You may have admired the beauty of a newly installed asphalt parking lot, enjoyed the smooth ride you experienced on an asphalt highway, or heard that asphalt is much more economical than concrete to install, repair and maintain. There are many reasons to make asphalt your choice of paving material. However, you may be wondering how a paving company builds a new asphalt pavement.
What Are the Steps for Asphalt Paving Installation?
What Do Asphalt Contractors Do First?
The first step will depend on whether the job is for an overlay, a reconstruction, or an entirely new pavement. For a parking lot overlay or an asphalt driveway resurfacing project, the first step will be to clear the work area so that the contractor can make any necessary repairs. For a reconstruction, the contractor will need to remove the existing pavement and haul it away. If the contractor needs to build a pavement on undeveloped land, he will need to remove the vegetation and any structures before performing a rough grade of the terrain.
Why Is Parking Lot Repair Needed for an Asphalt Overlay?
When installing an overlay, the contractor can use a milling machine to remove the exact depth of the pavement required for the overlay. If the damages do not extend far into the pavement, milling may address some of the issues. However, if the damage goes deeper, it should be repaired. If not, the damage pattern can be transferred to the overlay.
What Happens During an Asphalt Pavement Installation After the Site Is Cleared?
For a reconstruction or new construction, the next step will be to grade the site. The proper grade is necessary to ensure proper drainage. The preparation of the subbase follows the grading process. The subbase provides support for the pavement, and it also serves as a frost barrier to help minimize damage to the pavement when the ground freezes and thaws. To ensure the stability of the pavement, the subbase must be properly compacted. Your contractor may perform a proof roll to check for any soft spots so that they can be repaired before installing the binder layer.
What Are the Final Steps When Installing an Asphalt Pavement?
When installing an overlay, the final steps begin after the pavement has been milled and repaired; your paving company may choose to apply a tack coat before proceeding. For other types of installations, the final steps begin after the binder layer is in place. One layer at a time, the contractor’s crew will introduce hot asphalt, spread it, and compact it. The number of layers will depend on the design specifications for the pavement’s intended use. For example, residential paving that is designed to only support two typical vehicles does not need to be as thick as a pavement that will support numerous heavy trucks as well as a high volume of passenger vehicles. Whether building a new pavement or installing a parking lot overlay, the final layer of asphalt will be the surface course. Next, the contractor will make sure that transitional areas between the new pavement and adjoining pavements are smooth and easy. The last step will be the final roll to provide additional smoothness and compaction.
