Asphalt Patching
Patching is a common asphalt repair in areas where the asphalt has cracked, but the base is still stable, or in areas where potholes have occurred. This process begins by cleaning the repair area and applying a tack coat to help the new asphalt adhere to the existing surface. A layer of asphalt is then installed upon the existing surface; the depth will vary from 1”-2.5” depending on the severity of the existing damage. Patching is a cheap solution to asphalt defects; however it will not last as long as removal and replacement. Eventually cracking will reflect through the new patch, or spread beyond the patch.
Asphalt Removal & Replacement
Asphalt removal and replacement or as we call it “peel & pave” is another common repair. The repair is often prescribed for areas with cracking and or base/failure. This process begins by saw cutting the perimeter of the repair area in order to achieve a clean edge. After the edges are saw cut, the existing asphalt is removed to the depth specified. Typically the new asphalt is installed in 2 lifts; a binder course usually at 3” is followed by a 1” top course. The depth of repair will vary dependent upon the extent of existing damage, and/or the load requirements needed to be met. By adding up to 10 times more life span than patch work, asphalt removal & replacement is often a very cost effective fix for your surface’s distressed areas.
Mill & Pave
Milling, or grinding, takes a much different approach than either patching or peel & pave in that it removes built-up layers of deteriorated asphalt down to a specific depth, making room for a new surface, by actually grinding up the existing asphalt into a tiny like gravel. The millings, as they are often referred to are then hauled off site and can easily be recycled. The newly grinded surfaced is then layered with tack and set to receive a fresh smooth coat of asphalt. In many cases this type of fix is done on much larger areas where a peel and pave or patch is just not sufficient.
