Asphalt driveways are prone to degradation over-time due to several reasons such as weather changes and traffic pressure. Being reliable, durable and low maintenance, asphalt pavement is a substantial investment so choosing the right Edmonton Driveway Paving contractor is essential. The process of driveway paving requires the right materials, heavy equipment as well as experience and skill. The whole process has a series of steps that leads to successful driveway paving. Therefore, you must make sure that these are a vital part of the contract.
Removal of the Current Surface
Paving an asphalt structure on top of the damaged driveway causes the new pavement to crack easily. The contractor will first evaluate the driveway, and then dig out the unusable base. This may involve removing loose gravels, stumps, clay, and other soft material. This is an essential step, because if there is cracking in the asphalt, it will easily move upwards to the new pavement within a short period. To allow correction of sub base, removal of the current surface is vital.
Grade the Subsoil
Grading is necessary to let the water run off your pavement in order to prevent a collapsed driveway. The contractor will grade the subsoil so that water runs down towards the road and also sideways away from your house. The contractor will then compact the base soil by running a drum roller over it. This helps in removing dirt to prevent any damage in future.
The next step is to add crushed rock. The contractor will use coarse and sharp rocks that compact well to allow for proper drainage. The thickness of this layer varies depending on your subsoil. If your underlying soil is clay based, then you will need a huge amount of crushed rocks to get the solid base for a driveway. After this, the contractor compacts the crushed rock layer and usually gives it a week’s time to settle.
Lay the Asphalt
The type, size and thickness of the asphalt needed will be specified, depending on the surface as well as the environment in the area. Usually, the best layer thickness is 2 to 3 inches. The hot mix asphalt is then layered on the driveway.
Compacting and Finishing
After the asphalt is spread, the compacting process begins. It is advisable to do it on a sunny day as it makes the task easier and the asphalt cures better. The edge treatment commences after compacting. The edges should be hand tamped at 45-degree angle. It keeps the edges from eroding and strengthens your driveway. On completion of the whole process, your driveway gives you the rich, black look you want.
There are a number of ways contractors can cheat you with shortcuts on your driveway. It is essential you wisely choose the right service for your driveway paving.
