Asphalt Patch Repair

Asphalt patch repair is the commonest procedure for asphalt maintenance. It replaces specific areas of an asphalt pavement, usually those with potholes.

The asphalt around the pothole must be removed, including a foot of undamaged asphalt radiating around the perimeter of the pothole.Accurate Road Construction team members prep the work area by delineating a rectangle or square around the pothole that includes this surrounding foot of good asphalt; this area is the piece of asphalt that will be removed. The asphalt is removed, and the hole is cleared of debris and cleaned.

Next, tack is applied to the bottom and sides of the hole to help the new asphalt adhere. The hole is then filled with hot or cold asphalt (determined by the season,) and the new asphalt is compressed using a multi-ton vibratory plate or roller.

Finally, the edges of the filled hole, or patch, are sealed using hot or cold asphalt and aggregate chips or sand. In some cases, the base rock underneath the asphalt pavement may also need to be replaced.

Asphalt Replacement

Asphalt removal and replacement may become necessary if an asphalt pavement has not had regular maintenance. Small cracks that inevitably form on the asphalt surface deepen over time, allowing water infiltration into the lower levels of asphalt. When water gets into these deep cracks, it can create holes in the substrate, structurally weakening the asphalt. These small surface cracks will also spread across the asphalt, then run deeper below those areas of the surface, so that large parts of the asphalt surface and their lower levels become affected. When this happens, superficial repairs are not sufficient to fix the structural damage. The asphalt must be removed and replaced.

Accurate Road Construction will evaluate the structural damage to your asphalt pavement and determine whether the entire pavement must be removed, or whether parts of the pavement are strong enough to remain in place so that only partial removal and replacement is necessary.

The process of asphalt removal will begin with breaking up of the perimeter around the damaged area or areas using a saw cutter or jackhammer. The damaged asphalt will then be removed and hauled away.

At this point, we will examine the sub-base for any problems there. These can include shallow utilities, excessive moisture, general structural deficiencies, or a sub-base that was improperly prepared in the first place.

These problems must be corrected before the asphalt pavement can be replaced, and they often are not apparent until the damaged asphalt has been removed.

Once any problems with the substrate have been corrected, it will be re-graded and compacted. Then replacement can begin. The edges of the replacement area will be cleaned, and a sticky, adhesive tack coat will be applied in order to help the new asphalt that will be poured in bond to the stone base and to the adjacent asphalt.

Resurfacing or Overlay

If your asphalt surface is in an extreme state of disrepair, the good news is that you can resurface it at relatively low cost with results that will last a long time. Asphalt resurfacing or overlay is the process of paving a new layer of asphalt on top of an existing, damaged one. The damaged areas of the old asphalt can be removed and patched, and the new layer of asphalt paved over them.

Signs that it is time to resurface your asphalt include: depressions in the pavement, such as ruts or wheel depressions, often noticeable by puddles of water that sit in them after a rain; surface erosion, noticeable by pitting or pock marks on the surface of the asphalt and a generally rough and uneven appearance; significant areas of alligator cracking or fatigue cracking, which looks like the skin on an alligator’s back because the intersecting cracks form a series of little blocks in the asphalt; patch repairs in various areas, marking previous sites of isolated structural failure.

Resurfacing is a multi-step process that involves cleaning the asphalt area to be resurfaced, leveling out irregular rises or dips in the asphalt surface, modifying all drainage structures within the area, and much more, most of which is specific to the site. There are different techniques used during resurfacing, including geotextile reinforced resurfacing or Petromat, butt joint or grinding, and leveling binder.

Petromat is a nonwoven, geotextile fabric that increases the life span of asphalt overlays. The fabric is laid over the old layer of asphalt before pouring on the new one, and serves as a waterproof seal between the two layers and structural support for both. Before it is laid, the Petromat is coated with asphalt cement tack in order to waterproof it and help it bond the old and new layers of asphalt. In addition to forming a waterproof barrier, the Petromat will also absorb stress on the surface layer, prevent cracks in the old asphalt from spreading to the new asphalt (otherwise known as reflective cracking,) and protect the old layer of asphalt from the external destructive elements that affect the new asphalt, which could otherwise damage the old asphalt and necessitate removal of both layers.

Butt joint or grinding is necessary to join the new overlay surface with an adjacent existing surface, such as a concrete pavement. The old asphalt must be removed from the border area along the other surface and then replaced in order to ensure that the asphalt repaving is level with the edge of the other surface. The overlay itself should never be tapered or ground down to meet adjacent surfaces because this severely impairs the strength of the overlay. Instead, adjacent surfaces themselves should be ground down to meet the overlay.

Leveling binder is used in resurfacing to enhance grades and improve the strength of the asphalt. Hot asphalt is poured into dips in the existing asphalt, filling them to varying depths. This adjusts the degree or angle of the asphalt surface to restore the original, appropriate gradient or slope.
