Parking Lot Resurfacing
Asphalt Resurfacing, or overlay, is a way of repairing existing asphalt by paving overtop of it. There are certain preparations for constructing an overlay, which include milling, or shaving, the original pavement into a more even surface to help match the existing landscaping around it. Areas that are in very poor condition must be removed and patched. The pavement is cleaned, an adhesive is laid down, and then the new asphalt can be applied in layers.
Milling is when part of the surface of a paved area is removed and ground up to be used as the aggregate in the new pavement. Just enough of the surface is removed to correct the uneven road surface caused by bumps, loose aggregate, rutting, and depressions. This process is responsible for recycling about 95% of asphalt pavement needing to be repaired.
Shaving a process that uses a series of diamond tipped saw blades mounted on a rolling shaft that shave the upper surface of a asphalt pavement to remove bumps, restore pavement drivability , and improve surface friction.
Overlaying is less expensive than fully reconstructing a paved surface, and typically takes less time, making it a great option when considering major asphalt repairs. This is more appealing for a large parking lot as it is less costly to resurface a large area then to replace it. However, the areas that now puddle will again puddle since in most cases, the grade cannot be alter by just paving an overlay. Also, any problems with the sub base will still be there so any cracking in the existing asphalt will come back up through the overlay- this is called “reflective cracking”.
Life expectancy for an overlay or resurfaced parking lot is 8-10 years if properly maintained.
