heating as well as cooling from weather changes.

A crown to edge sloping grade is essential for your pavements in order to drain away the water collecting on surfaces. At the edges, water should also be directed away from the road and from any building structures. When cracks occur, they have to be repaired as soon as possible. Cracks are not a good sign to the structural integrity of roads.

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.

If cracks have developed extensively, you need to use other methods like crack filling and patching or overlays. Regular inspection of parking lots and driveways is needed in order to identify sessions that are showing cracking and other forms of defects such as upheavals and depression. The presence of cracks may indicate that the base is unstable or the underneath soils are shifting.

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.

When cracks are not filled immediately, they can encourage the growth of small plants and trees seedling. The plants and tree seedlings extend their root systems and exacerbate the cracking. There are different types of crack fillers in the market and the contractor you are dealing with should help identify the right ones. It is important to use the right crack filler and applicator. The width of cracks helps dictate the kind of application you need to use. Whether it is a hot applied sealer or a cold applied asphaltic emulsion, it should be done properly.
