Construct Quality Pavements Through Asphalt Paving Phoenix Contractors

By Essie Osborn


Although there are different materials that can be used to install pavements, asphaltic hot mix proves to be durable, strong, and beautiful. Insured and bonded asphalt paving Phoenix contractor will help you design your pavements using the best construction practices and quality materials. This will ensure that you get a structure, which can support the intended traffic while also lasting for long.

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.

But there are cracks that cannot be sealed with overlays. The purpose of applying an overlay is to restore the elasticity of pavements and improve its traction effects. Cracks that are more pronounced like fatigued cracks need to be patched. Patching entails excavating the ground and removing the lose material, and then applying the pavements a fresh.

Frozen water enlarges and widens those cracks and when warmer months arrive, the frozen water melts down leaving voids. The empty spaces are filled with materials from above forming potholes. Repairing cracks in time ensures that your pavements do not suffer from water damage. Properly maintained driveways and parking lots will cost you less in repairs and maintenance in the long term.
