7 Steps For Getting Your Asphalt Job Done Just Right
When an asphalt pavement is properly prepared, the results are likely to last for a very long time. For you, this will mean lower maintenance requirements. This is cheaper and more convenient. It will also take longer before you have to replace the pavement. To ensure an asphalt job is properly done, there are seven key steps that must be followed.
Demolition and Removal
Whichever surface was there before the asphalt will have to be removed. Whether it is previously laid asphalt, concrete, or something else, it should be properly demolished and removed using heavy machinery. Some of the old asphalt and concrete can be recycled. This is a good way of making paving an environmentally friendly project.
Grading and Sloping
The area where the pavement will be laid needs to be properly graded and sloped to ensure water will be able to run off with ease. One of the biggest factors contributing to the damage of asphalt is poor drainage. This starts by not doing proper grading and sloping of the pavement.
Preparation of the Sub Base
The sub-base is probably the most important part of an asphalt pavement. If the sub-base is properly prepared, a pavement can serve you reliable for years to come, only requiring maintenance at the surface level. The sub-base is what supports the pavement and also reduce winter damage.
Proof Rolling
You shouldn't wait until the asphalt is laid to find out if there is a problem with your subgrade. This is why proof rolling is necessary. This is done after the compaction of the sub-base. If the proof roll reveals any problems with the sub base, these can be fixed before the next step.
Adding the Binder
The binder is what will hold the asphalt surface. It consists of large aggregate that is mixed with oil. If the binder is strong, the asphalt surface will be, too.
Adding the New Surface
Finally, the asphalt surface is added on top of the binder and it should provide a smooth surface for traffic on top.
Transitioning
The pavement will have to connect to existing road surfaces such as parking lots or roadways. Ensure that your asphalt contractor puts in place proper butt joints to ensure a smooth transition. Once this is done, the final roll can follow to ensure no bumps of stone or aggregate are still poking through the surface of your new asphalt pavement.
